Discovery of new TESS pulsating hot subdwarfs

Astronomy and Astrophysics, 2022
This work is dedicated to a search for new pulsating hot subdwarfs in TESS photometric data which could have been missed in previous searches. By matching catalogues of hot subdwarfs with TESS targets and using luminosities from Gaia parallaxes, a list ...

A spectroscopic and proper motion search of Sloan Digital Sky Survey: red subdwarfs in binary systems [PDF]

Monthly Notices of the Royal Astronomical Society, 2013
Red subdwarfs in binary systems are crucial for both model calibration and spectral classification. We search for red subdwarfs in binary systems from a sample of high proper motion objects with Sloan Digital Sky Survey spectroscopy.
