Abundance of HOCO+ and CO2 in the outer layers of the L1544 prestellar core
Charlotte Vastel, Cecilia Ceccarelli, Bertrand Lefloch +1
The L1544 prestellar core has been observed as part of the ASAI IRAM Large Program at 3 mm. These observations led to the detection of many complex molecules. In this Letter, we re…
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…
The (impossible?) formation of acetaldehyde on the grain surfaces: insights from quantum chemical calculations
Joan Enrique-Romero, Albert Rimola, Cecilia Ceccarelli +1
Complex Organic Molecules (COMs) have been detected in the interstellar medium (ISM). However, it is not clear whether their synthesis occurs on the icy surfaces of interstellar gr…
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…
