Central stars of planetary nebulae in the Galactic bulge
P. J. N. Hultzsch, J. Puls, R. H. Mendez +4
Optical high-resolution spectra of five central stars of planetary nebulae (CSPN) in the Galactic Bulge have been obtained with Keck/HIRES in order to derive their parameters. Sinc…
Chemical abundances and winds of massive stars in M31: a B-type supergiant and a WC star in OB10
S. J. Smartt, P. A. Crowther, P. L. Dufton +5
We present high quality spectroscopic data for two massive stars in the OB10 association of M31, OB10-64 (B0Ia) and OB10-WR1 (WC6). Medium resolution spectra of both stars were obt…
Rotations and Abundances of Blue Horizontal-Branch Stars in Globular Cluster M15
Bradford B. Behr, Judith G. Cohen, James K. McCarthy
High-resolution optical spectra of eighteen blue horizontal-branch (BHB) stars in the globular cluster M15 indicate that their stellar rotation rates and photospheric compositions…
The Wind Momentum - Luminosity Relationship of Galactic A- and B- Supergiants
R. P. Kudritzki, J. Puls, D. J. Lennon +5
The Balmer lines of four A Ia - supergiants (spectral type A0 to A3) and fourteen B Ia and Ib - supergiants (spectral type B0 to B3) in the solar neighbourhood are analyzed by mean…
A New Spin on the Problem of HB Gaps: Stellar Rotation along the Blue Horizontal Branch of Globular Cluster M13
Bradford B. Behr, S. G. Djorgovski, Judith G. Cohen +4
We have determined the projected rotational velocities of thirteen blue horizontal-branch (BHB) stars in the globular cluster M13 via rotational broadening of metal absorption line…
Striking Photospheric Abundance Anomalies in Blue Horizontal-Branch Stars in Globular Cluster M13
Bradford B. Behr, Judith G. Cohen, James K. McCarthy +1
High-resolution optical spectra of thirteen blue horizontal-branch (BHB) stars in the globular cluster M13 show enormous deviations in element abundances from the expected cluster…
