Question
The 2019 Nobel Prize in Physics was awarded to Michel Mayor and Didier Queloz for the first discovery of these objects. For 10 points each:
[10e] These objects were often found using the radial velocity method, which detects changes in a star’s radial velocity as it is affected by the gravity of these objects. Super-Earths are one type of these objects.
ANSWER: exoplanets [accept extrasolar planets; prompt on planets]
[10m] Today, this method is more commonly used to detect exoplanets. This method used by the Kepler mission can wrongly detect white and brown dwarfs as well since it finds an exoplanet’s radius but not its mass.
ANSWER: transit photometry
[10h] This star, located in the constellation Aquarius, has seven known exoplanets that were detected using transit photometry by an organization with the same name.
ANSWER: TRAPPIST-1 [accept Transiting Planets and Planetesimals Small Telescope]
