Clusters of Galaxies in X-rays
S. Schindler
X-ray observations of clusters at different redshifts are presented and compared. For the nearest cluster -- the Virgo cluster -- we show a comparison of the galaxy distribution an…
A constraint on the angular momentum evolution of Be stars
I. A. Steele
The Be star sample of Steele et al. (1998) has a distribution of v sin i's that is luminosity dependant, with giants having lower projected rotational velocities than dwarfs. We sh…
Morphology of the Virgo Cluster: Gas versus Galaxies
S. Schindler, B. Binggeli, H. Boehringer
We draw a quantitative comparison of the distribution of the galaxies and the intra-cluster gas in the Virgo cluster by extending the morphological analysis by Binggeli et al. (198…
On the possibility that rotation causes latitudinal abundance variations in stars
John M. Porter
The effect of rotation of a star on the distribution of chemical species in radiative zones is discussed. Gravity darkening generates a large radiative force on heavy element ions…
The 2dF QSO Redshift Survey
S. M. Croom, T. Shanks, B. J. Boyle +3
We present preliminary results from the 2-degree Field (2dF) QSO Redshift Survey currently under way at the Anglo-Australian Telescope. This survey aims to determine the redshifts…
Brown Dwarfs in the Pleiades Cluster. III. A deep IZ survey
M. R. Zapatero Osorio, R. Rebolo, E. L. Martin +5
We present the results of a deep CCD-based IZ photometric survey of a ~1 sq. deg area in the central region of the Pleiades Galactic open cluster. The magnitude coverage of our sur…
