Organic chemistry in the first phases of Solar-type protostars
C. Ceccarelli, C. Codella, N. Balucani +7
Planetary systems such as our own are formed after a long process where matter condenses from diffuse clouds to stars, planets, asteroids, comets and residual dust, undergoing dram…
Mass ejection and time variability in protostellar outflows: Cep E. SOLIS XVI
A. de A. Schutzer, P. R. Rivera-Ortiz, B. Lefloch +46

We report a study of the low-mass Class-0 multiple system VLA 1623AB in the Ophiuchus star-forming region, using HCO (), CS (), and CCH () lines as…
Organic chemistry in the protosolar analogue HOPS-108: Environment matters
L. Chahine, A. López-Sepulcre, R. Neri +10
Hot corinos are compact regions around solar-mass protostellar objects that are very rich in interstellar complex organic molecules (iCOMs). They are believed to represent the very…
Seeds of Life in Space (SOLIS). XIII. Nitrogen fractionation towards the protocluster OMC-2 FIR4
Lucy Evans, Francesco Fontani, Charlotte Vastel +8
Isotopic fractionation is an important tool to investigate the chemical history of our Solar System (SS). In particular, the isotopic fraction of nitrogen (14N/15N) is lower in com…
The SVS13-A Class I chemical complexity as revealed by S-bearing species. SOLIS XIII
C. Codella, E. Bianchi, L. Podio +13
Aims: The goal is to obtain a census of S-bearing species using interferometric images, towards SVS13-A, a Class I object associated with a hot corino rich in interstellar complex…
Rotating Motion of the Outflow of IRAS 16293-2422 A1 at its Origin Point near the Protostar
Yoko Oya, Yoshimasa Watanabe, Ana López-Sepulcre +4
The Class 0 protostar IRAS 162932422 Source A is known to be a binary system (A1 and A2) or even a multiple system, which processes a complex outflow structure. We have observed…
FAUST II. Discovery of a Secondary Outflow in IRAS 15398-3359: Variability in Outflow Direction during the Earliest Stage of Star Formation?
Yuki Okoda, Yoko Oya, Logan Francis +66
We have observed the very low-mass Class 0 protostar IRAS 15398-3359 at scales ranging from 50 au to 1800 au, as part of the ALMA Large Program FAUST. We uncover a linear feature,…
