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…
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…
The chemistry of episodic accretion in embedded objects. 2D radiation thermo-chemical models of the post-burst phase
Ch. Rab, V. Elbakyan, E. Vorobyov +7
Episodic accretion is an important process in the evolution of young stars and their environment. The observed strong luminosity bursts of young stellar objects likely have a long…
Protostellar accretion traced with chemistry. High resolution C18O and continuum observations towards deeply embedded protostars in Perseus
Søren Frimann, Jes K. Jørgensen, Michael M. Dunham +6
Context: Understanding how accretion proceeds is a key question of star formation, with important implications for both the physical and chemical evolution of young stellar objects…
A concordant scenario to explain FU Ori from deep centimeter and millimeter interferometric observations
Hauyu Baobab Liu, Eduard I. Vorobyov, Ruobing Dong +13
We resolved FU Ori at 29-37 GHz using the JVLA with 0.07 resolution, and performed the complementary JVLA 8-10 GHz observations, the SMA 224 GHz and 272 GHz observations,…
The circumstellar disk response to the motion of the host star
Zs. Regaly, E. Vorobyov
Grid-based hydrodynamics simulations of circumstellar disks are often performed in the curvilinear coordinate system, in which the center of the computational domain coincides with…
