The precise determination of chemical abundances in stars is the key to a number of important disciplines in modern astrophysics including stellar evolution and nucleosynthesis as well as the chemical and dynamical evolution of the Galaxy. The basic transport mechanisms in stellar atmospheres rule the observational aspects of stellar surfaces which are

Vanadium abundances in early A stars
Publications of the Astronomical Society of the Pacific, 1978Vanadium-to-hydrogen ratios have been determined for Omicron Peg, HR 6127, HR 465 (rare-earth minimum), and HR 8216. With respect to the solar system, vanadium is overabundant in the first two stars, possibly normal in the third, and underabundant in the fourth.
