... More on 51 Peg: . The discovery of a Jupiter--mass planet in orbit around the solar--type star 51Peg has been reported by Michel Mayor and Didier Queloz (Geneva Observatory) on October 6th at the 9th Cambridge workshop on "cool stars, stellar systems, and the sun" held at Florence (Italy). ... Recall that the measurements of radial velocity only yield v sin i which in turn gives us M sin i. For most values of i, sin i will be greater than 0.5 and this gives a mass estimate of 0.5 Jupiter masses. ...

8. A Little About How HST and GHRS Work
... Because of the difficulties of working with and communicating with a satellite in low-earth orbit, and in order to make HST more efficient, virtually all actions taken by the spacecraft are planned weeks in advance. Only a small fraction of HST's time can be used for real-time actions that are at the discretion of the observer, and even then the only possible action is deciding which object in the field should be centered in the aperture before a subsequent observation is begun. ...
