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…
Quasi-Keplerian Be-Star Disks with Mimicking Viscosity
Michel Cure, Ignacio Araya, Rodrigo Meneses +5
Classical Be stars are fast-rotating B-type stars with gaseous quasi-Keplerian disks formed by equatorial ejection of material. While the viscous decretion disk (VDD) model reprodu…
Line-driven Radiative Winds in B-Supergiants: Bridging the Gap between Fast and Slow m-CAK Solutions
MatÃas Montesinos, Emil Zabala-Arroyo, Juan José Castro-Salgado +2
The modified Castor, Abbott, and Klein (m-CAK) theory predicts different wind regimes based on the line force parameter for changes in ionization () and the rotation parameter…
Observational Signatures of Planetary Tidal Disruption Events Around Solar-Mass Stars
MatÃas Montesinos, Sergei Nayakshin, Vardan Elbakyan +4
The tidal disruption of planets by their host stars represents a growing area of interest in transient astronomy, offering insights into the final stages of planetary system evolut…
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…
Volatile enrichment in low-mass planets: Signatures of past planetary disruption?
Mario Sucerquia, MatÃas Montesinos, Ana MarÃa Agudelo +1
Tidal disruption and engulfment events around main-sequence stars -- such as the luminous red nova ZTF SLRN-2020, a candidate planetary-engulfment event -- reveal the destruction o…
