Simulating Star Formation and Star Cluster Assembly in the Aquila Rift Using Archival Observations
Jeremy Karam, Michiko S. Fujii, Rachel Friesen +1
We simulate star formation and star cluster assembly inside a molecular cloud with parameters we derive directly from observations of the Aquila Rift. We model the evolution of sta…
Peculiar Dust Emission within the Orion Molecular Cloud
Parisa Nozari, Sarah Sadavoy, Edwige Chapillon +8
It is widely assumed that dust opacities in molecular clouds follow a power-law profile with an index, . Recent studies of the Orion Molecular Cloud (OMC) 2/3 complex, however,…
Filament Accretion and Fragmentation in the Perseus Molecular Cloud
Michael Chun-Yuan Chen, James Di Francesco, Rachel K. Friesen +6
Observations suggest that filaments in molecular clouds can grow by mass accretion while forming cores via fragmentation. Here we present one of the first large sample studies of f…
Filamentary mass accretion towards the high-mass protobinary system G11.92-0.61 MM2
S. Zhang, C. J. Cyganowski, J. D. Henshaw +5
We present deep, sub-arcsecond (2000 AU) resolution ALMA 0.82 mm observations of the former high-mass prestellar core candidate G11.92-0.61 MM2, recently shown to be an $\sim…
On the magnetic field properties of protostellar envelopes in Orion
Bo Huang, Josep M. Girart, Ian W. Stephens +23
We present 870 um polarimetric observations toward 61 protostars in the Orion molecular clouds, with ~400 au (1") resolution using the Atacama Large Millimeter/submillimeter Array.…
The Reservoir of the Per-emb-2 Streamer
Kotomi Taniguchi, Jaime E Pineda, Paola Caselli +4
Streamers bring gas from outer regions to protostellar systems and could change the chemical composition around protostars and protoplanetary disks. We have carried out mapping obs…
