... 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. ...

17. How Charge Transfer Traps Affect Photometric and Astrometric Results
... The object just above trap 2-637 in Figure 5 is a good example of how traps can affect the observations of point sources. ... In the case of the object above trap 2-637, the photometric magnitude measured within a 6-pixel aperture (i.e., radius = 3 pixels) is about 0.1 mag fainter than it should be, due to the tail taking light out of the aperture. The FWHM is increased from 1.5 pixels to 2.2 pixels. ... Another relevant question is what percentage of objects are affected by charge transfer traps. ...
