cds-question@unistra.fratomic-physicsAs the most abundant element in the universe after hydrogen and helium, oxygen plays a key role in planetary, stellar, and galactic astrophysics. Its abundance is especially influential on stellar structure and evolution, and as the dominant opacity contributor at the base of the Sun's convection zone it is central to the discussion around the solar modelling problem. However, abundance analyses require complete and reliable sets of atomic data. We present extensive atomic data for OI, by using the multi-configuration Dirac-Hartree-Fock and relativistic configuration interaction methods. Lifetimes and transition probabilities for radiative electric dipole transitions are given and compared with results from previous calculations and available measurements. The accuracy of the computed transition rates is evaluated by the differences between the transition rates in Babushkin and Coulomb gauges, as well as by the cancellation factors. 402 out of 989 computed transitions in this work are assigned to the accuracy classes AA-B, i.e. with uncertainties less than 10%, according to the National Institute of Standards and Technology Atomic Spectra Database. We discuss the influence of the new log(gf) values on the solar oxygen abundance and ultimately advocate log{epsilon}_O_=8.70+/-0.04.2023A&A...674A..54Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/674/A54CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/674/A54https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/674/A54http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/674/A54https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/674/A54https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/674/A54http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/674/A54GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/674/A54/tablea1Energy levels and lifetimes for OIrecnoRecord number assigned by the VizieR team.
