(Abridged). We introduce the Aarhus Red Giants Challenge, a series of detailed comparisons between widely used stellar evolution and oscillation codes aiming at establishing the mi…
A seismic scaling relation for stellar age II: The red giant branch
Earl Patrick Bellinger
Owing to their simplicity and ease of application, seismic scaling relations are widely used to determine the properties of stars exhibiting solar-like oscillations, such as solar…
Properties of OB star-black hole systems derived from detailed binary evolution models
N. Langer, C. Schürmann, K. Stoll +38
The recent gravitational wave measurements have demonstrated the existence of stellar mass black hole binaries. It is essential for our understanding of massive star evolution to i…
Detection and characterisation of oscillating red giants: first results from the TESS satellite
Víctor Silva Aguirre, Dennis Stello, Amalie Stokholm +78
Since the onset of the `space revolution' of high-precision high-cadence photometry, asteroseismology has been demonstrated as a powerful tool for informing Galactic archaeology in…
When a Period Is Not a Full Stop: Light Curve Structure Reveals Fundamental Parameters of Cepheid and RR Lyrae Stars
Earl P. Bellinger, Shashi M. Kanbur, Anupam Bhardwaj +1
The period of pulsation and the structure of the light curve for Cepheid and RR Lyrae variables depend on the fundamental parameters of the star: mass, radius, luminosity, and effe…

We compare radii based on parallaxes to asteroseismic scaling relation-based radii of dwarfs subgiants and first-ascent giants from the ${\…
Asteroseismology of the Multiplanet System K2-93
Mikkel N. Lund, Emil Knudstrup, Victor Silva Aguirre +14
We revisit the analysis of the bright multiplanet system K2-93, discovered with data taken by the K2 mission. This system contains five identified planets ranging in size from sub-…
gamma Cas stars: Normal Be stars with disks impacted by the wind of a helium-star companion?
N. Langer, D. Baade, J. Bodensteiner +4
Cas stars are a 1% minority among classical Be stars with hard but only moderately strong continuous thermal X-ray flux and mostly very early-B spectral type. The X-ray f…
TESS first look at evolved compact pulsators : Discovery and asteroseismic probing of the g-mode hot B subdwarf pulsator EC 21494-7018
S. Charpinet, P. Brassard, G. Fontaine +29
We present the discovery and asteroseismic analysis of a new g-mode hot B subdwarf (sdB) pulsator, EC 21494-7018 (TIC 278659026), monitored in TESS first sector using 120-second ca…
Chromospheric emission of solar-type stars with asteroseismic ages
R S Booth, K. Poppenhaeger, C. A. Watson +3
Stellar magnetic activity decays over the main-sequence life of cool stars due to the stellar spin-down driven by magnetic braking. The evolution of chromospheric emission is well-…
Coupling 1D stellar evolution with 3D-hydrodynamical simulations on-the-fly II: Stellar Evolution and Asteroseismic Applications
Jakob Rørsted Mosumgaard, Andreas Christ Sølvsten Jørgensen, Achim Weiss +2
Models of stellar structure and evolution are an indispensable tool in astrophysics, yet they are known to incorrectly reproduce the outer convective layers of stars. In the first…
Gravity-mode period spacings and near-core rotation rates of 611 Doradus stars with \textit{Kepler}
Gang Li, Timothy Van Reeth, Timothy R. Bedding +4
We report our survey of \,Doradus stars from the 4-yr \textit{Kepler} mission. These stars pulsate mainly in g modes and r modes, showing period-spacing patterns in the amplitud…
TESS first look at evolved compact pulsators: asteroseismology of the pulsating helium-atmosphere white dwarf TIC 257459955
Keaton J. Bell, Alejandro H. Córsico, Agnès Bischoff-Kim +10
Pulsation frequencies reveal the interior structures of white dwarf stars, shedding light on the properties of these compact objects that represent the final evolutionary stage of…
Observational constraints on the origin of the elements II. 3D non-LTE formation of Ba ii lines in the solar atmosphere
A. J. Gallagher, M. Bergemann, R. Collet +5
Context. The pursuit of more realistic spectroscopic modelling and consistent abundances has led us to begin a new series of papers designed to improve current solar and stellar ab…
Testing stellar evolution with asteroseismic inversions of a main sequence star harboring a small convective core
Earl P. Bellinger, Sarbani Basu, Saskia Hekker +1
The goal of stellar evolution theory is to predict the structure of stars throughout their lifetimes. Usually, these predictions can be assessed only indirectly, for example by com…
The first view of Scuti and Doradus stars with the TESS mission
V. Antoci, M. S. Cunha, D. M. Bowman +63
We present the first asteroseismic results for Scuti and Doradus stars observed in Sectors 1 and 2 of the TESS mission. We utilise the 2-min cadence TESS data for a sample…
