HOTDISK. Finding Massive Protostellar Disks with Water and Refractory Molecular Species
Kai Yang, Yichen Zhang, Kei E. I. Tanaka +16
We present high-angular-resolution (, au) ALMA Band~6 observations from the HOTDISK project (Hot-Origin Tracer survey of DISKs of massive pro…
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). VI. The Formation of Low-mass Multiple Systems in High-mass Cluster-forming Regions
Qiuyi Luo, Patricio Sanhueza, Stella S. R. Offner +14
Most stars form in multiple systems, with profound implications in numerous astronomical phenomena intrinsically linked to multiplicity. However, our knowledge about the process on…
MAGellanic Outflow and chemistry Survey (MAGOS): Hot cores in the LMC
Takashi Shimonishi, Kei E. I. Tanaka, Yichen Zhang +3
The Large Magellanic Cloud (LMC) provides a key laboratory for exploring the diversity of star formation and interstellar chemistry under subsolar metallicity conditions. We presen…
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…
Deep Andromeda JCMT-SCUBA2 Observations. The Submillimeter Maps and Giant Molecular Clouds
Sihan Jiao, Jingwen Wu, Hauyu Baobab Liu +23
We have carried out unprecedentedly deep, nearly confusion-limited JCMT-SCUBA2 mapping observations on the nearest spiral galaxy, M31 (Andromeda). The 850 m image with a …
