Dipole low-order g mode instability of metal-poor low-mass main-sequence stars due to the -mechanism
Takafumi Sonoi, Hiromoto Shibahashi
We analyzed vibrational stability of metal-poor low-mass main-sequence stars due to the -mechanism. Since outer convection zones of the metal-poor stars is limited onl…
Vibrational Instability of Metal-Poor Low-Mass Main-Sequence Stars
Takafumi Sonoi, Hiromoto Shibahashi
We find that low-degree low-order g-modes become unstable in metal-poor low-mass stars due to the -mechanism of the pp-chain. Since the outer convection zone of these…
Fully Nonadiabatic Analysis of Vibrational Instability of Population III Stars due to the -Mechanism
Takafumi Sonoi, Hiromoto Shibahashi
A linear nonadiabatic analysis of the vibrational stability of population III main-sequence stars was carried out. It was demonstrated that, in the case of massive stars with $M \g…
Vibrational instability of Population III very massive main-sequence stars due to the -mechanism
Takafumi Sonoi, Hideyuki Umeda
Very massive stars are thought to be formed in the early Universe because of a lack of cooling process by heavy elements, and might have been responsible for the later evolution of…
