The Zero-Age Massive Stellar Population of W49A from VLA Observations
M. Juárez-Gama, R. Galván-Madrid, G. Suárez +14
We use all-configuration VLA data at 3.3 cm with a physical resolution of ~2000 AU to infer the embedded zero-age massive stellar population of the W49A protocluster, as traced by…
ALMA-IMF XXII. Role of core subfragmentation in the IMF origin: Hierarchical fragmentation cascade and CMF in W43-MM1
F. Motte, N. Le Nestour, R. Veyry +29
We aim to predict how the currently observed top-heavy CMF in the massive protocluster W43-MM1 evolves due to core subfragmentation. We used getsf to extract sources in 5 ALMA imag…
Challenges in probing turbulent and magnetic support in cores: the W43-MM1 protocluster case study
M. Valeille-Manet, F. Louvet, F. Motte +13
Estimating the level of non-thermal support in cores is both challenging and crucial for constraining the earliest stages of star formation. We quantify the kinetic and magnetic su…
HOTDISK. Finding Massive Protostellar Disks with Water and Refractory Molecular Species
Kai Yang, Yichen Zhang, Kei E. I. Tanaka +16
We present high-angular-resolution (, au) ALMA Band~6 observations from the HOTDISK project (Hot-Origin Tracer survey of DISKs of massive pro…
ALMA-IMF. XXI.: NH kinematics in the G012.80 protocluster: Evidence for filament rotation and evolution
J. Salinas, A. M. Stutz, R. H. Ãlvarez-Gutiérrez +20
(abridged) We aim to characterize kinematic processes in the G012.80 protocluster. We principally focus on the NH(10) emission to trace the dense and cold gas. Additiona…
Estimation of the magnetic field strength from ALMA dust polarization in the protocluster G327.29
A. Koley, P. Sanhueza, A. M. Stutz +5
Magnetic fields and turbulence may play a crucial role in the evolution of molecular clouds and ultimately in the formation of dense cores and stars. Despite being studied in many…
