Detection of an exoplanet by radial velocity - Detection of an exoplanet: Radial velocity or Doppler method - This detection method is based on the study of the light spectrum of the star. A planet orbiting around a star periodically influences the movement of that star. By Doppler effect (the star's light wave shifts to blue when it approaches and decals to red when it moves away), we can measure the radial velocity of the star and know the position of the planet's orbit. An exoplanet orbiting a larger star could produce changes in position and velocity of the star as they orbit their common center of mass. Those variations in the radial velocity are known in studying the spectral lines of the star due to the Doppler effect (blue shift when the star is approaching, redshift when it is receding)

An exoplanet orbiting a larger star could produce changes in position and velocity of the star as they orbit their common center of mass. Those variations in the radial velocity are known in studying the spectral lines of the star due to the Doppler effect (blue shift when the star is approaching, redshift when it is receding)

PIX4573959: Detection of an exoplanet by radial velocity - Detection of an exoplanet: Radial velocity or Doppler method - This detection method is based on the study of the light spectrum of the star. A planet orbiting around a star periodically influences the movement of that star. By Doppler effect (the star's light wave shifts to blue when it approaches and decals to red when it moves away), we can measure the radial velocity of the star and know the position of the planet's orbit.
