TESS-validated Gaia DR3 Pulsating Variables of δ Scuti and γ Doradus: II. 360+ Eclipsing Binaries with δ Scuti and γ Doradus Components
<div> <div> <div> <p>I present serendipitous discoveries of 380 eclipsing binaries with δ Scuti and γ Doradus pulsators, 46 eclipsing binaries exhibiting rotational variability, and 8 new RR Lyrae stars, identified for the first time during a validation project of pulsating variables from Gaia Data Release 3. Gaia DR3 Part 4 Variability released 12.4 million variables, including 748,058 pulsating variable stars of `DSCT|GDOR|SXPHE' types among the variability classification results of all classifiers -- 9,976,881 objects (in the file vclassre.dat, https://cdsarc.cds.unistra.fr/viz-bin/cat/I/358}). Among 75,369 analyzed stars, I confirmed 12,145 δ Scuti stars (including 8,710 new) and 8,192 γ Doradus stars (including 7,531 new). This work has significantly expanded the bona fide DSCT and GDOR catalogs to include 98,968 and 19,466 stars, respectively, providing a valuable resource for future studies. The discovery of the remarkable number of pulsating binaries underscores the significance of this project in validating Gaia’s variable star catalog. </p> </div> </div> </div> <p>The attached CSV files report the current validation results.

Variability Census of Legacy Catalogs: New Pulsating Variables and Eclipsing Binaries
<div> <p>I present the preliminary results of a comprehensive variability census of the four legacy catalogs: BD (+CD+SD), HD, SAO, and PPM. This dedicated survey project aims to identify bright A-F type variable stars using high-precision space photometry from the Transiting Exoplanet Survey Satellite (TESS ) and Gaia. Phases I through V of this survey, encompassing analyses of 193,940 A-F stars selected from the aforementioned catalogs, have been completed. To date, the project has yielded a substantial number of new variable star discoveries, including: over 14,510 new δ Scuti stars, more than 18,382 new γ Doradus stars, and over 2,354 new eclipsing binary systems, with approximately 360 binaries exhibiting pulsations in the primary components. Furthermore, thousands of rotational variables and dozens of Heartbeat stars and RR Lyrae stars have been identified, demonstrating the power of this systematic approach in revealing the rich diversity of stellar variability. Due to potential blending and contamination in TESS photometry, the binarity of a few pulsating stars or those eclipsing binaries exhibiting superimposed intrinsic pulsations of <em>δ</em> Scuti and <em>γ</em> Doradus types should be rechecked. Follow-up studies of individual systems are necessary to resolve contamination issues and accurately identify the true source of variability.</p> <p> </p> </div> <div> <p>The full list of newly identified variable stars is presented in machine-readable format in the attached file `PPM_AFstars_NewVar_R5.csv', and an atlas of selected representative light curves is provided as a separate PDF.</p> </div> <p> </p> <p><strong>Citation:</strong> Zhou, Ai-Ying: 2023, <em>Res.

W0TBR April 2024 Eclipse WWV Doppler Shift
<h2><strong>April 2024 Solar Eclipse Data via W0TBR</strong></h2> <p>W0TBR recorded Doppler drift of 15MHz WWV/WWVH carrier signals prior to and subsequent to the April 8 2024 solar eclipse.</p> <p>Although the W0TBR station was not in the direct path of the solar eclipse - with about only 33% occlusion at maximum shadow - the Doppler shift was recorded to determine any effect as compared to other shifts to be recorded within the direct eclipse path or within the midpoint of the signal path between WWV/WWVH and the recording station.</p> <p>W0TBR is located in Grid CN85qn - Lat. 45.555N & Lon. 122.623W at an elevation of 68.5m ASL.</p> <p>Antenna used is dual band inverted V fan dipole resonant on 20 and 17 meters with an apex at 10 meters above average terrain and tuned for max signal at 15MHz.</p> <p>Antenna feed is terminated at each end with 1:1 balun to minimize noise and non-resonant effects.</p> <p>Radio used is a Flex 1500 SDR stabilized with a 10MHz OCXO. Radio was tuned to 14.999MHz USB with AGC deactivated and RF gain fixed at value of 45/100.</p> <p>Received +/- 1kHz signal was directly fed through Conexant audio chip of HP 600G3 computer into Spectrum Lab (SpecLab) software.</p> <p>SpecLab (V 2.99 b15) was configured similar to that used by WA9VNJ for the 2017 solar eclipse recordings: 512K FFTs with 75% overlap resulting in readings every 12 seconds.</p> <p>SpecLab time, peak frequency and amplitude data were recorded from 0143 UTC to 2359 UTC on April 08 2024 and saved to a text file.</p> <p>Screen shots of the frequency shifts (+/- 3Hz) were taken each two hours for a total of six hours around the local maximum solar shadow which began about 1733 UTC, peaked at about 1825 UTC and ended about 1919 UTC. Note that the original SpecLab screenshots are in vertical time orientation; in order to provide a comparable view where time is on the horizontal axis the views are inverted and ‘stitched’ together for the final view’s full six hour period.</p>

