The Doppler Dance: How Radial Velocity Reveals Exoplanets

A deep dive into how astronomers detect planets around other stars by watching tiny wobbles in starlight. We explain the Doppler shift, radial velocity measurements, and the quest from the first hot Jupiter 51 Pegasi b to the centimeter-per-second precision of HARPS. We'll cover the M sin I mass ambiguity, the challenge of stellar noise, and how combining radial velocity with transits unlocks true planet masses. Finally, we glimpse the future with Espresso and Codex and the race toward true Earth analogs in the habitable zone.
