Radial Velocity Method
Radial Velocity Method is a technique used to detect exoplanets by measuring the periodic changes in the star's radial velocity caused by the gravitational pull of the orbiting planet. This method involves observing the Doppler shift of the star's spectral lines as it moves towards and away from the observer due to the gravitational tug of the planet. By analyzing the periodic variations in the star's radial velocity, astronomers can infer the presence, mass, and orbital characteristics of the exoplanet. This method is particularly effective for detecting massive planets in close orbits around their host stars. However, it is less sensitive to smaller planets and those in more distant orbits.
