6 SCUTI STAR GX PEGASI: ADDITIONAL ANALYSIS

Autor: S. V. Repin, E. Michel, M. Auvergne, A. Baglin, M. J. Goupil, L. S. Gurin, Yu. O. Samoilova

Publikováno v: Odessa Astronomical Publications, Vol 9, Iss 0, Pp 112-113 (2017)

Three criteria of the periodicity are discussed in the paper and their properties are investigated. These criteria are applied to investigate the periodicity properties of a variable star GX Pegasi. A number of periodic components are extracted.

Coupling between turbulence and solar-like oscillations: A combined Lagrangian PDF/SPH approach

Autor: J. Philidet, K. Belkacem, M.-J. Goupil

Publikováno v: Astronomy & Astrophysics. 664:A164

The first paper of this series established a linear stochastic wave equation for solar-like p-modes, correctly taking the effect of turbulence thereon into account. In this second paper, we aim at deriving simultaneous expressions for the excitation

Astronomy and Astrophysics-A&A, EDP Sciences, 2021, 656, pp.A95. ⟨10.1051/0004-6361/202141483⟩

Aims. This series of papers aims at building a new formalism specifically tailored to study the impact of turbulence on the global modes of oscillation in solar-like stars. This first paper aims at deriving a linear wave equation that directly and co

Asteroseismology is a unique tool that can be used to study the interior of stars and hence deliver unique information for the studiy of stellar physics, stellar evolution, and Galactic archaeology. We aim to develop a simple model of the information

Helioseismology and asteroseismology of red giant stars have shown that the distribution of angular momentum in stellar interiors, and its evolution with time remains an open issue in stellar physics. Owing to the unprecedented quality of Kepler phot
