Global asteroseismology of 19,000 red giants in the TESS Continuous Viewing Zones
K. R. Sreenivas, Timothy R. Bedding, Daniel Huber +5
TESS (Transiting Exoplanet Survey Satellite) has produced long-term photometry for millions of stars across the sky. In this work, we present an asteroseismic catalogue of 19,151 r…
Optical spectroscopic signatures of the red giant evolutionary state
Ella Xi Wang, Melissa Ness, Thomas Nordlander +17
Modern spectroscopic surveys output large data volumes. Theoretical models provide a means to transform the information encoded in these data to measurements of physical stellar pr…
Asteroseismology of the G8 subgiant beta Aquilae with SONG-Tenerife, SONG-Australia and TESS
Hans Kjeldsen, Timothy R. Bedding, Yaguang Li +28
We present time-series radial velocities of the G8 subgiant star beta Aql obtained in 2022 and 2023 using SONG-Tenerife and, for the first time, SONG-Australia. We also analyse a s…
Acoustic modes in M67 cluster stars trace deepening convective envelopes
Claudia Reyes, Dennis Stello, Joel Ong +3
Acoustic oscillations in stars are sensitive to stellar interiors. Frequency differences between overtone modes -- large separations -- probe stellar density, while differences bet…
Asteroseismic Study of Subgiants and Giants of the Open Cluster M67 using Kepler/K2: Expanded Sample and Precise Masses
Claudia Reyes, Dennis Stello, Marc Hon +7
Sparked by the asteroseismic space revolution, ensemble studies have been used to produce empirical relations linking observed seismic properties and fundamental stellar properties…
Modeling Asteroseismic Yields for the Roman Galactic Bulge Time-Domain Survey
Trevor J. Weiss, Noah J. Downing, Marc H. Pinsonneault +10
The Galactic Bulge Time Domain Survey (GBTDS) of the Roman Space Telescope will take high cadence data of the Galactic bulge. We investigate the asteroseismic potential of this sur…
Resolving an Asteroseismic Catastrophe: Structural Diagnostics from p-mode Phase Functions off the Main Sequence
J. M. Joel Ong, Christopher J. Lindsay, Claudia Reyes +2
On the main sequence, the asteroseismic small frequency separation between radial and quadrupole p-modes is customarily interpreted to be a direct diagnostic of internal…
APOKASC-3: The Third Joint Spectroscopic and Asteroseismic catalog for Evolved Stars in the Kepler Fields
Marc H. Pinsonneault, Joel C. Zinn, Jamie Tayar +38
In the third APOKASC catalog, we present data for the complete sample of 15,808 evolved stars with APOGEE spectroscopic parameters and Kepler asteroseismology. We used ten independ…
Benchmarking the spectroscopic masses of 249 evolved stars using asteroseismology with TESS
Sai Prathyusha Malla, Dennis Stello, Benjamin T. Monet +5
One way to understand planet formation is through studying the correlations between planet occurrence rates and stellar mass. However, measuring stellar mass in the red giant regim…
Isochrone fitting to the open cluster M67 in the era of Gaia and improved model physics
Claudia Reyes, Dennis Stello, Marc Hon +3
The Gaia mission has provided highly accurate observations that have significantly reduced the scatter in the colour-magnitude diagrams of open clusters. As a result of the improve…
The role of carbon in red giant spectro-seismology
Kirsten A. Banks, Sarah L. Martell, C. G. Tinney +6
Although red clump stars function as reliable standard candles, their surface characteristics (i.e. , , and [Fe/H]) overlap with those of red giant branch sta…
