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…
Numerical methods comparison for protostellar collapse calculations
B. Commercon, P. Hennebelle, E. Audit +2
The development of parallel supercomputers allows today the detailed study of the collapse and the fragmentation of prestellar cores with increasingly accurate numerical simulation…
Gas-phase Elemental abundances in Molecular cloudS (GEMS) III. Unlocking the CS chemistry: the CS+O reaction
N. Bulut, O. Roncero, A. Aguado +36
CS is among the most abundant gas-phase S-bearing molecules in cold dark molecular clouds. It is easily observable with several transitions in the millimeter wavelength range, and…
The first Galaxy scale hunt for the youngest high-mass protostars
T. Csengeri, S. Bontemps, F. Wyrowski +17
The origin of massive stars is a fundamental open issue in modern astrophysics. Pre-ALMA interferometric studies reveal precursors to early B to late O type stars with collapsing e…
Chemical and physical characterization of collapsing low-mass prestellar dense cores
U. Hincelin, B. Commercon, V. Wakelam +3
The first hydrostatic core, also called the first Larson core, is one of the first steps in low-mass star formation, as predicted by theory. With recent and future high performance…
The dynamically young outflow of the Class 0 protostar Cha-MMS1
L. A. Busch, A. Belloche, S. Cabrit +2
On the basis of its low luminosity, its chemical composition, and the absence of a large-scale outflow, the dense core Cha-MMS1 located in the Chamaeleon I molecular cloud was prop…
