If an extrasolar planet suddenly became larger in radius, but kept the same mass and orbit, what would change in the observed Doppler shift of the star?
A) Nothing. The radius of a planet does not affect the Doppler shift.
B) The time between peaks in the velocity of the star would decrease.
C) The peak velocity of the star would be faster.
D) The shape of the velocity curve would become less symmetric.
E) The lowest velocity of the star would be slower.
