Abstract
At V = 14.65, GD 190 is a fairly bright classical DB star with an effective temperature slightly above 20,000 K. Its optical spectrum, characterized by strong He I lines, was the first one observed to show the forbidden λ4517 component. For the past twenty years, the object has been included in numerous photometric and spectroscopic analyses in the optical, and it has recently been observed with the GHRS by Provencal et al. (2000): the far-ultraviolet spectrum features photospheric C I and C II transitions amenable to abundance analyses. The object was included last year in the photometric calibration program of the FUSE satellite. We present here the ultraviolet spectrum secured, as well as a preliminary survey of its content.
