We present the first Far Ultraviolet Spectroscopic Explorer (FUSE) spectrum of HD 76534, a Herbig Be star. Here we focus on the analysis of the H2 absorption lines which allow to quantify the gaseous content along the line of sight. This analysis evidences large amounts of cold and warm H2 toward the star. We demonstrate that the H2 is bound to HD 76534 and we argue that it is likely distributed in a circumstellar envelope. In addition, the present study gives clues for the existence of common properties for the circumstellar H2 of Herbig Ae/Be stars.
Key words: stars: circumstellar matter / stars: pre-main sequence / stars: individual: HD 76534
