Using asteroseismology to characterise exoplanet host stars [PDF]
arXiv, 2018 The last decade has seen a revolution in the field of asteroseismology - the study of stellar pulsations. It has become a powerful method to precisely characterise exoplanet host stars, and as a consequence also the exoplanets themselves. This synergy between asteroseismology and exoplanet science has flourished in large part due to space missions such

Variability survey in the young open cluster IC 1805 [PDF]
, 2012 The variability survey in the young open cluster IC 1805 is a part of the ongoing program of searching for early-type variable stars in open clusters of the northern sky conducted in Wroclaw (see Jerzykiewicz et al. 2011 and references therein). We are particularly interested in pulsating stars such as beta Cephei and SPB.

Toward a New Paradigm in the Analysis of Asteroseismic Lightcurves
Frontiers 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.

Asteroseismology and spectropolarimetry: opening new windows on the internal dynamics of massive stars [PDF]
, 2014 In this article, we show how asteroseismology and spectropolarimetry allow to probe dynamical processes in massive star interiors. First, we give a summary of the state-of-the-art. Second, we recall the MHD mechanisms that take place in massive stars.

Asteroseismological Analysis of Rich Pulsating White Dwarfs [PDF]
AIP Conference Proceedings, Volume 1170, pp. 621-624 (2009), 2010 We present the results of the asteroseismological analysis of two rich DAVs, G38-29 and R808, recent targets of the Whole Earth Telescope. 20 periods between 413 s and 1089 s were found in G38-29's pulsation spectrum, while R808 is an even richer pulsator, with 24 periods between 404 s and 1144 s.

Asteroseismology of OB stars with hundreds of single snapshot spectra (and a few time-series of selected targets) [PDF]
, 2014 Imagine we could do asteroseismology of large samples of OB-type stars by using just one spectrum per target. That would be great! But this is probably a crazy and stupid idea. Or maybe not. Maybe we have the possibility to open a new window to investigate stellar oscillations in massive stars that has been in front of us for many years, but has not ...

White-Dwarf Asteroseismology With the Kepler Space Telescope
Frontiers in Astronomy and Space Sciences, 2020 In the course of their evolution, white-dwarf stars go through at least one phase of variability in which the global pulsations they undergo allow astronomers to peer into their interiors, making it possible to shed light on their deep inner structure ...

Asteroseismology of Exoplanet-Host Stars in the Kepler Era [PDF]
arXiv, 2015 New insights on stellar evolution and stellar interior physics are being made possible by asteroseismology, the study of stars by the observation of their natural, resonant oscillations. Asteroseismology is making significant contributions to our understanding of solar-type stars, in great part due to the exquisite data that have been made available by
