Substructures in the Keplerian disc around the O-type (proto)star G17.64+0.16
L. T. Maud, R. Cesaroni, M. S. N. Kumar +20
We present the highest angular resolution (20x15mas - 44x33au) Atacama Large Millimeter/sub-millimeter Array (ALMA) observations currently possible of the proto-O-star G17.64+0.16…
Accelerating infall and rotational spin-up in the hot molecular core G31.41+0.31
M. T. Beltrán, R. Cesaroni, V. M. Rivilla +20
As part of our effort to search for circumstellar disks around high-mass stellar objects, we observed the well-known core G31.41+0.31 with ALMA at 1.4 mm with an angular resolution…
Chasing discs around O-type (proto)stars - ALMA evidence for an SiO disc and disc wind from G17.64+0.16
L. T. Maud, R. Cesaroni, M. S. N. Kumar +28
We present high angular resolution 0.2 arcsec continuum and molecular emission line Atacama Large Millimeter/sub-millimeter Array (ALMA) observations of G17.64+0.16 in Band 6 (220G…
Complex cyanides as chemical clocks in hot cores
V. Allen, F. F. S. van der Tak, C. Walsh
In the high-mass star-forming region G35.20-0.74N, small scale (about 800 AU) chemical segregation has been observed in which complex organic molecules containing the CN group are…
Chemical Segregation in Hot Cores With Disk Candidates: An investigation with ALMA
V. Allen, F. F. S. van der Tak, Ã. Sánchez-Monge +2
In the study of high-mass star formation, hot cores are empirically defined stages where chemically rich emission is detected toward a massive YSO. It is unknown whether the physic…
