Hierarchical fragmentation in the Perseus molecular cloud: From the cloud scale to protostellar objects
Riwaj Pokhrel, Philip C. Myers, Michael M. Dunham +8
We present a study of hierarchical structure in the Perseus molecular cloud, from the scale of the entire cloud (10 pc) to smaller clumps (1 pc), cores (0.05-0…
Intensity-Corrected Herschel Observations of Nearby Isolated Low-Mass Clouds
Sarah I. Sadavoy, Eric Keto, Tyler L. Bourke +8
We present intensity-corrected Herschel maps at 100 um, 160 um, 250 um, 350 um, and 500 um for 56 isolated low-mass clouds. We determine the zero-point corrections for Herschel PAC…
The VLA Nascent Disk And Multiplicity Survey of Perseus Protostars (VANDAM). III. Extended Radio Emission from Protostars in Perseus
Łukasz Tychoniec, John J. Tobin, Agata Karska +8
Centimeter continuum emission from protostars offers insight into the innermost part of the outflows, as shock-ionized gas produces free-free emission. We observed a complete popul…
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.…
A turbulent origin for the complex envelope kinematics in the young low-mass core Per-Bolo 58
Maria Jose Maureira, Hector G. Arce, Stella S. R. Offner +5
We use CARMA 3mm continuum and molecular lines (NH2D, N2H+, HCO+, HCN and CS) at ~1000 au resolution to characterize the structure and kinematics of the envelope surrounding the de…
How do stars gain their mass? A JCMT/SCUBA-2 Transient Survey of Protostars in Nearby Star Forming Regions
Gregory J. Herczeg, Doug Johnstone, Steve Mairs +55
Most protostars have luminosities that are fainter than expected from steady accretion over the protostellar lifetime. The solution to this problem may lie in episodic mass accreti…
