Calibration of the mixing-length parameter for the MLT and FST models by matching with COBOLD models
T. Sonoi, H. -G. Ludwig, M. -A. Dupret +5
The CoRoT and Kepler missions provided a wealth of high-quality data for solar-like oscillations. To make the best of such data for seismic inferences, we need theoretical models w…
Influence of metallicity on the near-surface effect on oscillation frequencies
L. Manchon, K. Belkacem, R. Samadi +4
The CoRoT and Kepler missions have provided high-quality measurements of the frequency spectra of solar-like pulsators, enabling us to probe stellar interiors with a very high degr…
On the computation of eigenfrequencies for equilibrium models including turbulent pressure
T. Sonoi, K. Belkacem, M. -A. Dupret +4
The space-borne missions have provided a wealth of highly accurate data. However, our inability to properly model the upper-most region of solar-like stars prevents us from making…
Stellar oscillations. II The non-adiabatic case
R. Samadi, K. Belkacem, T. Sonoi
A leap forward has been performed due to the space-borne missions, MOST, CoRoT and Kepler. They provided a wealth of observational data, and more precisely oscillation spectra, whi…
Surface-effect corrections for solar-like oscillations using 3D hydrodynamical simulations
T. Sonoi, R. Samadi, K. Belkacem +3
The space-borne missions have provided us with a wealth of high-quality observational data that allows for seismic inferences of stellar interiors. This requires the computation of…
Angular momentum redistribution by mixed modes in evolved low-mass stars. II. Spin-down of the core of red giants induced by mixed modes
K. Belkacem, J. P. Marques, M. J. Goupil +6
The detection of mixed modes in subgiants and red giants by the CoRoT and \emph{Kepler} space-borne missions allows us to investigate the internal structure of evolved low-mass sta…
Angular momentum redistribution by mixed modes in evolved low-mass stars. I. Theoretical formalism
K. Belkacem, J. P. Marques, M. J. Goupil +6
Seismic observations by the space-borne mission \emph{Kepler} have shown that the core of red giant stars slows down while evolving, requiring an efficient physical mechanism to ex…
Stability Analysis of Strange-Modes in Hot Massive Stars with Time-Dependent Convection
Takafumi Sonoi, Hiromoto Shibahashi
We carry out a nonadiabatic analysis of strange-modes in hot massive stars with time-dependent convection (TDC). In envelopes of such stars, convective luminosity is not so dominan…
Analysis of strange-mode instability with time-dependent convection in hot massive stars
Takafumi Sonoi, Hiromoto Shibahashi
We carry out nonadiabatic analysis of strange-modes in hot massive stars with time-dependent convection (TDC) for the first time. Although convective luminosity in envelopes of hot…
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…
