Digging into the Interior of Hot Cores with ALMA (DIHCA). VI. The Formation of Low-mass Multiple Systems in High-mass Cluster-forming Regions
Qiuyi Luo, Patricio Sanhueza, Stella S. R. Offner +14
Most stars form in multiple systems, with profound implications in numerous astronomical phenomena intrinsically linked to multiplicity. However, our knowledge about the process on…
ALMA-IMF XX: Core fragmentation in the W51 high-mass star-forming region
T. Yoo, A. Ginsburg, J. Braine +27
We present a study of core fragmentation in the W51-E and W51-IRS2 protoclusters in the W51 high-mass star-forming region. The identification of core fragmentation is achieved by t…
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…
ALMA-IMF XII: Point-process mapping of 15 massive protoclusters
P. Dell'Ova, F. Motte, A. Gusdorf +29
A crucial aspect in addressing the challenge of measuring the core mass function, that is pivotal for comprehending the origin of the initial mass function, lies in constraining th…
Digging into the Interior of Hot Cores with ALMA (DIHCA). IV. Fragmentation in High-mass Star-Forming Clumps
Kosuke Ishihara, Patricio Sanhueza, Fumitaka Nakamura +10
Fragmentation contributes to the formation and evolution of stars. Observationally, high-mass stars are known to form multiple-star systems, preferentially in cluster environments.…
