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

Astronomy & 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.

A Gravitational-Wave Perspective on Neutron-Star Seismology

Universe, 2021
We provide a bird’s-eye view of neutron-star seismology, which aims to probe the extreme physics associated with these objects, in the context of gravitational-wave astronomy.

Asteroseismology with Small Telescopes [PDF]

Symposium - 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.

Asymptotic power spectra and visibilities of damped mixed modes

Astronomy & Astrophysics
Recent observational studies of red giant stars have estimated the visibility of their mixed oscillation modes, which is a proxy of the average energy of these modes.

Current issues in asteroseismology

Journal 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]

, 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.

Isochrone-cloud fitting and asteroseismology of the Kepler open cluster NGC 6866

Astronomy & Astrophysics
Context. Isochrone fitting is a classical method used to determine the ages of open clusters. However, the derived ages depend strongly on the chosen input physics of the stellar models used to deduce the isochrones.

On the Nature of the Core of α Centauri A: The Impact of the Metallicity Mixture

Frontiers in Astronomy and Space Sciences, 2019
Forward asteroseismic modeling plays an important role toward a complete understanding of the physics taking place in deep stellar interiors. With a dynamical mass in the range over which models develop convective cores while in the main sequence, the ...

Inversions of Stellar Structure From Asteroseismic Data

Frontiers in Astronomy and Space Sciences, 2022
The advent of space-based photometry missions in the early 21st century enabled the application to asteroseismic data of advanced inference techniques until then restricted to the field of helioseismology.

The CubeSpec space mission

Astronomy & Astrophysics
Context. Massive stars play a central role in astrophysics, yet their internal structure remains poorly constrained due to uncertainties regarding their core masses, internal rotation, and chemical mixing.
