First ALMA maps of HCO, an important precursor of complex organic molecules, towards IRAS 16293-2422
V. M. Rivilla, M. T. Beltrán, A. Vasyunin +4
The formyl radical HCO has been proposed as the basic precursor of many complex organic molecules such as methanol (CHOH) or glycolaldehyde (CHOHCHO). Using ALMA, we have m…
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…
The SOMA Radio Survey. I. Comprehensive SEDs Of High-Mass Protostars From Infrared To Radio And The Emergence Of Ionization Feedback
V. Rosero, K. E. I. Tanaka, J. C. Tan +5
We study centimeter continuum emission of eight high- and intermediate-mass protostars that are part of the SOFIA Massive (SOMA) Star Formation Survey, thus building extended spect…
Detecting Infall in High-Mass Protostellar Objects
Maria T. Beltrán, Qizhou Zhang, Víctor M. Rivilla
The role of accretion disks in the formation of low-mass stars has been well assessed by means of high angular resolution observations at various wavelengths. These findings confir…
Complex Organic Molecules in Hot Molecular Cores/Corinos: Physics and Chemistry
Maria T. Beltrán, Víctor M. Rivilla
Hot molecular cores (HMCs), the cradles of massive stars, are the most chemically rich sources in the Galaxy. The typical masses of these cores (few hundreds of solar masses) make…
Nitrogen fractionation in high-mass star-forming cores across the Galaxy
L. Colzi, F. Fontani, V. M. Rivilla +4
The fractionation of nitrogen (N) in star-forming regions is a poorly understood process. To put more stringent observational constraints on the N-fractionation, we have observed w…
