WebMay 16, 2024 · This is the angle between our line of sight and the orbital axis of the star-exoplanet pair. Maximum amplitude radial velocity variations are seen when the inclination angle is 90 degrees. No radial velocity variations are seen when it is zero. The answer to your question is just that if the inclination angle is close to 90 degrees you will see ... WebNov 9, 2024 · The angle changes by 1/10 of an arcsecond, that changes the radial velocity by something like 500 km/s * sin (1/10 arcsecond) = 0.1 m/s. Maybe a factor 2 more if …
