  • We present the observational evidence of a pseudo-disc around the proto-brown dwarf Mayrit 1701117, the driving source of the large-scale HH 1165 jet. Our analysis is based on ALMA 12CO (2-1) line and 1.37 mm continuum observations at an angular resolution of ∼0.411. The pseudo-disc is a bright feature in the CO position-velocity diagram (PVD), elongated in a direction perpendicular to the jet axis, with a total (gas+dust) mass of ∼0.02 Mo, size of 165-192 AU, and a velocity spread of ±2 km s… CONTINUE READING
