Question:
A planet has been discovered orbiting the sunlike star HD From
the period and velocity measured by the Doppler method, its mass was
calculated to be times that of Jupiter. The plane of the planets orbit is
edgeon and it has been observed to transit across the face of the star. The
light from the star was seen to drop by when the planets disc lay fully
within that of the star which has a radius of km Assuming that
the brightness of the star is constant across the observed face, estimate
the diameter of the planet and hence it density in comparison with that of
Jupiter which has a radius of km
