CORINOS I: JWST/MIRI Spectroscopy and Imaging of a Class 0 protostar IRAS 15398-3359
Yao-Lun Yang, Joel D. Green, Klaus M. Pontoppidan +13
The origin of complex organic molecules (COMs) in young Class 0 protostars has been one of the major questions in astrochemistry and star formation. While COMs are thought to form…
Ice Age : Chemo-dynamical modeling of Cha-MMS1 to predict new solid-phase species for detection with JWST
Mihwa Jin, Ka Ho Lam, Melissa K. McClure +6
Chemical models and experiments indicate that interstellar dust grains and their ice mantles play an important role in the production of complex organic molecules (COMs). To date,…
Millimeter wave spectrum and search for vinyl isocyanate toward Sgr B2(N) with ALMA
K. Vávra, L. Kolesniková, A. Belloche +9
The interstellar detections of isocyanic acid, methyl isocyanate, and very recently also ethyl isocyanate, open the question of the possible detection of vinyl isocyanate in the in…
Resolving desorption of complex organic molecules in a hot core: Transition from non-thermal to thermal desorption or two-step thermal desorption?
Laura A. Busch, Arnaud Belloche, Robin T. Garrod +2
Using the high angular resolution provided by the ALMA interferometre we want to resolve the COM emission in the hot molecular core Sagittarius B2(N1) and thereby shed light on the…
Interstellar detection and chemical modeling of iso-propanol and its normal isomer
A. Belloche, R. T. Garrod, O. Zingsheim +2
The detection of a branched alkyl molecule in the high-mass star forming protocluster Sgr B2(N) permitted by the advent of ALMA revealed a new dimension of interstellar chemistry.…
Toward the limits of complexity of interstellar chemistry: Rotational spectroscopy and astronomical search for n- and i-butanal
M. Sanz-Novo, A. Belloche, V. M. Rivilla +11
In recent times, large organic molecules of exceptional complexity have been found in diverse regions of the interstellar medium. In this context, we aim to provide accurate freque…
