The circumstellar environment around the embedded protostar EC 53
Seokho Lee, Jeong-Eun Lee, Yuri Aikawa +2
EC53 is an embedded protostar with quasi-periodic emission in the near-IR and sub-mm. We use ALMA high-resolution observations of continuum and molecular line emission to describe…
Protostellar Evolution in Serpens Main: Possible Origin of Disk-Size Diversity
Yusuke Aso, Naomi Hirano, Yuri Aikawa +6
We have observed the submillimeter continuum condensations SMM2, SMM4, SMM9, and SMM11 in the star forming cluster Serpens Main using the Atacama Large Millimeter/submillimeter Arr…
H ortho-para spin conversion on inhomogeneous grain surfaces
Kenji Furuya, Yuri Aikawa, Tetsuya Hama +1
We investigate the evolution of the ortho-to-para ratio of overall (gas + ice) H via the nuclear spin conversion on grain surfaces coated with water ice under physical conditio…
Sulfur-Bearing Species Tracing the Disk/Envelope System in the Class I Protostellar Source Elias 29
Yoko Oya, Ana López-Sepulcre, Nami Sakai +11
We have observed the Class I protostellar source Elias 29 with Atacama Large Millimeter/submillimeter Array (ALMA). We have detected CS, SO, SO, SO, and SiO line emissio…
Realizing the Unique Potential of ALMA to Probe the Gas Reservoir of Planet Formation
L. Ilsedore Cleeves, Ryan Loomis, Richard Teague +21
Understanding the origin of the astonishing diversity of exoplanets is a key question for the coming decades. ALMA has revolutionized our view of the dust emission from protoplanet…
SCOPE: SCUBA-2 Continuum Observations of Pre-protostellar Evolution - Survey Description and Compact Source Catalogue
D. J. Eden, Tie Liu, Kee-Tae Kim +157
We present the first release of the data and compact-source catalogue for the JCMT Large Program SCUBA-2 Continuum Observations of Pre-protostellar Evolution (SCOPE). SCOPE consist…
