The nature of very low luminosity objects (VeLLOs)
Eduard I. Vorobyov, Vardan Elbakyan, Michael Dunham +1
The nature of very low luminosity objects with the internal luminosity L_obj <= 0.1 Lsun is investigated by means of numerical modeling coupling the core collapse simulations with…
Kinematics of a young low-mass star forming core: Understanding the evolutionary state of the First Core Candidate L1451-mm
Maria Jose Maureira, Hector Arce, Michael M. Dunham +4
We use 3mm multi-line and continuum CARMA observations towards the first hydrostatic core (FHSC) candidate L1451-mm to characterize the envelope kinematics at 1000 AU scales and in…
A Triple Protostar System Formed via Fragmentation of a Gravitationally Unstable Disk
John Tobin, Kaitlin Kratter, Magnus Persson +9
Binary and multiple star systems are a frequent outcome of the star formation process, and as a result, almost half of all sun-like stars have at least one companion star. Theoreti…
Cygnus X-3: Its Little Friend's Counterpart, the Distance to Cygnus X-3, and Outflows/Jets
Michael McCollough, Lia Corrales, Michael Dunham
Chandra observations have revealed a feature,within 16" of Cygnus X-3 which varied in phase with Cygnus X-3. This feature was shown to be a Bok globule which is along the line of s…
Multi-wavelength study of the low-luminosity outbursting young star HBC 722
Á. Kóspál, P. Ábrahám, J. A. Acosta-Pulido +22
HBC 722 (V2493 Cyg) is a young eruptive star in outburst since 2010. It is an FU Orionis-type object with an atypically low outburst luminosity. Because it was well characterized i…
Imaging the water-snow line during a protostellar outburst
Lucas A. Cieza, Simon Casassus, John Tobin +13
A snow-line is the region of a protoplanetary disk at which a major volatile, such as water or carbon monoxide, reaches its condensation temperature. Snow-lines play a crucial role…
