Date & Time: 2025/February/20 17:00-18:00, Venue: Zoom TV Conference System. This is an informal seminar on the formation of stars and planets. We welcome anyone interested in the subject.
Abstract:
The formation of high-mass stars remains an open question due to the difficulty of observing their distant, embedded birth environments. We conducted the ALMA Survey of 70 µm Dark High-mass Clumps in Early Stages (ASHES) to constrain the initial conditions. We identified 839 embedded cores, the largest sample of cores in the very early stage of high-mass star formation. This talk will present the core properties revealed by ASHES, including core mass, spatial distribution, fragmentation, and infall motion. Our results support the clump-fed scenario in which initially low-mass cores grow by gas-feeding from the surrounding environment to form high-mass stars.
