ngVLA Synthetic Observations of Ionized Gas in Massive Protostars
Jesús M. Jáquez-Domínguez, Roberto Galván-Madrid, Alfonso Trejo-Cruz +11
Massive star formation involves significant ionization in the innermost regions near the central object, such as gravitationally trapped H II regions, jets, ionized disks, or winds…
Density distributions, magnetic field structures and fragmentation in high-mass star formation
H. Beuther, C. Gieser, J. D. Soler +19
Methods: Observing the large pc-scale Stokes I mm dust continuum emission with the IRAM 30m telescope and the intermediate-scale (<0.1pc) polarized submm dust emission with the Sub…
Kinematics and stability of high-mass protostellar disk candidates at sub-arcsecond resolution -- Insights from the IRAM NOEMA large program CORE
Aida Ahmadi, H. Beuther, F. Bosco +28
The fragmentation mode of high-mass molecular clumps and the accretion processes that form the most massive stars () are still not well understood. To this end,…
Clustered star formation at early evolutionary stages. Physical and chemical analysis of the young star-forming regions ISOSS J22478+6357 and ISOSS J23053+5953
C. Gieser, H. Beuther, D. Semenov +20
We aim to characterize the physical and chemical properties of fragmented cores during the earliest evolutionary stages in the very young star-forming regions ISOSS J22478+6357 and…
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:…
Multi-scale view of star formation in IRAS 21078+5211: From clump fragmentation to disk wind
L. Moscadelli, H. Beuther, A. Ahmadi +23
In the massive star-forming region IRAS 21078+5211, a highly fragmented cluster (0.1~pc in size) of molecular cores is observed, located at the density peak of an elongated (1~pc i…
Multi-wavelength modelling of the circumstellar environment of the massive proto-star AFGL 2591 VLA 3
F. A. Olguin, M. G. Hoare, K. G. Johnston +13
We have studied the dust density, temperature and velocity distributions of the archetypal massive young stellar object (MYSO) AFGL 2591. Given its high luminosity ($L=2 \times 10^…
Chemical complexity in high-mass star formation: An observational and modeling case study of the AFGL 2591 VLA 3 hot core
C. Gieser, D. Semenov, H. Beuther +30
We present a detailed observational and modeling study of the hot core VLA 3 in the high-mass star-forming region AFGL 2591, which is a target region of the NOrthern Extended Milli…

F. Bosco, H. Beuther, A. Ahmadi +23
The formation process of high-mass stars (>8M) is poorly constrained, particularly, the effects of clump fragmentation creating multiple systems and the mechanism of mass a…

This study is part of the project ``CORE'', an IRAM/NOEMA large program consisting of observations of the millimeter continuum and molecular line emission towards 20 selected high-…
Young massive star cluster formation in the Galactic Centre is driven by global gravitational collapse of high-mass molecular clouds
A. T. Barnes, S. N. Longmore, A. Avison +19
Young massive clusters (YMCs) are the most compact, high-mass stellar systems still forming at the present day. The precursor clouds to such systems are, however, rare due to their…
Synthetic [CII] emission maps of a simulated molecular cloud in formation
A. Franeck, S. Walch, D. Seifried +10
The C ion is an important coolant of interstellar gas, and so the [CII] fine structure line is frequently observed in the interstellar medium. However, the physical and chemi…
