NONLINEAR ASTEROSEISMOLOGY OF RR LYRAE [PDF]

The Astrophysical Journal, 2012
The observations of the Kepler space telescope revealed that fundamental-mode RR Lyrae stars may show various radial overtones. The presence of multiple radial modes may allow us to conduct nonlinear asteroseismology: comparison of mode amplitudes and frequency shifts between observations and models.

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

Astronomy & 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 ...

The SAGA so far: reading the history of the Galaxy with asteroseismology

EPJ Web of Conferences, 2015
Asteroseismology has the capability of delivering stellar properties which would otherwise be inaccessible, such as radii, masses and thus ages of stars.

Asteroseismic inferences from the study of non-linearities in δ Sct stars

Frontiers in Astronomy and Space Sciences, 2022
Many pulsating star light curves must be interpreted strictly within the framework of a non-linear theory. The detection of non-linear interactions between pulsation modes has increased due to the ultra-precise photometric data provided by space missions.

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.

Asteroseismology of pulsating DA white dwarfs with fully evolutionary models

EPJ 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.

An Observer's View on the Future of Asteroseismology

Frontiers 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

Ensemble Asteroseismology with the TRILEGAL and the PARAM codes An estimate of the systematic errors introduced by stellar models [PDF]

, 2022
Asteroseismology has provided precise methods for stellar parameters estimation (e.g. mass, radius and age of stars). Our aim is to quantify systematic errors when the Bayesian method implemented in the PARAM code is applied with various input grids

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.
