If an extrasolar planet suddenly became more massive, but kept the same radius and orbit, what would change in the observed Doppler shift of the star?

A) The peak velocity of the star would be faster.
B) The time between peaks in the velocity of the star would decrease.
C) The time between peaks in the velocity of the star would increase.
D) The shape of the velocity curve would become less symmetric.
E) Nothing. The mass of a planet does not affect the Doppler shift.


A) The peak velocity of the star would be faster.
