Super-Nyquist asteroseismology with the Kepler Space Telescope

, 2013
Barycentric corrections made to the timing of Kepler observations, necessitated by variations in light arrival time at the satellite, break the regular time-sampling of the data -- the time stamps are periodically modulated. A consequence is that Nyquist

Stellar Ages of TESS Stars, Adopting Spectroscopic Data from Gaia GSP-Spec

Galaxies
The Gaia DR3 GSP-spec/TESS (GST) catalog combines asteroseismic data from NASA’s TESS mission with spectroscopic data from ESA’s Gaia mission, and contains about 116,000 Red Clump and Red Giant Branch stars, surpassing previous datasets in size and ...

The potential for super-Nyquist asteroseismology with TESS

, 2015
The perfect 30-min cadence of the full-frame images from the Transiting Exoplanet Survey Satellite (TESS) will impose a hard Nyquist limit of 24 d-1 (≈278 μHz).

The revolutionary breakthroughs and remaining bottlenecks of accurate astrometric asteroseismology

, 2022
<p>Asteroseismology and Gaia astrometry have both revolutionized astronomy thanks to the precise stellar radii and masses that they provide, which benefit studies of exoplanets, Galactic archaeology, and stellar physics.

Precise Parameter Determination of the Open Cluster NGC 1647 via Asteroseismology of p-mode Pulsators

The Astrophysical Journal
Asteroseismology of member pulsators provides a robust physical constraint on cluster parameters by linking internal stellar structures to the global properties of the host cluster.

Helioseismology, Asteroseismology, and MHD Connections

, 2008
This volume presents a timely snapshot of the state of helio- and asteroseismology in the era when the SOHO/MDI instrument is about to be replaced by SDO/HMI and the CoRoT space mission is yielding its first long-duration light curves of thousands of ...
