Simulating the outer layers of rapidly rotating stars
Frank Robinson, Joel Tanner, Sarbani Basu
This paper presents the results of a set of radiative hydrodynamic (RHD) simulations of convection in the near-surface regions of a rapidly rotating star. The simulations use micro…
Improved calibration of the radii of cool stars based on 3D simulations of convection: implications for the solar model
F. Spada, P. Demarque, S. Basu +1
Main sequence, solar-like stars (M < 1.5 Msun) have outer convective envelopes that are sufficiently thick to affect significantly their overall structure. The radii of these stars…
Entropy in adiabatic regions of convection simulations
Joel D. Tanner, Sarbani Basu, Pierre Demarque
One of the largest sources of uncertainty in stellar models is caused by the treatment of convection in stellar envelopes. One dimensional stellar models often make use of the mixi…
The Effect of Metallicity-Dependent T-tau Relations on Calibrated Stellar Models
Joel D. Tanner, Sarbani Basu, Pierre Demarque
Mixing length theory is the predominant treatment of convection in stellar models today. Usually described by a single free parameter, alpha, the common practice is to calibrate it…
Helium-Abundance and Other Composition Effects on the Properties of Stellar Surface Convection in Solar-like Main-sequence Stars
Joel D. Tanner, Sarbani Basu, Pierre Demarque
We investigate the effect of helium abundance and -element enhancement on the properties of convection in envelopes of solar-like main-sequence stars stars using a grid of 3D ra…
Variation of Stellar Envelope Convection and Overshoot with Metallicity
Joel D. Tanner, Sarbani Basu, Pierre Demarque
We examine how metallicity affects convection and overshoot in the superadiabatic layer of main sequence stars. We present results from a grid of 3D radiation hydrodynamic simulati…
