Asteroseismology and interferometry of the F7V spectroscopic binary Draconis A in the TESS CVZ

Jonatan Rudrasingam, Mikkel N. Lund, Frank Grundahl +26

We present a detailed analysis of the asteroseismic main-sequence benchmark star Dra A in the TESS northern CVZ. We aim to derive stellar mass and radius from asteroseismic mod…

A Test of Substellar Evolutionary Models with High-Precision Ages from Asteroseismology and Gyrochronology for the Benchmark System HR 7672AB

Yaguang Li, Michael C. Liu, Trent J. Dupuy +35

We present high-precision measurements for HR~7672AB, composed of a Sun-like (G0V) star and an L~dwarf companion. Three nights of precise (70 cm/s) radial velocity (RV) asteroseism…

Glitch analysis and asteroseismic modelling of subgiant Herculis: confirming and interpreting the peak as the helium glitch

Advik Gupta, Kuldeep Verma, Hans Kjeldsen +7

The measurements of pressure-mode and mixed-mode oscillation frequencies in subgiant stars offer a unique opportunity to probe their internal structures -- from the surface to the…

Coupling 1D stellar evolution with 3D-hydrodynamical simulations on-the-fly III: stellar evolution at different metallicities

Yixiao Zhou, Jakob L. Rørsted, Achim Weiss +10

A major weakness in one-dimensional (1D) stellar structure and evolution modeling is the simplified treatment of convection, which leads to erroneous near-surface stratification an…

Pushing the boundaries of asteroseismic individual frequency modelling: unveiling two evolved very-low metallicity red giants

Jens R. Larsen, Jakob L. Rørsted, Victor Aguirre Børsen-Koch +21

Metal-poor stars are key to understanding the first stellar generation in the Galaxy. Asteroseismic characterisation of red giants has traditionally relied on global seismic parame…

Realising efficient computation of individual frequencies for red-giant models

Jens R. Larsen, Jørgen Christensen-Dalsgaard, Mia S. Lundkvist +3

In order to improve the asteroseismic modelling efforts for red-giant stars, the numerical computation of theoretical individual oscillation modes for evolved red-giant models has…

Asteroseismology and Spectropolarimetry of the Exoplanet Host Star Serpentis

Travis S. Metcalfe, Derek Buzasi, Daniel Huber +31

The bright star Ser hosts a hot Neptune with a minimum mass of 13.6 and a 15.5 day orbit. It also appears to be a solar analog, with a mean rotation period of 25.8 d…

Did Kepler-444 have a long-lived convective core?

Mark Lykke Winther, Víctor Aguirre Børsen-Koch, Jakob Lysgaard Rørsted +2

With the greater power to infer the state of stellar interiors provided by asteroseismology, it has become possible to study the survival of initially convective cores within stars…

Advanced asteroseismic modelling: breaking the degeneracy between stellar mass and initial helium abundance

Kuldeep Verma, Jakob L. Rørsted, Aldo M. Serenelli +3

Current stellar model predictions of adiabatic oscillation frequencies differ significantly from the corresponding observed frequencies due to the non-adiabatic and poorly understo…

TESS Asteroseismology of Mensae: Benchmark Ages for a G7 Dwarf and its M-dwarf Companion

Ashley Chontos, Daniel Huber, Travis A. Berger +27

Asteroseismology of bright stars has become increasingly important as a method to determine fundamental properties (in particular ages) of stars. The Kepler Space Telescope initiat…

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…
