The forbidden abundance of oxygen in the Sun

Allende Prieto, Carlos; Lambert, David L; Asplund, Martin

Description

We reexamine closely the solar photospheric line at 6300 A° , which is attributed to a forbidden line of neutral oxygen and is widely used in analyses of other late-type stars. We use a three-dimensional time-dependent hydrodynamical model solar atmosphere that has been tested successfully against observed granulation patterns and an array of absorption lines. We show that the solar line is a blend with a Ni i line, as previously suggested but oftentimes neglected. Thanks to accurate atomic...[Show more]
