Radiative Transfer modeling of EC 53: An Episodically Accreting Class I Young Stellar Object
Giseon Baek, Benjamin A. MacFarlane, Jeong-Eun Lee +8
In the episodic accretion scenario, a large fraction of the protostellar mass accretes during repeated and large bursts of accretion. Since outbursts on protostars are typically id…
Observational signatures of outbursting protostars -- II: Exploring a wide range of eruptive protostars
Benjamin MacFarlane, Dimitris Stamatellos, Doug Johnstone +5
Young stars exhibit variability due to changes in the gas accretion rate onto them, an effect that should be quite significant in the early stages of their formation. As protostars…
Observational signatures of outbursting protostars - I: From hydrodynamic simulations to observations
Benjamin MacFarlane, Dimitris Stamatellos, Doug Johnstone +5
Accretion onto protostars may occur in sharp bursts. Accretion bursts during the embedded phase of young protostars are probably most intense, but can only be inferred indirectly t…
Compressed magnetic field in the magnetically-regulated global collapsing clump of G9.62+0.19
Tie Liu, Kee-Tae Kim, Sheng-Yuan Liu +22
How stellar feedback from high-mass stars (e.g., H{\sc ii} regions) influences the surrounding interstellar medium and regulates new star formation is still unclear. To address thi…
The JCMT Transient Survey: Stochastic and Secular Variability of Protostars and Disks In the Sub-Millimeter Observed Over Eighteen Months
Doug Johnstone, Gregory J. Herczeg, Steve Mairs +18
We analyze results from the first eighteen months of monthly sub-mm monitoring of eight star-forming regions in the JCMT Transient Survey. In our search for stochastic variability…
The JCMT Transient Survey: Identifying Submillimetre Continuum Variability over Several Year Timescales Using Archival JCMT Gould Belt Survey Observations
Steve Mairs, Doug Johnstone, Helen Kirk +19
Investigating variability at the earliest stages of low-mass star formation is fundamental in understanding how a protostar assembles mass. While many simulations of protostellar d…
The JCMT Transient Survey: Detection of sub-mm variability in a Class I protostar EC 53 in Serpens Main
Hyunju Yoo, Jeong-Eun Lee, Steve Mairs +6
During the protostellar phase of stellar evolution, accretion onto the star is expected to be variable, but this suspected variability has been difficult to detect because protosta…
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…
IRAS 01202+6133 : A Possible Case of Protostellar Collapse Triggered by a Small HII Region
Sung-Ju Kang, C. R. Kerton
We present an analysis of HCO+ (J=3-2) and H13CO+ (J=3-2) observations of the massive (M ~ 20 Msun) submm/IR source IRAS 01202+6133 located on the periphery of the HII region KR 12…
