摘要:
Doppler monitoring of a sample of 1330 stars with a precision of 3 m s−1is discussed. Seventy five planets residing in 65 systems have been discovered within this sample, a detection rate of 5&percent;. Eight multiple systems are found in the sample, and roughly half of the systems with one known planet appear to harbor additional companion(s). The incidence of “hot jupiters”, orbiting within 0.1 AU is 1.0 &percent;. There appears to be a “pile up” of planets at P=3 days. Planets with even shorter periods could easily be detected but none was found indicating they are exceedingly rare. © 2004 American Institute of Physics
