ALMA observations of Magnetic Fields in the Massive Star-forming Region IRAS 18360-0537
Shixian Mo, Keping Qiu, Qizhou Zhang +6
Assessing the significance of magnetic fields in high-mass star formation remains one of the most challenging topics in astrophysics. In this study, we present full polarization ob…
The dominance of turbulence over magnetism in the formation of massive star cluster seeds
Junhao Liu, Patricio Sanhueza, Piyali Saha +32
High-mass stars form in protoclusters, where gravo-magnetic processes shape collapsing clouds and clumps to be elongated preferentially perpendicular to magnetic (B) fields. Yet it…
Digging into the Interior of Hot Cores with ALMA (DIHCA). VII. Disk candidates around high-mass stars and evidence of anisotropic infall
Fernando A. Olguin, Patricio Sanhueza, Yoko Oya +19
We study the kinematics of condensations in 30 fields forming high-mass stars with ALMA at a high-resolution of ~0.08'' on average (~230 au). The presence of disks is important for…
HOPS-288: A Laboratory for Complex Organics in Proto-multiple Systems
Shih-Ying Hsu, Nadia M. Murillo, Chin-Fei Lee +21
Complex organic molecules (COMs) in young stellar objects (YSOs) have attracted significant attention in recent years due to their potential connection to pre-biotic chemistry and…
ALMASOP: Inner-Envelope Structures of Protostars Driving Nascent Jets
Somnath Dutta, Chin-Fei Lee, Naomi Hirano +15
Protostellar jets provide valuable insight into the evolutionary stage and formation history of star-forming cores in their earliest phases. We investigated the inner envelope stru…
Detection of a septuple stellar system in formation via disk fragmentation
Shanghuo Li, Henrik Beuther, André Oliva +15
Stellar multiple systems play a pivotal role in cluster dynamics and stellar evolution, leading to intense astronomical phenomena like X-ray binaries, gamma-ray bursts, Type Ia sup…
