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 C…
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…
Self-similarity of the magnetic field at different scales: the case of G31.41+0.31
M. T. Beltrán, M. Padovani, D. Galli +11
Context. Dust polarization observations of the massive protocluster G31.41+0.31 carried out at ~1'' (~3750 au) resolution with the SMA at 870 microm have revealed one of the cleare…
The GUAPOS project. V: The chemical ingredients of a massive stellar protocluster in the making
Á. López-Gallifa, V. M. Rivilla, M. T. Beltrán +9
Most stars, including the Sun, are born in rich stellar clusters containing massive stars. Therefore, the study of the chemical reservoir of massive star-forming regions is crucial…
Radio outburst from a massive (proto)star. II. A portrait in space and time of the expanding radio jet from S255 NIRS3
R. Cesaroni, L. Moscadelli, A. Caratti o Garatti +6
Observations indicate that the accretion process in star formation may occur through accretion outbursts. This phenomenon has also now been detected in a few young massive (proto)s…
Fragmentation and kinematics in high-mass star formation: CORE-extension targeting two very young high-mass star-forming regions
H. Beuther, C. Gieser, S. Suri +24
Context: The formation of high-mass star-forming regions from their parental gas cloud and the subsequent fragmentation processes lie at the heart of star formation research. Aims:…
Core fragmentation and Toomre stability analysis of W3(H2O): A case study of the IRAM NOEMA large program CORE
A. Ahmadi, H. Beuther, J. C. Mottram +30
The fragmentation mode of high-mass molecular clumps and the properties of the central rotating structures surrounding the most luminous objects have yet to be comprehensively char…
The physical and chemical structure of Sagittarius B2. II. Continuum millimeter emission of SgrB2(M) and SgrB2(N) with ALMA
A. Sanchez-Monge, P. Schilke, A. Schmiedeke +8
The high-mass star forming sites SgrB2(M) and SgrB2(N) have been the target of numerous studies, revealing e.g. a rich chemistry. We want to characterize their physical and chemica…
Momentum-driven outflow emission from an O-type YSO: Comparing the radio jet with the molecular outflow
A. Sanna, L. Moscadelli, R. Cesaroni +3
Aims: We want to study the physical properties of the ionized jet emission in the vicinity of an O-type young stellar object (YSO), and estimate how efficient is the transfer of en…
