Investigation of Superhumps in SU UMa-type Dwarf Novae Based on the Observations of TESS

The Astrophysical Journal, 2023
We report a superhumps analysis of seven SU UMa-type dwarf novae based on observations made by the Transiting Exoplanet Survey Satellite (TESS). Superhumps are seen during the superoutbursts of SU UMa-type dwarf novae. The monthlong data sets of TESS are
