Animation of pulsating star

Animation of a new type of pulsating star whose brightness oscillates over only one of the star's hemispheres. The unusual behavior of the star was first noticed by citizen scientists inspecting data from NASA’s Transiting Exoplanet Survey Satellite (TESS). The star is in a binary system and the gravitation pull of its companion star distorts its oscillations, according to an international team of astronomers.
