How can astronomers use the Doppler Effect to detect the presence of an exoplanet around a star? Try to be as clear as possible about what is measured and how that is interpreted.

Homework Answers
Doppler effect is a technique for discovering exoplanets as it is used to analyze the motion and properties of stars and planets. Both these are orbiting a common centre of mass that means the stars and planets are gravitationally one other causing them to orbit around a point of mass central to both the bodies. The relative speed of stars moving towards or away from the sun as detected through the doppler effect which gives clue to the suns motion through the milky way galaxy as well as other information about the motion of stars that includes its cluster and as gas clouds in space.

Problem in Modren physics
Question :Suppose that you'd like to find out if adistant star is moving relative to the earth. The star is much toofar away to detect any change in its brightness as itmoves towardor away from the earth. Instead we can use the Doppler effect todetermine its relative speed. For this problem we are going to lookat the spectrallines from hydrogen, specifically the one with awavelength of 656.46 nm.(A)Suppose that you measure the light ofa star between 640 and 680 nm...
