À Propos Strange Pulsations of Blue Massive Stars
Alfred Gautschy
The properties of radial nonlinear pulsations of massive blue stars are computed with the MESA software instrument in its dynamical mode. Pulsational instabilities could be computa…
À Propos Nonlinear Pulsations of R CrB Variables
Alfred Gautschy
Helium-star models were dynamically evolved into the region of the HR Diagram where R CrB variables are found. The MESA stellar evolution code was able to pick up pulsational insta…
On an Early - Post-AGB Instability
Alfred Gautschy
Dynamical stellar-evolution modeling through the AGB phase reveals that radial pulsations with very fast-growing amplitudes develop if the luminosity to mass ratio of stars with te…
A Propos Crossing the Hertzsprung Gap
Alfred Gautschy
The evolution of intermediate-mass and massive stars speeds up considerably after they finish their hydrogen core-burning. Due to this accelerated evolution, the probability to obs…
Overtone Pulsations Revisited
Alfred Gautschy
The shape of light cures of fundamental-mode and of first-overtone pulsators, as observed in RR~Lyrae variables and Cepheids, differ characteristically. The stellar physical origin…
Modules for Experiments in Stellar Astrophysics (MESA): Pulsating Variable Stars, Rotation, Convective Boundaries, and Energy Conservation
Bill Paxton, R. Smolec, Josiah Schwab +14
We update the capabilities of the open-knowledge software instrument Modules for Experiments in Stellar Astrophysics (MESA). RSP is a new functionality in MESAstar that models the…
