Discovery of a Hot Corino in the Bok Globule B335
Muneaki Imai, Nami Sakai, Yoko Oya +11
We report the first evidence of a hot corino in a Bok globule. This is based on the ALMA observations in the 1.2 mm band toward the low-mass Class 0 protostar IRAS 19347+0727 in B3…
Infalling-Rotating Motion and Associated Chemical Change in the Envelope of IRAS 16293-2422 Source A Studied with ALMA
Yoko Oya, Nami Sakai, Ana López-Sepulcre +5
We have analyzed rotational spectral line emission of OCS, CH3OH, HCOOCH3, and H2CS observed toward the low-mass Class 0 protostellar source IRAS 16293-2422 Source A at a sub-arcse…
Geometric and Kinematic Structure of the Outflow/Envelope System of L1527 Revealed by Subarcsecond-resolution Observation of CS
Yoko Oya, Nami Sakai, Bertrand Lefloch +4
Subarcsecond-resolution images of the rotational line emissions of CS and c-CH obtained toward the low-mass protostar IRAS 043682557 in L1527 with the Atacama Large Mill…
Subarcsecond Analysis of Infalling-Rotating Envelope around the Class I Protostar IRAS 04365+2535
Nami Sakai, Yoko Oya, Ana López-Sepulcre +10
Sub-arcsecond images of the rotational line emission of CS and SO have been obtained toward the Class I protostar IRAS 043652535 in TMC-1A with ALMA. A compact component around…
