The long-term outburst(s) of GPSV16: from an intermediate to a FUor classification
Carlos Contreras Peña, Jeong-Eun Lee, Philip W. Lucas +8
FU Ori outbursts are thought to play a key role in stellar mass assembly and in the chemistry of protoplanetary disks during the early formation of stars. However, uncertainties re…
The circumstellar environment of the young, low-mass dipper star JH 223. Accretion and large-scale magnetic field topology
T. P. Freitas, J. Bouvier, B. Zaire +11
Studies of magnetospheric accretion and magnetic field topology in T Tauri stars have advanced over the years, but their applications to fully convective, very-low-mass T Tauri sta…
The Outbursting YSOs Catalogue (OYCAT)
C. Contreras Peña, J. -E. Lee, G. Herczeg +39
YSOs can display unpredictable and high-amplitude rises in brightness that can last from a few months to possibly over 100 years. These types of outbursts are explained by large ch…
VVV-WIT-13: an eruptive young star with cool molecular features
Zhen Guo, Philip Lucas, Sergey N. Yurchenko +27
Here we investigate an infrared eruptive source, identified from the decade-long VISTA Variables in the Via Lactea survey (VVV). We named this target after a group of variable sour…
"Oh FUors where art thou": A search for long-lasting YSO outbursts hiding in infrared surveys
Carlos Contreras Peña, Jeong-Eun Lee, Ho-Gyu Lee +11
Long-lasting episodes of high accretion can strongly impact stellar and planetary formation. However, the universality of these events during the formation of young stellar objects…
Sub-Millimeter Variability in the Envelope & Warped Protostellar Disk of the Class 0 Protostar HOPS 358
Patrick D. Sheehan, Doug Johnstone, Carlos Contreras Peña +7
The JCMT Transient Survey recently discovered that the Class 0 protostar HOPS 358 decreased in 350 GHz continuum brightness by % over the course of four years before bright…
