Aims. This work is dedicated to a search for new pulsating hot subdwarfs in TESS photometric data which could have been missed in previous searches. Methods. By matching catalogues of hot subdwarfs with TESS targets and using luminosities from Gaia parallaxes, a list of 1389 candidate hot subdwarfs observed by TESS was created. The periodograms of these stars were inspected, and the stars were classified according to variability type. Results. An updated catalogue of all known pulsating hot…

A search for hot subdwarf binaries in data from the Transiting Exoplanet Survey Satellite

We present the results of a search for binary hot subdwarf stars in photometric data from the Transiting Exoplanet Survey Satellite (TESS). The sample of objects used in this work was a byproduct

Pulse Timing Discovery of a Three-day Companion to the Hot Subdwarf BPM 36430

Hot subdwarf B stars are core-helium-burning objects that have undergone envelope stripping, likely by a binary companion. Using high-speed photometry from the Transiting Exoplanet Survey Satellite,
