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…
Betelgeuse fainter in the sub-millimetre too: an analysis of JCMT and APEX monitoring during the recent optical minimum
Thavisha E. Dharmawardena, Steve Mairs, Peter Scicluna +5
Betelgeuse is the nearest Red Supergiant star and it underwent an unusually deep minimum at optical wavelengths during its most recent pulsation cycle. We present submillimetre obs…
The JCMT Transient Survey: An Extraordinary Submillimetre Flare in the T Tauri Binary System JW 566
Steve Mairs, Bhavana Lalchand, Geoffrey C. Bower +7
The binary T Tauri system JW 566 in the Orion Molecular Cloud underwent an energetic, short-lived flare observed at submillimetre wavelengths by the SCUBA-2 instrument on 26 Novemb…
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…
