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…

The GUAPOS project -- VII: Physical structure and molecular environment of the G31.41+0.31 HII region

R. Cesaroni, M. T. Beltrán, V. M. Rivilla +6

Ionised regions around OB-type stars are formed at an early stage of their evolution and are important to investigate the formation process of these objects. However, so far only f…

Diverse stages of star formation in the IRAS 18162-2048 region. Emergence of UV Feedback

R. Fedriani, G. Anglada, A. Caratti o Garatti +15

Methods: We obtained adaptive optics-assisted integral field spectroscopy in the near-infrared (IR) band () with VLT/SINFONI, complemented by VLA X and…

A multi-scale view of the magnetic field morphology in the hot molecular core G31.41+0.31

C. Y. Law, M. T. Beltrán, R. S. Furuya +9

Multiscale studies of the morphology and strength of the magnetic field are crucial to properly unveil its role and relative importance in high-mass star and cluster formation. G31…

ALMAGAL I. The ALMA evolutionary study of high-mass protocluster formation in the Galaxy. Presentation of the survey and early results

S. Molinari, P. Schilke, C. Battersby +73

Fundamental questions about the physics responsible for fragmenting molecular parsec-scale clumps into cores of ~1000 au are still open, that only a statistically significant inves…

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…
