26 Jul 2020 | Abstract: | 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 astronomical bodies, the dataset is widely
applicable. The basic form of the database is extensive line lists; these are
supplemented with partition functions, state lifetimes, cooling functions,
Land’e g-factors, temperature-dependent cross sections, opacities, pressure
broadening parameters, $k$-coefficients and dipoles. This paper presents the
latest release of the database which has been expanded to consider 80 molecules
and 190 isotopologues totaling over 700 billion transitions. While the
spectroscopic data is concentrated at infrared and visible wavelengths,
ultraviolet transitions are being increasingly considered in response to
requests from observers. The core of the database comes from the ExoMol project
which primarily uses theoretical methods, albeit usually fine-tuned to
reproduce laboratory spectra, to generate very extensive line lists for studies
of hot bodies. The data has recently been supplemented by line lists deriving
from direct laboratory observations, albeit usually with the use of ab initio
transition intensities. A major push in the new release is towards accurate
characterisation of transition frequencies for use in high resolution studies
of exoplanets and other bodies. | Source: | arXiv, 2007.13022 | Services: | Forum | Review | PDF | Favorites |
