The radius and mass of the close solar twin 18 Sco derived from asteroseismology and interferometry [PDF]

open access: yes, 2010
The growing interest in solar twins is motivated by the possibility of comparing them directly to the Sun. To carry on this kind of analysis, we need to know their physical characteristics with precision.

Probing the internal magnetism of stars using asymptotic magneto-asteroseismology [PDF]

open access: yesAstronomy & Astrophysics, 2020
Context. Our knowledge of the dynamics of stars has undergone a revolution through the simultaneous large amount of high-quality photometric observations collected by space-based asteroseismology and ground-based high-precision spectropolarimetry.

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.

Asteroseismology of Solar-Type and Red-Giant Stars

open access: yes, 2013
We are entering a golden era for stellar physics driven by satellite and telescope observations of unprecedented quality and scope. New insights on stellar evolution and stellar interiors physics are being made possible by asteroseismology, the study of ...

Testing asteroseismology with Gaia DR2: hierarchical models of the Red Clump [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2019
Asteroseismology provides fundamental stellar parameters independent of distance, but subject to systematics under calibration. Gaia DR2 has provided parallaxes for a billion stars, which are offset by a parallax zero-point.

Precision Stellar Astrophysics in the Kepler Era

open access: yes, 2016
The study of fundamental properties (such as temperatures, radii, masses, and ages) and interior processes (such as convection and angular momentum transport) of stars has implications on various topics in astrophysics, ranging from the evolution of ...

Asteroseismology with COROT [PDF]

open access: yesInternational Astronomical Union Colloquium, 2004
AbstractThe COROT project has been developed in the framework of the CNES small satellite programme, with European and Brazilian cooperation. It will be launched in 2006. It is dedicated to seismology and detection of telluric planets. It will perform relative broad-band photometry in visible light during very long (150 d) observing runs in the same ...

Editorial: The Future of Asteroseismology

open access: yesFrontiers in Astronomy and Space Sciences, 2021
Rapid progress in the field of asteroseismology continues to be propelled by data from space missions. Since the time that this special topic was proposed in early 2017, the NASA Kepler/K2 missions have ended (November 2018) and the Canadian MOST ...

Inversions of Stellar Structure From Asteroseismic Data

open access: yesFrontiers 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.
