Evidence for a bloated massive protostar in IRAS20126+4104
Riccardo Cesaroni
Variability is a well known phenomenon in low-mass young stellar objects, but in recent years the monitoring of methanol masers and infrared continuum emission has permitted the de…
Protostellar Outflows at the EarliesT Stages (POETS) VI. Evidence of disk-wind in G11.92-0.61 MM1
O. S. Bayandina, L. Moscadelli, R. Cesaroni +3
Magnetohydrodynamic disk-winds play a key role in the formation of massive stars by providing the fine-tuning between accretion and ejection, where excess angular momentum is redir…
Dissecting the disk and the jet of a massive (proto)star. An ALMA view of IRAS20126+4104
R. Cesaroni, D. Galli, M. Padovani +2
We investigate one of the best examples of disk+jet systems around an early B-type (proto)star, IRAS20126+4104. This object is an ideal target for resolution of its disk and the de…
Radio outburst from a massive (proto)star. III. Unveiling the bipolarity of the radio jet from S255IR NIRS3
R. Cesaroni, L. Moscadelli, A. Caratti o Garatti +6
We report new Very Large Array high-resolution observations of the radio jet from the outbursting high-mass star S255IR~NIRS3. The images at 6, 10, and 22.2 GHz confirm the existen…
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…
Discovery of a sub-Keplerian disk with jet around a 20Msun young star. ALMA observations of G023.01-00.41
A. Sanna, A. Koelligan, L. Moscadelli +9
It is well established that Solar-mass stars gain mass via disk accretion, until the mass reservoir of the disk is exhausted and dispersed, or condenses into planetesimals. Accreti…
Radio outburst from a massive (proto)star. When accretion turns into ejection
R. Cesaroni, L. Moscadelli, R. Neri +6
Context. Recent observations of the massive young stellar object S255 NIRS 3 have revealed a large increase in both methanol maser flux density and IR emission, which have been int…
A study on subarcsecond scales of the ammonia and continuum emission toward the G16.59-0.05 high-mass star-forming region
L. Moscadelli, R. Cesaroni, Á. Sánchez-Monge +4
We wish to investigate the structure, velocity field, and stellar content of the G16.59-0.05 high-mass star-forming region, where previous studies have established the presence of…
Methanol and water masers in IRAS 20126+4104: The distance, the disk, and the jet
L. Moscadelli, R. Cesaroni, M. J. Rioja +2
IRAS 20126+4104 is one of the best candidates for a high-mass (proto)star surrounded by an accretion disk. Such a fact may be used to set constraints on theories of high-mass star…
