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 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…
Young Stellar Objects in the Carina nebula: Near-Infrared variability and spectroscopy
Jura Borissova, Radostin Kurtev, Josemanuel Escobar +10
We present a catalog of 652 young stellar objects (YSOs) in the Carina star-forming region. The catalog was constructed by combining near-infrared Ks-band variability from the VIST…
The verification of periodicity with the use of recurrent neural networks
Niall Miller, Philip Lucas, Yi Sun +3
The ability to automatically and robustly self-verify periodicity present in time-series astronomical data is becoming more important as data sets rapidly increase in size. The age…
