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…
White paper on the relevance of the European Solar Telescope (EST) for the French heliophysics
E. Pariat, Q. Noraz, B. Perri +61
The project of the European Solar Telescope aims to provide a state-of-the art infrastructure to study the Sun and its interactions with Earth and the heliosphere. This 4.2m apertu…
ALMA-IMF XVII -- Census and lifetime of high-mass prestellar cores in 14 massive protoclusters
M. Valeille-Manet, S. Bontemps, T. Csengeri +24
High-mass prestellar cores are extremely rare. The search for such objects has long been hindered by small sample sizes, leading to large uncertainties in their lifetimes and the c…
ALMA-IMF XVI: Mass-averaged temperature of cores and protostellar luminosities in the ALMA-IMF protoclusters
F. Motte, Y. Pouteau, T. Nony +34
ALMA-IMF imaged 15 massive protoclusters down to a resolution of of 2 kau scales, identifying about 1000 star-forming cores. The mass and luminosity of these cores, which are funda…
