Rotation Velocities of DA White Dwarfs with Convective Atmospheres
Karl, C.; Heber, U.; Napiwotzki, R.; Dreizler, S.; Koester, D.; Reid, I.N. (Astronomical Society of the Pacific, 2005)The sharp H® NLTE line cores of hydrogen rich (DA) white dwarfs allow their projected rotational velocities to be determined. High resolution optical spectra of 22 stars obtained with the Keck I telescope are matched by ... -

Spectral analysis of the binary sdB star Feige 36
Edelmann, H.; Heber, U.; Napiwotzki, R.; Reid, I.N.; Saffer, R. (Astronomical Society of the Pacific, 1999)The sdB stars Feige 36 is a short-period, single-lined spectroscopic binary. Aymospheric parameters and abundances are determined from high-resolution Keck spectra. Feige 36 lies near the zero-age extreme Horizontal Branch ...
