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.
.
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.

The Doppler method allows astronomers detect planets around other stars by observing what? a. the light from the planet that is moving towards the star b. the light from the planet that is orbiting around the center of mass c. the light from the star that is wobbling around the center of mass d. the light from the star that is moving away from the planet
B Resources C. Give Up? Feedback Astronomers discover an exoplanet, a planet obriting a star other than the Sun, that has an orbital period of 3.03 Earth years in a circular orbit around its star, which has a measured mass of 3.01 x 10kg. Find the radius r of the exoplanet's orbit. 4.65 x1034 m Incorrect Artificial gravity is a must for any space station if humans are to live there for any extended length of time. Without artificial gravity,...

If an experimenter wants to use the GFP method but needs to detect the presence or absence of several proteins at the same time, he can take advantage of mutational variants of GFP that emit what light? Select all that apply. Select all that apply. red cyan yellow blue green
Explain how the presence of externalities can affect the valuation of social projects. How would you go about monetizing an external cost such as environmental cost in a social project evaluation? Use an example to explain your response
What kinds of situations are likely to lead to an overjustification effect? How can knowledge of this effect be used to try to increase a child’s intrinsic motivation for school? How can knowledge of this effect be used to increase workers’ productivity?
D Question 3 2 pts When and how does the RT-PCR test detect the presence of the virus? After PCR, by adding a quencher dye which is activated when the viral DNA is available in high concentrations During PCR by adding fluorescent primers that are detected through a special laser After PCR, by adding a fluorescent dye which will be activated once the sample goes through a special laser. During PCR, by adding a fluorescent dye and a quencher dye...
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...
