Hot water emission during an outburst in a classical T Tauri star

Zhen Guo, Javier Osses, Vitor Fermiano +34

In this paper, we present observations of an eruptive young star in the Rosette Nebula, identified by the Gaia Science Alerts system using Gaia time series data. We aim to investig…

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…

Gaia24ccy: An outburst followed the footsteps of its predecessor

Koshvendra Singh, Joe P. Ninan, Zhen Guo +25

Accretion-driven outbursts in young stellar objects remain poorly understood, largely limited by a statistically small sample of closely followed-up events. This underscores the im…

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…

Eruptive YSOs in Cygnus-X: a mid-infrared variability study with NEOWISE and SPICY

C. Morris, Z. Guo, P. W. Lucas +3

The mass accretion process controls pre-main-sequence evolution, although its intrinsic instability has yet to be fully understood, especially towards the protostellar stage. In th…
