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 dominant as that in envelopes of stars in the redder side of the classical instability strip. Around the Fe opacity bump, however, convection non-negligibly contributes to energy transfer. Indeed, instability of modes excited at the Fe bump is likely to be suppressed with TDC compared with the case of adopting the frozen-in…

Nonadiabatic analysis of strange-modes in hot massive stars with time-dependent convection

We carry out nonadiabatic analysis of strange-modes in hot massive stars with time-dependent convection (TDC). We find that the instability of the modes excited at the Fe bump is weaker with TDC than

Instability, finite amplitude pulsation and mass-loss in models of massive OB-type stars

Variability and mass-loss are common phenomena in massive OB-type stars. It is argued that they are caused by violent strange mode instabilities identified in corresponding stellar models. We present

Progress and problems in massive star pulsation theory

Abstract Massive stars pulsate in various modes; radial and nonradial p-modes, g-modes, and strange modes including oscillatory convective (non-adiabatic g−) modes. Those modes are responsible for

Pulsations of pre-white dwarfs with hydrogen-dominated atmospheres

We carried out a fully non-adiabatic analysis for nonradial oscillations of pre-white dwarfs evolved from the post-Asymptotic Giant Branch (AGB) with hydrogen-dominated envelopes. It is shown that

Pulsations of red supergiant pair-instability supernova progenitors leading to extreme mass loss

Recent stellar evolution models show consistently that very massive metal-free stars evolve into red supergiants shortly before they explode. We argue that the envelopes of these stars, which will

Stellar oscillations. II The non-adiabatic case

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, which have been (and



Convection-pulsation coupling - II. Excitation and stabilization mechanisms in $\delta$ Sct and $\gamma$ Dor stars

We apply here the Time Dependent Convection (TDC) treatment presented in our earlier paper in this series to the study of δ  Sct and γ  Dor pulsating stars. Stabilization of the δ  Sct p-modes at the

The stability of massive stars and its dependence on metallicity and opacity

Following a similar investigation based on the of LAOL opacities, the stability of massive stars is re-examined using the latest available OPAL opacity tables. Two groups of dynamical strange-mode

The simulation of non-linear stellar pulsations

Details of a method for the numerical simulation of stellar pulsations and instabilities in the non-linear regime are presented. Important properties of the method are intrinsic mass and energy

Convection-pulsation coupling - I. A mixing-length perturbative theory

We present in details a time-dependent convection treatment in the frame of the Mixing-Length Theory (MLT). Following the original ideas by Unno (1967, PASJ, 19, 140), this theory has been developed

Turbulent convection and pulsational stability of variable stars — IV. The red edge of the δ Scuti instability strip

Using a non-local time-dependent statistical theory of convection, we made a linear pulsational instability analysis for stars in the mass range 1.4-3.0 M-circle dot. The results define a red edge

Forming the First Stars in the Universe: The Fragmentation of Primordial Gas

This work investigates the fragmentation properties of metal-free gas in the context of a hierarchical model of structure formation and finds that the gas dissipatively settles into a rotationally supported disk that has a very filamentary morphology.

The Formation of the First Star in the Universe

It is concluded that at most one massive metal-free star forms per pregalactic halo, consistent with recent abundance measurements of metal-poor galactic halo stars.

The Nucleosynthetic Signature of Population III

Growing evidence suggests that the first generation of stars may have been quite massive (~100-300 M☉). Could these stars have left a distinct nucleosynthetic signature? We explore the


We substantially update the capabilities of the open source software package Modules for Experiments in Stellar Astrophysics (MESA), and its one-dimensional stellar evolution module, MESAstar.

Periodic mass-loss episodes due to an oscillation mode with variable amplitude in the hot supergiant HD 50064

Aims. We aim to interpret the photometric and spectroscopic variability of the luminous blue variable supergiant HD 50064 ( V = 8.21). Methods. CoRoT space photometry and follow-up high-resolution
