Chemical abundances of the high-latitude Herbig Ae Star PDS2.

COWLEY C.R., HUBRIG S. and PRZYBILLA N.

Abstract (from CDS):

The Herbig Ae star PDS2 (CD -53° 251) is unusual in several ways. It has a high Galactic latitude, unrelated to any known star-forming region. It is at the cool end of the Herbig Ae sequence, where favourable circumstances facilitate the determination of stellar parameters and chemical abundances. We find Teff = 6500K and log(g) = 3.5. The relatively low vsin(i) = 12±2 km/s made it possible to use mostly weak lines for the abundances. PDS2 appears to belong to the class of Herbig Ae stars with normal volatile and depleted involatile elements, thus resembling the λ Boo stars. The intermediate volatile zinc consistently violates this pattern.
