How is radial velocity (RV) used to discover exoplanets? Episode 38 Planet Hunters 2022-05-24 | Planet Hunters Coffee Chat is back! Welcome to our 38th episode.We hope you've had a relaxing break from exoplanet science (Nora definitely needs one of those now she's finished writing her thesis!)Today, we're learning about another method used to detect exoplanets, called radial velocity (RV). You'll have heard us mention this in previous episodes but in this episode, we're getting into the nitty-gritty and calculating an exoplanet's mass.Download the code from our website here: https://www.planethunters.coffee/steps-to-identifying-a-planetYou can get radial velocity data from the ESO Archive here: http://archive.eso.org/cms.htmlFor the star's mass, head to ExoFOP: https://exofop.ipac.caltech.edu/tess/As always, if you have any questions about Planet Hunters or this series, check out the Planet Hunters TESS Talk forum: zooniverse.org/projects/nora-dot-eisner/planet-hunters-tessOr feel free to ask questions in the comments, we answer as many as we can.
