A 1.3 mm SMA Survey of 29 Variable Young Stellar Objects
Hauyu Baobab Liu, Michael M. Dunham, Ilaria Pascucci +16
Young stellar objects (YSOs) may undergo periods of active accretion (outbursts), during which the protostellar accretion rate is temporarily enhanced by a few orders of magnitude.…
Vortex stretching in self-gravitating protoplanetary discs
Zs. Regaly, E. Vorobyov
Horseshoe-shaped brightness asymmetries of several transitional discs are thought to be caused by large-scale vortices. Anticyclonic vortices are efficiently collect dust particles…
Formation of freely floating sub-stellar objects via close encounters
Eduard I. Vorobyov, Maria Steinrueck, Vardan Elbakyan +1
We numerically studied close encounters between a young stellar system hosting a massive, gravitationally fragmenting disk and an intruder diskless star with the purpose to determi…
Mass transport from the envelope to the disk of V346 Nor: a case study for the luminosity problem in an FUor-type young eruptive star
Á. Kóspál, P. Ábrahám, T. Csengeri +7
A long-standing open issue of the paradigm of low-mass star formation is the luminosity problem: most protostars are less luminous than theoretically predicted. One possible soluti…
Alignment Between Protostellar Outflows and Filamentary Structure
Ian W. Stephens, Michael M. Dunham, Philip C. Myers +13
We present new Submillimeter Array (SMA) observations of CO(2-1) outflows toward young, embedded protostars in the Perseus molecular cloud as part of the Mass Assembly of Stellar S…
The effect of accretion on the pre-main-sequence evolution of low-mass stars and brown dwarfs
Eduard Vorobyov, Vardan Elbakyan, Takashi Hosokawa +3
The pre-main-sequence evolution of low-mass stars and brown dwarfs is studied numerically starting from the formation of a protostellar/proto-brown dwarf seed and taking into accou…
