Complex morphology and kinematics at the heart of the very low luminosity object IRAM 04191+1522
N. Otten, I. de Gregorio-Monsalvo, N. Huélamo +3
The formation of the majority of brown dwarfs (BDs) remains uncertain. They may form in molecular cloud cores in a process akin to low mass star formation, or via fragmentation in…

Characterizing the physical and chemical properties of the Class I protostellar system Oph-IRS 44. Binarity, infalling streamers, and accretion shocks
E. Artur de la Villarmois, V. V. Guzmán, M. L. van Gelder +5
(Abridged) In the low-mass star formation process, theoretical models predict that material from the infalling envelope could be shocked as it encounters the outer regions of the d…

Sulfur oxides tracing streamers and shocks at low mass protostellar disk-envelope interfaces
X. -C. Liu, E. F. van Dishoeck, M. R. Hogerheijde +8
Accretion shocks are thought to play a crucial role in the early stages of star and planet formation, but their direct observational evidence remains elusive, particularly regardin…
