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…

Hints of Disk Substructure in the First Brown Dwarf with a Dynamical Mass Constraint
Alejandro SantamarÃa Miranda, Pietro Curone, Laura Pérez +14
We present high-resolution ALMA observations at 0.89 mm of the Class II brown dwarf 2MASS J04442713+2512164 (2M0444), achieving a spatial resolution of 0046 (…

Observations of pre- and proto-brown dwarfs in nearby clouds: paving the way to further constraining theories of brown dwarf formation
Aina Palau, Nuria Huelamo, David Barrado +2
Brown Dwarfs (BDs) are crucial objects in our understanding of both star and planet formation. However, there is still an unconcluded debate about which is the dominant formation m…
