MOBSTER - At the crossroads of stellar astrophysics in the upper HR Diagram
<p>Contrarily to low-mass stars, in which dynamo-generated surface magnetism is essentially ubiquitous, only about 10% of stars with radiative envelopes (O, B and A) exhibit detectable magnetic fields at their surfaces. Yet, this small magnetic subpopulation includes potential progenitors of exotic astronomical objects, such as high-mass stellar black holes (even at solar metallicity) and magnetars. Therefore, there is a strong motivation to learn more about the as-yet misunderstood formation of these stars, and what is currently lacking is a robust statistical basis to interpret their properties. In this talk, I will briefly review massive star magnetism and some of the critical gaps in knowledge that currently plague their study. I will then discuss the observational limitations that prevent us from learning more, and argue that all-sky broadband photometric missions such as the Transiting Exoplanet Survey Satellite (TESS) offer a valuable indirect method of addressing these limitations. Finally, I will present the MOBSTER (Magnetic OB[A] Stars with TESS: probing their Evolutionary and Rotational properties) collaboration, and highlight some of its early results, as well as offer a glimpse of the road that lies ahead.</p>
Modules for Experiments in Stellar Astrophysics (MESA): Time-Dependent Convection, Energy Conservation, Automatic Differentiation, and Infrastructure
<p>We update the capabilities of the open-knowledge software instrument Modules for Experiments in Stellar Astrophysics (MESA). The new auto_diff module implements automatic differentiation in MESA, an enabling capability that alleviates the need for hard-coded analytic expressions or finite difference approximations. We significantly enhance the treatment of the growth and decay of convection in MESA with a new model for time-dependent convection, which is particularly important during late-stage nuclear burning in massive stars and electron degenerate ignition events. We strengthen MESA's implementation of the equation of state, and we quantify continued improvements to energy accounting and solver accuracy through a discussion of different energy equation features and enhancements. To improve the modeling of stars in MESA we describe key updates to the treatment of stellar atmospheres, molecular opacities, Compton opacities, conductive opacities, element diffusion coefficients, and nuclear reaction rates. We introduce treatments of starspots, an important consideration for low-mass stars, and modifications for superadiabatic convection in radiation-dominated regions. We describe new approaches for increasing the efficiency of calculating monochromatic opacities and radiative levitation, and for increasing the efficiency of evolving the late stages of massive stars with a new operator split nuclear burning mode. We close by discussing major updates to MESA's software infrastructure that enhance source code development and community engagement.</p>
