The excess of cool supergiants from contemporary stellar evolution models defies the metallicity-independent Humphreys-Davidson limit
<p>Input files and simulation results for stellar evolution tracks computed for the paper "The excess of cool supergiants from contemporary stellar evolution models defies the metallicity-independent Humphreys-Davidson limit", as well as synthetic populations generated and catalogues of observed cool supergiants in the Magellanic Clouds used in the analysis. Version 10398 of MESA was used for the simulations. More details in the README.txt file and in the paper.</p>

Type IIP Supernova Progenitors. III. Blue to Red Supergiant Ratio in Low-metallicity Models with Convective Overshoot (Dataset)
<p>MESA input and output files associated with the published journal article Wagle et al. (2020; doi:10.3847/1538-4357/ab8bd5). We used MESA version r-10398 and MESA SDK version 20180822 to run these models.</p> <p>The "MESA_inputs.tar.gz" file contains work directories for initial mass of 13 solar mass and several overshoot parameter (f) values as listed in Table 2 of the published article. The models can be run directly from each working directory ("f_*") by making (./mk) and then running MESA (./rn), after instantiating MESA SDK. The run-script ("rn") is modified to start a MESA run from the pre-main-sequence (preMS) stage through core-collapse (CC) stage, if the LOGS and photos directories are absent. Otherwise, it restarts MESA from the latest "photo" binary file saved in the photos directory (that is, it assumes that the previous run was interrupted and restarts the run. So, to start a fresh run delete the "LOGS" and "photos" directories.) Each working directory has "run_star_extras.f" file which is modified to save the compactness parameters, mu_4, M_4 as extra history columns, as well as, to implement additional temporal resolution constraints as explained in section 2.2 of the article. Any other combination of mass and f-value from Table 2 of the article can be run by changing initial_mass in "inlist_control" file, and overshoot values in "inlist_f*" file.</p> <p>Each "*M_z0.006_f_*.tar.xz" file has a "LOGS" directory that contains corresponding "history.data", "profile.data" at core-collapse (CC) stage and saved model ("*.mod") at CC stage for each mass and f-value combination from Table 2 of the paper. (Note: Please copy the tar.xz files for each mass in a separate folder before decompressing them, in order to avoid overwriting the folders with the same f-values.) The LOGS directory also contains a folder "png_plots" that has saved ".png" files generated by "inlist_pgstar". These files can be used to generate stellar evolution movies using the "images_to_movie.sh" script available in the MESA SDK.</p> <p> </p>

New results of the LIFE project: characterization of the A5Ib-II supergiant 19 Aur and the newest sample of magnetic stars
<p>The Large Impact of magnetic Fields on the Evolution of hot stars (LIFE) project is focused on detecting magnetic fields in bright evolved OBA giants and supergiants to investigate the evolution of these stars from their main sequence (MS) forms into their late post-MS stages. We have previously reported that the longitudinal surface magnetic field of these objects may be very weak, but the field configuration resembles those of main sequence hot stars. Here we present the newest results of the survey from spectropolarimetric observations using the ESPaDOnS instrument of the Canada–France–Hawaii Telescope. These results include the first characterization of a truly evolved OBA supergiant, the A5Ib-II supergiant 19 Aur, updates to the project’s detection rates, and newly discovered magnetic stars.</p>
