Homework Statement
The precision in measurements of radial velocities by the Doppler effect is currently 1 m/s.Can a Jupiter like planet orbiting a star similar to the Sun at a distance from the mother star equal to the Sun-Jupiter distance be detected?'
(Use www or other sources to find the mass of Jupiter, the Sun and the distance between the two which are the only data you are allowed to use).
Ms = 1.989*10^30 kg
Mj = 1.898*10^27 kg
d = 778500000 km
Homework Equations
|vr|= v sin(i), where
vr is the radial velocity
v is the real velocity
and i is the inclination of the orbit.
a*/ap = v*/vp = v*r/vpr
where a* and ap are the semimajor axis of the sun and the planet.
Kepler's 3. low can maybe be usefull.
