Probing the interior physics of stars through asteroseismology

C Aerts - Reviews of Modern Physics, 2021 - APS
Yearslong time series of high-precision brightness measurements have been assembled for
thousands of stars with telescopes operating in space. Such data have allowed astronomers …

Asteroseismology and interferometry

Catalogue and properties of δ Scuti stars in binaries

A Liakos, P Niarchos - Monthly Notices of the Royal …, 2016 - academic.oup.com
The catalogue contains 199 confirmed cases of binary systems containing at least one
pulsating component of δ Sct type. The sample is divided into subgroups in order to describe …

The period–luminosity relation for δ Scuti stars using Gaia DR2 parallaxes

E Ziaali, TR Bedding, SJ Murphy… - Monthly Notices of …, 2019 - academic.oup.com
We have examined the period–luminosity (P–L) relation for δ Scuti stars using Gaia DR2
