Pulsational characteristics of mass accreting stars in close binary systems
A. Miszuda
TL;DR
This paper explores the pulsational properties of mass-accreting stars in close binary systems, focusing on how binarity and mass transfer influence stellar pulsations, contributing to the emerging field of tidal asteroseismology.
Contribution
It presents preliminary asteroseismic analysis of a 10 solar mass beta Cephei star model undergoing mass accretion, highlighting effects of binarity on pulsations.
Findings
Mass transfer affects pulsational frequencies.
Binarity influences stellar oscillation modes.
Preliminary results suggest new asteroseismic signatures.
Abstract
Eclipsing binaries with pulsating components are a distinct subclass of binaries, merging orbital and pulsational analyses. In recent years, that subclass led to the definition of a newly formed branch of tidal asteroseismology. While single-star pulsators are well understood, the effects of binarity and possible mass transfer on pulsational characteristics, particularly in mass-gaining stars, remain to be systematically explored. Here, I present preliminary results on the asteroseismic properties of a mass-accreting model for a 10 Cephei-type star
