Parameters and Pulsation Constant of Cepheid [PDF]
Particles, 2023 The analysis of fifty empirical period-radius relations and forty-three empirical period-luminosity relations is performed for the Cepheids. It is found that most of these relations have significant systematic errors.

Interaction Between Convection and Pulsation [PDF]
Living Reviews in Solar Physics, 2015 This article reviews our current understanding of modelling convection dynamics in stars. Several semi-analytical time-dependent convection models have been proposed for pulsating one-dimensional stellar structures with different formulations for how the

THE ABUNDANCE OF HELIUM AND STELLAR PULSATION
Odessa Astronomical Publications, 2017 Radial gradient of relative amplitude of the light variation FV for galactic classical Cepheids is found. The gradient has different signs for two cases: P > 8d and P < 8d. For P > 8d the gradient is negative.

An overview of stellar pulsation theory [PDF]
Astrophysics and Space Science, 1993 AbstractIn this paper I will give overview of the stellar pulsation theory. Starting with basic equations I will discuss modal properties of oscillations and excitation mechanisms. I also mention briefly the effects of rotation.

Nonthermal X-Rays from Pulsation-driven Shocks in Cepheids
The Astrophysical Journal, 2023 Rapid X-ray phase-dependent flux enhancement in the archetype classical Cepheid star δ Cep was observed by XMM-Newton and Chandra. We jointly analyze thermal and nonthermal components of the time-resolved X-ray spectra prior to, during, and after the ...

The Calculation of Stellar Pulsation [PDF]
Reviews of Modern Physics, 1964 In this paper we report methods of computation which have been developed to provide a theoretical understanding of the RR Lyrae and Cepheid type pulsating stars. The results reported are intended to illuminate the methods of calculation and to provide insight into the physical processes in these stars.

RADIAL STELLAR PULSATION AND THREE-DIMENSIONAL CONVECTION. III. COMPARISON OF TWO-DIMENSIONAL AND THREE-DIMENSIONAL CONVECTION EFFECTS ON RADIAL PULSATION [PDF]
Astrophysical Journal, 2014 Publishers' Version/PDFWe have developed a multi-dimensional radiation hydrodynamics code to simulate the interaction of radial stellar pulsation and convection for full-amplitude pulsating models.

The Role of Opacities in Stellar Pulsation [PDF]
, 2018 We examine the role of opacities in stellar pulsation with reference to Cepheids and RR Lyraes, and examine the effect of augmented opacities on the theoretical pulsation light curves in key temperature ranges.

Reminiscence of a stellar pulsation theorist [PDF]
, 1989 The author started working in stellar pulsation theory in 1965. Since this time, we have studied the effects of improved radiative transfer and dynamic zoning on models of Cepheids, RR Lyrae, and W Virginis stars.
