Isomer-specific excitation of formic acid in collisions with helium atoms
Karina Sogomonyan, Anzhela Veselinova-Marinova, François Lique +1
An accurate estimation of the molecular abundances of isomers in the interstellar medium (ISM) is necessary to unravel the underlying chemistry and physics. After the recent detect…
Quantum and Structural Effects Captured via a Statistical Method: the SACM Applied to HCN and HNC Colliding with CO
F. Tonolo, E. Quintas-Sánchez, A. Batista-Planas +2
This work spotlights the Statistical Adiabatic Channel Model as an efficient and accurate method for deriving low temperature (de)-excitation rate coefficients for collisions induc…
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…
Stellar age determination using deep neural networks: Isochrone ages for 1.3 million stars, based on BaSTI, MIST, PARSEC, Dartmouth and SYCLIST evolutionary grids
T. Boin, L. Casamiquela, M. Haywood +4
We aim to develop a model-driven deep learning approach to age determination, by training neural networks on stellar evolutionary grids. Contrary to the usual data-driven deep lear…
Carbon chain diversity in L1544 and IRAS 16293-2422: an astrochemical pathfinder study for the SKAO
Lisa Giani, Eleonora Bianchi, Anthony Remijan +12
Astrochemical observations have revealed a surprisingly high level of chemical complexity, including long carbon chains, in the earliest stages of Sun-like star formation. The orig…
