摘要

The first three extrasolar planets orbiting Solar-like stars have recently been discovered. All three were inferred from a periodicity in the optical Doppler measurements of their host stars, indicating a reflex motion in response to the gravitational force exerted by the planets. From such measurements and standard Newtonian physics, one may infer the orbital period and value of M$-PL$/ sin i of 0.46, 2.5 and 6.5 M$-JUP$/, and orbital periods of 4.2, 117 and 1100 days, respectively. The most massive planet (around 70 Vir) has an eccentricity, e $EQ 0.38, larger than any in our Solar System, and one (around 51 Peg) has an orbital radius of 0.05 AU which is smaller than any in our Solar System. A general theory for the formation of planets must include these new characteristics.
