Line formation in solar granulation VII. CO lines and the solar C and O isotopic abundances

Scott, Patrick; Asplund, Martin; Grevesse, N; Sauval, A J

Description

CO spectral line formation in the Sun has long been a source of consternation for solar physicists, as have the elemental abundances it seems to imply. We modelled solar CO line formation using a realistic, ab initio, time-dependent 3D radiative-hydrodynamic model atmosphere. Results were compared with space-based observations from the ATMOS space shuttle experiment. We employed weak12C16O,13C16O and12C18O lines from the fundamental (Δv = 1) and first overtone (Au = 2) bands to determine the...[Show more]
