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…
