Planet-Finding Campaign Reveals That Gas-Giant Exoplanets Orbit Close to Their Parent Stars

New Study Reveals That Gas Giant Exoplanets Stay Close to Their Parent Stars

Using data from Gemini Observatory’s Planet-Finding Campaign, several new studies reveal the nature of gas-giant exoplanets, finding that they tend to dwell near their parent stars. Finding extrasolar planets has become so commonplace that it seems astronomers merely have to look up and another world is discovered. However, results from Gemini Observatory’s recently completed Planet-Finding […]
