Detection and characterisation of binary asteroid candidates through stellar occultations
R. Lallemand, J. Desmars, B. Sicardy +256
Binary asteroids provide key access to fundamental parameters of Solar System remnants and planetary formations. However, the current knowledge of binary asteroids remains strongly…
Time-resolved protoplanetary disk physics in DQ Tau with JWST
Ã. Kóspál, P. Ãbrahám, V. V. Akimkin +17
Accretion variability is ubiquitous in YSOs. While large outbursts may strongly affect the disk, the effects of moderate bursts are less understood. We aim to study the physical re…
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…