Catalogs of Eclipsing Binaries with Pulsating Components, δ Scuti stars and γ Doradus stars
<p>I present a comprehensive, up-to-date catalog of <strong>3324</strong> <strong>eclipsing binary star systems containing pulsating components </strong>(not updated in this version). The initial compilation builds upon existing lists of `oscillating Algol-type eclipsing binaries' (oEA) harboring δ Scuti stars. However, the catalog expands upon this foundation to encompass a broader range of pulsating binary systems identified in recent years. This new catalog is valuable for researchers studying binary stars' evolution and pulsating stars. It incorporates various pulsating variable types across the Hertzsprung-Russell diagram, including δ Scuti stars, γ Doradus stars, β Cephei stars, Cepheids, and red giants exhibiting solar-like oscillations. However, this catalog is NOT an exhaustive list of eclipsing binaries with pulsating components of the above types and it is subject to updates. </p> <p>Many stars in this catalog are potentially interesting for further studies. Due to potential blending and contamination in TESS photometry, the binarity of a few pulsating stars could be attributed to neighboring eclipsing binaries. Follow-up studies of individual systems are necessary to resolve contamination issues and accurately identify the true source of variability. If you use part of the catalog in your research, please cite: Zhou, A.-Y., 2010, arXiv e-prints (DOI: 10.48550/arXiv.1002.2729) (ADS: https://ui.adsabs.harvard.edu/abs/2010arXiv1002.2729Z/abstract)</p> <p>In addition, I have also included the up-to-date catalogs of <strong>118,410 δ Scuti stars</strong> and <strong>41,622 γ Doradus stars</strong>, featuring thousands of unpublished discoveries.

Accessible Oceans: Auditory Display. Zooplankton Daily Vertical Migration Gets Eclipsed!
<p>The nine tracks make up an auditory display of the daily vertical migration of zooplankton off the coast of Oregon. The tracks in the auditory display are comprised of data sonifications and contextual audio supports (dialogue, auditory icons, and music). You may <a href="https://samply.app/p/92HixRBFY6YEyUgjzO1Y">listen online here</a>.</p> <p>The ocean data comes from the National Science Foundation (NSF) Ocean Observatories Initiative (OOI) and the display is based on the <a href="https://datalab.marine.rutgers.edu/ooi-nuggets/zooplankton-eclipse/">OOI Nugget</a> developed by Dr. Leslie Smith and Dr. Lori Garzio. Please note that there is no track 1B in this version. We removed track 1B in order to reduce redundancy in the display. </p> <p>The “Accessible Oceans” AISL Pilots and Feasibility study aims to inclusively design auditory displays that support the perception and understanding of ocean data in informal learning environments (ILEs).

December 2021 Eclipse Monitoring of WWV at 5 MHz and 10 MHz by K1FR Using FlexRadio 6700/GPSDO and fldigi
<p>This dataset contains observations of WWV at 5 and 10 MHz gathered from December 1 through 10, 2021 as part of the study of the effects of solar eclipses on the ionosphere. The data was collected by amateur radio station K1FR located at 38.828, -77.104 using a FlexRadio 6700 with GPSDO connected to a long wire antenna. The fldigi application was used to analyze and record the received frequency of the WWV station at one second intervals. The dataset includes .CSV files of these measurements.</p> <p>Three independent receivers were created within the 6700 - one for 5 MHz and two for 10 MHz. The first two receivers' data are included in this dataset. Files named analysis_xxxxx-K1FR-1 are for 10 MHz, and those named analysis_xxxxx-K1FR-2 are for 5 MHz. The third independent receiver was used to capture realtime audio from WWV at 10MHz which will be included in a separate dataset.</p>
December 2021 Eclipse Monitoring of WWV at 10 MHz by K1FR Using FlexRadio 6700/GPSDO and Audacity
<p>This dataset contains observations of WWV 10 MHz gathered from December 1 through 10, 2021 as part of the study of the effects of solar eclipses on the ionosphere. The data was collected by amateur radio station K1FR located at 38.828, -77.104 using a FlexRadio 6700 with GPSDO connected to a long wire antenna. The Audacity application was used to record the realtime audio of the receiver which was in the USB mode and tuned to 9999.000 kHz thus producing a 1000 hz tone at the carrier frequency of WWV. The AGC on the receiver was set to “ON-medium.” <strong>PLEASE NOTE:</strong> due to operator error, the metadata in the Audacity generated .WAV files show that the AGC was “OFF”.</p> <p>See DOI 10.5281/zenodo.5775043 for data taken via the fldigi application on the same audio stream simultaneously. That dataset has .CSV files of the apparent doppler of WWV 10 MHz, and these files are named “analysis_xxxxx_K1FR-1.CSV.</p>
