Brightness and mass accretion rate evolution during the 2022 burst of EX~Lupi
F. Cruz-Sáenz de Miera, Á. Kóspál, P. Ábrahám +18
EX Lupi is the prototype by which EXor-type outbursts were defined. It has experienced multiple accretion-related bursts and outbursts throughout the last decades, whose study have…
JWST/MIRI Spectroscopy of the Disk of the Young Eruptive Star EX Lup in Quiescence
Ágnes Kóspál, Péter Ábrahám, Lindsey Diehl +7
EX Lup is a low-mass pre-main sequence star that occasionally shows accretion-related outbursts. Here, we present JWST/MIRI medium resolution spectroscopy obtained for EX Lup fourt…
Forbidden emission lines in protostellar outflows and jets with MUSE
Lizxandra Flores-Rivera, Mario Flock, Nicolás Kurtovic +14
Forbidden emission lines in protoplanetary disks are a key diagnostic in studies of the evolution of the disk and the host star. We report spatially resolved emission lines, [OI] 6…
