ASTR 103 Lecture Notes - Lecture 29: Radial Velocity
Document Summary
Difficult to detect because they are lost in the glare of the star they orbit, and are too close to the star to resolve. Looking for irregularities in the periods and amplitudes of pulsar energy pulses. Looking for doppler shift in a star"s spectral lines caused by star wobble. Many of the planets that have been discovered using the radial velocity technique are far larger and far closer than our theories on planetary formation. Seeing direct light (usually in ir or near ir) from an exoplanet. Light intensity of the star varies as the planet temporarily blocks its surface.
