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,

Bolometric corrections of stellar oscillation mode amplitudes as observed by the PLATO mission

open access: yesAstronomy & Astrophysics
Aims. We derive bolometric correction functions for oscillation mode amplitudes observed by the different cameras of the ESA PLATO mission. Such corrections between bolometric (full light) and mission instrument-specific amplitudes enable comparisons to ...

Asymptotic power spectra and visibilities of damped mixed modes

open access: yesAstronomy & 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.

Asteroseismology of pulsating DA white dwarfs with fully evolutionary models

open access: yesEPJ Web of Conferences, 2013
We present a new approach for asteroseismology of DA white dwarfs that consists in the employment of a large set of non-static, physically sound, fully evolutionary models representative of these stars.

The CubeSpec space mission

open access: yesAstronomy & 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.

An Observer's View on the Future of Asteroseismology

open access: yesFrontiers in Astronomy and Space Sciences, 2019
Scientific research is a continuous process, and the speed of future progress can be estimated by the pace of finding explanations for previous research questions. In this observer's based view of stellar pulsation and asteroseismology, we start with the

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 ...

Influence of Magnetic Activity on the Determination of Stellar Parameters Through Asteroseismology

open access: yesFrontiers in Astronomy and Space Sciences, 2019
Magnetic activity changes the gravito-acoustic modes of solar-like stars and in particular their frequencies. There is an angular-degree dependence that is believed to be caused by the non-spherical nature of the magnetic activity in the stellar ...

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

open access: yesAstronomy & 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.
