      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 accretion -- prolonged periods of very low accretion ...

    • The JCMT Transient Survey : Single Epoch Transients and Variability of Faint Sources 

      Johnstone, Doug; Lalchand, Bhavana; Mairs, Steve; Shang, Hsien; Chen, Wen Ping; Bower, Geoffrey C.; Herczeg, Gregory J.; Lee, Jeong-Eun; Forbrich, Jan; Chen, Bo-Yan; Contreras-Pena, Carlos; Lee, Yong-Hee; Park, Wooseok; Broughton, Colton; Plovie, Spencer; Team, The JCMT Transient (2022-09-15)
      Short-duration flares at millimeter wavelengths provide unique insights into the strongest magnetic reconnection events in stellar coronae, and combine with longer-term variability to introduce complications to next-generation ...

    • The JCMT Transient Survey: An Extraordinary Submillimeter Flare in the T Tauri Binary System JW 566 

      Mairs, Steve; Lalchand, Bhavana; Bower, Geoffrey C.; Forbrich, Jan; Bell, Graham S.; Herczeg, Gregory J.; Johnstone, Doug; Chen, Wen-Ping; Lee, Jeong-Eun; Hacar, Alvaro (2019-01-23)
      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 November 2016 (UT). The emission faded by nearly ...

    • Twenty-five Years of Accretion onto the Classical T Tauri Star TW Hya 

      Herczeg, Gregory J.; Chen, Yuguang; Donati, Jean-Francois; Dupree, Andrea K.; Walter, Frederick M.; Hillenbrand, Lynne A.; Johns-Krull, Christopher M.; Manara, Carlo F.; Günther, Hans Moritz; Fang, Min; Schneider, P.

      Accretion plays a central role in the physics that governs the evolution and dispersal of protoplanetary disks. The primary goal of this paper is to analyze the stability over time of the mass accretion rate onto TW Hya, ...
