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…
Virial-based extraction of structures in numerical simulations: The vibes tool
Simon Chevalier, Fabien Louvet, Yann Bernard +9
The processes that determine the stellar initial mass function (IMF) and its connection to the core mass function (CMF) are among the major open questions in star formation. The de…
S2D2: Small-scale Significant substructure DBSCAN Detection II. Tracing episodes and gradients of star formation activity
Marta González, Isabelle Joncour, Estelle Moraux +5
We provide the community with a homogeneous catalogue of small, significant substructures (henceforth NESTs) extracted from the spatial distribution of Young Stellar Objects (YSOs)…
On the coupled origin of the stellar IMF and multiplicity
B. Thomasson, I. Joncour, E. Moraux +3
In the solar neighborhood, the Initial Mass Function (IMF) follows is canonically described by the Salpeter power-law slope for the high-mass range. The stellar IMF may directly re…
DAWN. I. Simulating the formation and early evolution of stellar clusters with Phantom N-Body
Yann Bernard, Estelle Moraux, Daniel J. Price +3
Context. Simulating stellar dynamics in a molecular cloud environment is numerically challenging due to the strong coupling between young stars and their surrounding gas, and the l…
