Solar System objects observed with TESS -- Early Data Release 2: I. Spin-shape recovery potential of multi-epoch TESS observations

Nóra Takács, Csaba Kiss, Róbert Szakáts +1

Using multidirectional measurements from the Transiting Exoplanet Survey Satellite (TESS), we investigated the viability of determining the approximate shape and spin axis orientat…

Three fast-rotating Jovian Trojans identified by TESS set new population density limits

Csaba Kiss, Nóra Takács, Csilla E. Kalup +8

Here we report on the identification of the three fastest rotating Jovian Trojans with reliable population assignment, using light curve data from the Transiting Exoplanet Satellit…

Stellar flare morphology with TESS across the main sequence

Bálint Seli, Krisztián Vida, Katalin Oláh +5

Stellar flares are abundant in space photometric light curves. As they are now available in large enough numbers, the statistical study of their overall temporal morphology is time…
