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 across the Hertzsprung–Russell diagram

DW Kurtz - Annual Review of Astronomy and Astrophysics, 2022 - annualreviews.org
Asteroseismology has grown from its beginnings three decades ago to a mature field
teeming with discoveries and applications. This phenomenal growth has been enabled by …

Slowing the spins of stellar cores

J Fuller, AL Piro, AS Jermyn - Monthly Notices of the Royal …, 2019 - academic.oup.com
The angular momentum (AM) evolution of stellar interiors, along with the resulting rotation
rates of stellar remnants, remains poorly understood. Asteroseismic measurements of red …

Angular momentum transport in stellar interiors

C Aerts, S Mathis, TM Rogers - Annual Review of Astronomy …, 2019 - annualreviews.org
Stars lose a significant amount of angular momentum between birth and death, implying that
efficient processes transporting it from the core to the surface are active. Space …

Gaia-derived luminosities of Kepler A/F stars and the pulsator fraction across the δ Scuti instability strip

SJ Murphy, D Hey, T Van Reeth… - Monthly Notices of the …, 2019 - academic.oup.com
We study the fraction of stars in and around the δ Scuti instability strip that are pulsating,
using Gaia DR2 parallaxes to derive precise luminosities. We classify a sample of over 15 …

Interior rotation of a sample of γ Doradus stars from ensemble modelling of their gravity-mode period spacings

T Van Reeth, A Tkachenko, C Aerts - Astronomy & Astrophysics, 2016 - aanda.org
Context. Gamma Doradus stars (hereafter γ Dor stars) are known to exhibit gravity-and/or
gravito-intertial modes that probe the inner stellar region near the convective core boundary …

Gravity-mode period spacings and near-core rotation rates of 611 γ Doradus stars with Kepler

G Li, T Van Reeth, TR Bedding… - Monthly Notices of …, 2020 - academic.oup.com
We report our survey of γ Dor stars from the 4-yr Kepler mission. These stars pulsate mainly
in g modes and r modes, showing period-spacing patterns in the amplitude spectra. The …

The first view of δ Scuti and γ Doradus stars with the TESS mission

V Antoci, MS Cunha, DM Bowman… - Monthly Notices of …, 2019 - academic.oup.com
We present the first asteroseismic results for δ Scuti and γ Doradus stars observed in
Sectors 1 and 2 of the TESS mission. We utilize the 2-min cadence TESS data for a sample …

Sub-inertial gravity modes in the B8V star KIC 7760680 reveal moderate core overshooting and low vertical diffusive mixing

E Moravveji, RHD Townsend, C Aerts… - The Astrophysical …, 2016 - iopscience.iop.org
Thus far, KIC 7760680 is the richest slowly pulsating B star, exhibiting 36 consecutive dipole
(ℓ= 1) gravity (g-) modes. The monotonically decreasing period spacing of the series, in …

Characterizing the observational properties of δ Sct stars in the era of space photometry from the Kepler mission

DM Bowman, DW Kurtz - Monthly Notices of the Royal …, 2018 - academic.oup.com
The δ Sct stars are a diverse group of intermediate-mass pulsating stars located on and near
the main sequence within the classical instability strip in the Hertzsprung–Russell diagram …
