Asteroseismic Analysis of the Merger Product Red Giant in the Persei System
Rozália Z. Ãdám, László Molnár, Róbert Szabó +7
Context. Persei is a long-period eclipsing binary system ( years) containing a red giant primary, and it is well known for its multi-faceted classification as a…
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…
Short- and long-term variations of the high mass accretion rate classical T Tauri star DR Tau
Gabriella Zsidi, Ãgnes Kóspál, Péter Ãbrahám +20
Classical T Tauri stars are newly formed, low mass stars which may display both periodic and random variations in their brightness. The interaction between the star and its circums…
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…
A theoretical framework for BL Her stars IV. New period-luminosity relations in the Rubin-LSST filters
Susmita Das, László Molnár, Róbert Szabó +5
We present new theoretical light curves in the Rubin-LSST filters for a fine grid of BL Her models computed using MESA-RSP. We also derive new theoretical period-luminosity (PL) an…
