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 CepA disk-outflow system at <=0.2'' or <=100au resolution
H. Beuther, C. Gieser, V. Aberham +21
Context: Although there has been significant progress, the physical properties and potential fragmentation of accretion disks around high-mass protostars remain poorly constrained.…
From Fragments to Flares: Migration, Tidal Disruption, and Observable Bursts in Massive Protostellar Disks
Vardan Elbakyan, Rolf Kuiper, André Oliva +4
We investigate how resolving the inner few astronomical units of a massive protostellar disk affects the migration, disruption, and accretion signatures of an inward-moving fragmen…
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…
The role of detailed gas and dust opacities in shaping the evolution of the inner disc edge subject to episodic accretion
Michael Cecil, Mario Flock, Mykola G. Malygin +4
We investigate the effects of different dust and gas opacity descriptions on the structure and evolution of the inner regions of protoplanetary discs. The influence on the episodic…
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…
