Scientific paper

According to its new Hipparcos parallax, the star Beta Pictoris is farther away and hence more luminous than previously believed. In the HR diagram, the star is now very close to, or on the ZAMS, instead of being clearly below it. The consequences are threefold: (i) all evaluated geometrical dimensions of the Beta Pictoris circumstellar disks are larger by about 20 per cent; (ii) there is no more need for any intrinsic circumstellar extinction due to the dust disk seen edge-on, in agreement with the amount of dust directly detected through stellar coronography; (iii) the stellar age has to be of at least 8 Myr and is more probably on the order of 100 Myr, again compatible with the fact that this circumstellar disk seems to be `post' planetary and certainly not `proto' planetary.
