3. Formation of super-Earths via pebble accretion onto planetesimals
University essay from Lunds universitet/Astronomi - Genomgår omorganisationAbstract : Data from NASA's Kepler space telescope, which searches for exoplanets via the transit method, produced 1108 new planetary candidates in 2013 with a total of 91% being smaller than Neptune in size.
