Elemental Abundances in the Broad Emission Line Region of Quasars at Redshifts larger than 4

M. Dietrich, I. Appenzeller, F. Hamann +4

We present observations of 11 high redshift quasars ($3.9 \la z \la 5.0$) observed with low spectral resolution in the restframe ultraviolet using FORS 1 at the VLT UT 1. The emiss…

RXJ0806.3+1527: a double degenerate binary with the shortest known orbital period (321s)

G. L. Israel, W. Hummel, S. Covino +13

We carried out optical observations of the field of the X-ray pulsator RXJ0806.3+1527. A blue V=21.1 star was found to be the only object consistent with the X-ray position. VLT FO…
