Chemistry and ro-vibrational excitation of CH in the planetary nebula NGC 7027
Milan Sil, Alexandre Faure, Helmut Wiesemeyer +5
Small carbon hydride cations, such as the methylidyne ion (CH), play an important role in the chemistry of the interstellar medium (ISM). They participate in gas-phase reaction…
A differentiable and optimizable 3D model for interpretation of observed spectral data cubes
T. Grassi, J. E. Pineda, S. Spezzano +6
Molecular spectral cubes of prestellar cores encode the information on the physical and chemical properties of these objects along the line of sight. To retrieve this information,…
Analysis of the isotopologues of CS, CCS, CCCS, HCS+, HCCS+, and H2CS in TMC-1 with the QUIJOTE line survey
R. Fuentetaja, C. Cabezas, Y. Endo +7
We performed a detailed analysis of the isotopologues with 13C, 34S, 33S, and 36S of the sulphur-bearing molecules CS, CCS, CCCS,HCS+, HCCS+, and H2CS towards TMC-1 using the QUIJO…
Hunting pre-stellar cores with APEX: overview
P. Caselli, S. Spezzano, E. Redaelli +8
[Abridged] Pre-stellar cores are centrally concentrated starless cores on the verge of star formation and they represent the initial conditions for star and planet forma…
PDRs4All. XII. FUV-driven formation of hydrocarbon radicals and their relation with PAHs
J. R. Goicoechea, J. Pety, S. Cuadrado +25
We present subarcsecond-resolution ALMA mosaics of the Orion Bar PDR in [CI] 609um, C2H (4-3), and C18O (3-2) emission lines complemented by JWST images of H2 and aromatic infrared…
An 18-25 GHz spectroscopic survey of dense cores in the Chamaeleon I molecular cloud
Dariusz C. Lis, William D. Langer, Jorge L. Pineda +9
We extend the survey for organics in the southern hemisphere by observing two cores in the Chamaeleon complex using NASA's Deep Space Network 70-m antenna in Canberra, Australia, o…
Chemistry and ro-vibrational excitation of HeH in the Planetary Nebula NGC 7027
Milan Sil, Alexandre Faure, Helmut Wiesemeyer +5
HeH belongs to the class of "reactive" ions that can be destroyed so quickly that chemical formation and destruction rates may compete with inelastic rates and should be consid…
Hunting pre-stellar cores with APEX: IRAS16293E (Oph464)
S. Spezzano, E. Redaelli, P. Caselli +7
Pre-stellar cores are the first steps in the process of star and planet formation. However, the dynamical and chemical evolution of pre-stellar cores is still not well understood.…
Fate and detectability of rare gas hydride ions in nova ejecta: A case study with nova templates
Milan Sil, Ankan Das, Ramkrishna Das +6
HeH was the first heteronuclear molecule to form in the metal-free Universe after the Big Bang. The molecule gained significant attention following its first circumstellar dete…
Similar levels of deuteration in the pre-stellar core L1544 and the protostellar core HH211
K. Giers, S. Spezzano, P. Caselli +6
In the centre of pre-stellar cores, deuterium fractionation is enhanced due to the low temperatures and high densities. Therefore, the chemistry of deuterated molecules can be used…
An accurate set of HO H collisional rate coefficients for non-LTE modelling of warm interstellar clouds
Sándor Demes, François Lique, Alexandre Faure +1
Hydronium (HO) was first detected in 1986 in interstellar molecular clouds. It was reported in many galactic diffuse and dense regions, as well as in extragalactic sources.…
