Mid-infrared time-domain study of recent dust production events in the extreme debris disc of TYC 4209-1322-1
A. Moór, P. Ábrahám, Á. Kóspál +23
Extreme debris discs are characterized by unusually strong mid-infrared excess emission, which often proves to be variable. The warm dust in these discs is of transient nature and…
Accretion and extinction variations in the low-mass pre-main sequence binary system WX Cha
Eleonora Fiorellino, Gabriella Zsidi, Agnes Kospal +5
Light curves of young star systems show photometric variability due to different kinematic, and physical processes. One of the main contributors to the photometric variability is t…
A gap at 1 au in the disk of DI Cha A revealed by infrared interferometry
Tímea Juhász, Péter Ábrahám, Attila Moór +6
DI Cha A is K0-type pre-main sequence star, the brightest component of a quadruple stellar system. Here we report on a detailed study of this star based on archival VLTI/MIDI and V…
PENELLOPE III. The peculiar accretion variability of XX Cha and its impact on the observed spread of accretion rates
R. A. B. Claes, C. F. Manara, R. Garcia-Lopez +17
The processes regulating protoplanetary disk evolution are constrained by studying how mass accretion rates scale with stellar and disk properties. The spread in these relations ca…
Accretion variability of the multiple T Tauri system VW Cha
Gabriella Zsidi, Eleonora Fiorellino, Ágnes Kóspál +5
Classical T Tauri stars are low-mass objects, which are still accreting material from the surrounding circumstellar disk. The accretion process is essential in the formation of Sun…
Accretion variability from minutes to decade timescales in the classical T Tauri star CR Cha
G. Zsidi, C. F. Manara, Á. Kóspál +6
Classical T Tauri stars are surrounded by a circumstellar disk from which they are accreting material. This process is essential in the formation of Sun-like stars. Although often…
