An update to the MARVEL dataset and ExoMol line list for 12C2
Laura K. McKemmish, Anna-Maree Syme, Jasmin Borsovszky +4
The spectrum of dicarbon (C2) is important in astrophysics and for spectroscopic studies of plasmas and flames. The C2 spectrum is characterized by many band systems with new ones…
The ExoMolOP Database: Cross-sections and k-tables for Molecules of Interest in High-Temperature Exoplanet Atmospheres
Katy L. Chubb, Marco Rocchetto, Sergei N. Yurchenko +7
A publicly available database of opacities for molecules of astrophysical interest, ExoMolOP, has been compiled for over 80 species, based on the latest line list data from the Exo…
Benchmark Calculations of Electron Impact Electronic Excitation of the Hydrogen Molecule
T. Meltzer, J. Tennyson, Z. Mašín +4
We present benchmark integrated and differential cross-sections for electron collisions with H using two different theoretical approaches, namely, the R-matrix and molecular co…
Analysis of the TiO isotopologues in stellar optical spectra
Ya. V. Pavlenko, Sergei N. Yurchenko, Laura K. McKemmish +1
This study is based on the use of the new ExoMol TiO rovibronic line lists to identify and model TiO isotopologue features in spectra of M-dwarfs. We aim to investigate problems in…
The 2020 release of the ExoMol database: molecular line lists for exoplanet and other hot atmospheres
Jonathan Tennyson, Sergei N. Yurchenko, Ahmed F. Al-Refaie +19
The ExoMol database (www.exomol.com) provides molecular data for spectroscopic studies of hot atmospheres. While the data is intended for studies of exoplanets and other astronomic…
ExoMol line lists -- XL. Ro-vibrational molecular line list for the hydronium ion (HO)
S. N. Yurchenko, Jonathan Tennyson, Steve Miller +3
A new line list for hydronium (HO) is computed. The line list is based on a new ab initio dipole moment surface (CCSD(T)/aug-cc-pVQZ) and a new empirical potential e…
