The JCMT Transient Survey: Four Year Summary of Monitoring the Submillimeter Variability of Protostars
Yong-Hee Lee, Doug Johnstone, Jeong-Eun Lee +49
We present the four-year survey results of monthly submillimeter monitoring of eight nearby (pc) star-forming regions by the JCMT Transient Survey. We apply the Lomb-Scargl…
The Formation of Stars -- From Filaments to Cores to Protostars and Protoplanetry Disks
James Di Francesco, Helen Kirk, Doug Johnstone +16
Star formation involves the flow of gas and dust within molecular clouds into protostars and young stellar objects (YSOs) due to gravity. Along the way, these flows are shaped sign…
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…
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…
The JCMT Gould Belt Survey: A First Look at Southern Orion A with SCUBA-2
Steve Mairs, D. Johnstone, H. Kirk +52
We present the JCMT Gould Belt Survey's first look results of the southern extent of the Orion A Molecular Cloud (). Employing a two-step struct…
