Quasi-periodic oscillations detected in a long-period eclipsing dwarf nova

Using NASA's Transiting Exoplanet Survey Satellite (TESS), Chinese astronomers have detected quasi-periodic oscillations (QPOs) in the light curve of HS 2325+8205--a long-period eclipsing dwarf nova. The discovery was detailed in the January 2023 issue of Monthly Notices of the Royal Astronomical Society.
