PRODIGE -- Envelope to Disk with NOEMA II. Small-scale temperature structure and a streamer feeding the SVS13A protobinary using CH3CN and DCN
T. -H. Hsieh, D. M. Segura-Cox, J. E. Pineda +18
Aims. We present high sensitivity and high-spectral resolution NOEMA observations of the Class 0/I binary system SVS13A, composed of the low-mass protostars VLA4A and VLA4B with a…
Stratified Distribution of Organic Molecules at the Planet-Formation Scale in the HH 212 Disk Atmosphere
Chin-Fei Lee, Claudio Codella, Cecilia Ceccarelli +1
Formamide (NH2CHO) is considered an important prebiotic molecule because of its potential to form peptide bonds. It was recently detected in the atmosphere of the HH 212 protostell…
Tracking the ice mantle history in the Solar-type Protostars of NGC 1333 IRAS 4
Marta De Simone, Cecilia Ceccarelli, Claudio Codella +13
To understand the origin of the diversity observed in exoplanetary systems, it is crucial to characterize the early stages of their formation, represented by Solar-type protostars.…
Chemical Differentiation and Temperature Distribution on a Few au Scale around the Protostellar Source B335
Yuki Okoda, Yoko Oya, Muneaki Imai +5
Resolving physical and chemical structures in the vicinity of a protostar is of fundamental importance for elucidating their evolution to a planetary system. In this context, we ha…
Hot methanol in the [BHB2007] 11 protobinary system: hot corino versus shock origin? : FAUST V
C. Vastel, F. Alves, C. Ceccarelli +63
Methanol is a ubiquitous species commonly found in the molecular interstellar medium. It is also a crucial seed species for the building-up of the chemical complexity in star formi…
Chemical and Physical Characterization of the Isolated Protostellar Source CB68: FAUST. IV
Muneaki Imai, Yoko Oya, Brian Svoboda +1
Chemical diversity of low-mass protostellar sources has so far been recognized, and environmental effects are invoked as its origin. In this context, observations of isolated proto…
