Evidence for disks at an early stage in class 0 protostars?
M. Gerin, J. Pety, B. Commercon +8
The formation epoch of protostellar disks is debated because of the competing roles of rotation, turbulence, and magnetic fields in the early stages of low-mass star formation. Mag…
Chemical segregation in the young protostars Barnard 1b-N and S: evidence of pseudo-disk rotation in Barnard 1b-S
Asunción Fuente, Maryvonne Gerin, Jerome Pety +7
The extremely young Class 0 object B1b-S and the first hydrostatic core (FSHC) candidate, B1b-N, provide a unique opportunity to study the chemical changes produced in the elusive…
Thermal Jeans fragmentation within 1000 AU in OMC-1S
Aina Palau, Luis A. Zapata, Carlos G. Roman-Zuniga +6
We present subarcsecond 1.3 mm continuum ALMA observations towards the Orion Molecular Cloud 1 South (OMC-1S) region, down to a spatial resolution of 74 AU, which reveal a total of…
ALMA survey of massive cluster progenitors from ATLASGAL. Limited fragmentation at the early evolutionary stage of massive clumps
T. Csengeri, S. Bontemps, F. Wyrowski +18
The early evolution of massive cluster progenitors is poorly understood. We investigate the fragmentation properties from 0.3 pc to 0.06 pc scales of a homogenous sample of infrare…
The magnetic diffusivities in 3D radiative chemo-hydrodynamic simulations of protostellar collapse
Natalia Dzyurkevich, Benoit Commercon, Pierre Lesaffre +1
The grand question of star and planet formation is the distribution of magnetic flux in the protoplanetary disks. To answer it, a detailed self-consistent chemical evolution is nee…
