An improved solar abundance of osmium based on new lifetime measurements in OS I
Abstract
A new solar abundance of osmium, AOs = 1.45±0.10, in agreement with meteorites, is derived from 9 lines of Os I observed in the photospheric spectrum. This result is based on new lifetime measurements for 6 levels of Os I performed by time-resolved observation of the reemitted fluorescence after pulsed laser excitation.
