On the question of multimode stellar pulsations [PDF]
Monthly Notices of the Royal Astronomical Society, 1986 Des observations recentes de cepheides, et naines blanches peuvent etre interpretees par la presence de jusqu'a cinq frequences reliees irrationnellement dans le spectre de puissance de leurs courbes de lumiere. A l'aide de modeles qualitatifs, on montre qu'un tel mouvement quasi periodique peut en fait se produire dans des regimes dissipatifs et non ...

Survey for δ Sct components in eclipsing binaries and new correlations between pulsation frequency and fundamental stellar characteristics [PDF]
, 2012 CCD observations of 68 eclipsing binary systems, candidates for containing δ Scuti components, were obtained. Their light curves are analysed using the period04 software for possible pulsational behaviour.

RADIAL STELLAR PULSATION AND THREE-DIMENSIONAL CONVECTION. I. NUMERICAL METHODS AND ADIABATIC TEST CASES [PDF]
, 2011 We are developing a three-dimensional radiation hydrodynamics code to simulate the interaction of convection and pulsation in classical variable stars. One key goal is the ability to carry these simulations to full amplitude in order to compare them with

On the Hydrodynamics of Stellar Pulsation and Stability [PDF]
International Astronomical Union Colloquium, 2002 AbstractMuch of our knowledge of the hydrodynamics of stellar oscillations is summarized in the now-classical article by Ledoux & Walraven in volume 51 of the Handbuch der Physik. It is from that article that I, and many others, first learned the subject.

Systematic search for stellar pulsators in the eclipsing binaries observed by Kepler [PDF]
Astronomy & Astrophysics, 2019 Eclipsing binaries (EBs) are unique targets for measuring precise stellar properties and can be used to constrain stellar evolution models. In particular, it is possible to measure masses and radii of both components of a double-lined spectroscopic EB at

The Astrophysical Journal, 2023 AllS single stars that are born with masses up to 8.5–10 M _⊙ will end their lives as white dwarf (WD) stars. In this evolutionary stage, WDs enter the cooling sequence, where the stars radiate away their thermal energy and are basically cooling.

Forward Asteroseismic Modeling of Stars with a Convective Core from Gravity-mode Oscillations: Parameter Estimation and Stellar Model Selection [PDF]
Astrophysical Journal Supplement Series, 2018 We propose a methodological framework to perform forward asteroseismic modeling of stars with a convective core, based on gravity-mode oscillations. These probe the near-core region in the deep stellar interior.

Dust Shells around OH/IR Stars [PDF]
Journal of Astronomy and Space Sciences, 1988 We have made new models for mass-losing OH/IR stars to explain the properties of the dust shells around them using more accurate information about the material in the shell and the physical processes including pulsations. We have applied our dust opacity

Observations of the pulsation of the Cepheid l Car with the Sydney University Stellar Interferometer [PDF]
, 2008 Observations of the southern Cepheid t Car to yield the mean angular diameter and angular pulsation amplitude have been made with the Sydney University Stellar Interferometer at a wavelength of 696 nm. The resulting mean limb-darkened angular diameter is
