Studying the surface effect in Procyon A as an F-type star

open access: yesAstronomy & Astrophysics
Context. Procyon A is an F-type main-sequence star in a binary system. It has been the subject of numerous ground-based and space-based observing campaigns, providing precise classical constraints, including a well-determined mass.

An overview of helio- and asteroseismology [PDF]

open access: yesSymposium - International Astronomical Union, 1988
The purpose of the present paper is to give an introduction to the nomenclature, and a few of the results, of helio- and asteroseismology. It is hoped that this may provide a useful background for the more specialized reviews, and the contributed papers, in these proceedings.

Asteroseismology from Dome C

open access: yes, 2007
This paper discusses the opportunities at Dome C for both photometric and spectroscopic asteroseismology. Dome C has two great advantages in this field: the first is the high percentage of superbly photometric skies; the second is the opportunity for ...

Toward a New Paradigm in the Analysis of Asteroseismic Lightcurves

open access: yesFrontiers in Astronomy and Space Sciences, 2020
This paper aims at being a provocative guide to the future of asteroseismology from the perspective of the analysis of time series, where the fundamentals of harmonic analysis are subjected to stress tests.

Core-envelope coupling of gravito-inertial waves in pre-main-sequence solar-type stars

open access: yesAstronomy & Astrophysics
The recent detection of solar equatorial Rossby waves has renewed interest in the study of gravito-inertial waves propagating in the convective envelope of solar-type stars.

Asteroseismology with Small Telescopes [PDF]

open access: yesSymposium - International Astronomical Union, 1986
Study of the solar interior through analysis of solar oscillations, a field now referred to as helioseismology, has generated interest in the development of asteroseismology, the study of the interior of pulsating stars through the analysis of their oscillations.

Seismic detection of core magnetic fields in red giants using the gravity offset

open access: yesAstronomy & Astrophysics
Context. Magnetic fields are known to efficiently redistribute angular momentum in stars. Recently, magnetic fields have been measured in the cores of red giant stars using asteroseismology, and it was shown that core magnetic fields, if unaccounted for,

White Dwarfs as Physics Laboratories: Lights and Shadows

open access: yesFrontiers in Astronomy and Space Sciences, 2022
The evolution of white dwarfs is essentially a gravothermal process of cooling in which the basic ingredients for predicting their evolution are well identified, although not always well understood. There are two independent ways to test the cooling rate.

Current issues in asteroseismology

open access: yesJournal of Physics: Conference Series, 2008
In this contribution we briefly review some of the current issues and promises for the future by asteroseismology. We are entering a new phase in this field driven by the wealth of data that has been collected and data that will soon be available for asteroseismology across the HR Diagram.

An asteroseismology explorer [PDF]

open access: yes, 2008
In response to a NASA opportunity, a proposal has been made to study the concept of an Asteroseismology Explorer (ASE). The goal of the ASE would be to measure solar-like oscillations on many (perhaps hundreds) of stars during a 1-year mission, including many members of open clusters.
