Exploring Low-Amplitude Variability in First Overtone Cepheids with TESS
E. Plachy, H. Netzel, A. Bódi
Classical Cepheid stars that pulsate in the first overtone radial mode often exhibit additional periodicities at the millimagnitude level. Extensive studies of the OGLE data of the…
Three fast-spinning medium-sized Hilda asteroids uncovered by TESS
Nóra Takács, Csaba Kiss, Róbert Szakáts +8
Hilda asteroids, which orbit in a 3:2 resonance with Jupiter, serve as key indicators of dynamical processes in the early solar system. Their spin rates, an important probe of thes…
Connections between the cycle-to-cycle light curve and O-C variations of the non-Blazhko RR Lyrae stars
J. M. BenkÅ, A. Bódi, E. Plachy +1
It has long been known that if the durations of the consecutive cycles of a pulsating star vary randomly, the O-C diagram could show quasi-periodic/irregular variations, even thoug…
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…
