Early Stages of High-mass Star Formation
Investigating the Origin of Stellar Masses (Official website)
ALMA-IMF is the first ALMA Large Program in high-mass star formation (PIs: Frederique Motte, Adam Gingsburg, Patricio Sanhueza, and Fabien Louvet). ALMA Large Programs are meant to address key scientific questions in the field. With ALMA-IMF, we aim to understand the origin of the initial mass function (IMF) by studing its precursor, the core mass function (CMF). Before ALMA-IMF, the majority of sistematic and statisiticly significant CMF studies focused in nearby, low-mass star-forming regions. Albeit such studies contribute to understand star formation in such regions, most stars in the Galaxy form in massive cluster along with high-mass stars. Regions forming high- and low-mass stars are the targets of ALMA-IMF. Beyond the CMF studies, ALMA-IMF observations allows the production of diverse science, including, e.g., outflows, chemistry, and filaments. People interested in this project can check the paper below of visit the official ALMA-IMF website for further details and data retrival.
