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…
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…
Insights gained from the Light Echo of Cepheus A HW2
Bringfried Stecklum, Verena Wolf
Cepheus A HW2 is a well-studied massive young stellar object (MYSO) featuring Class II methanol masers. Recently, certain maser components have been found to flare every five years…
Radiative transfer modeling of outbursts of massive young stellar objects
Verena Wolf
Young stellar objects (YSOs) accrete up to half of their material in short periods of enhanced mass accretion. For massive YSOs (MYSOs with more than 8 solar masses), accretion out…
The accretion burst of the massive young stellar object G323.46 -0.08
V. Wolf, B. Stecklum, A. Caratti o Garatti +10
Accretion bursts from low-mass young stellar objects (YSOs) are known for many decades. In recent years, the first accretion bursts of massive YSOs (MYSOs) have been observed. Thes…
