We investigate the presence of hub-filament systems in a large sample of 146 active proto-clusters, using HCO J=1-0 molecular line data obtained from the ATOMS survey.…
Revisit the rate of tidal disruption events: the role of the partial tidal disruption event
Shiyan Zhong, Shuo Li, Peter Berczik +1
Tidal disruption of stars in dense nuclear star clusters containing supermassive central black holes (SMBH) is modeled by high-accuracy direct N-body simulation. Stars getting too…
ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP): How do dense core properties affect the multiplicity of protostars?
Qiuyi Luo, Tie Liu, Kenichi Tatematsu +34
During the transition phase from a prestellar to a protostellar cloud core, one or several protostars can form within a single gas core. The detailed physical processes of this tra…
