Hints of Disk Substructure in the First Brown Dwarf with a Dynamical Mass Constraint

We present high-resolution Atacama Large Millimeter/submillimeter Array (ALMA) observations at 0.89 mm of the Class II brown dwarf 2MASS J04442713+2512164 (2M0444), achieving a spatial resolution of 0 . 046 (similar to 6.4 au at the distance to the source
