Samantha Trumbo ’13, a doctoral student in planetary science at the California Institute of Technology, will follow up on this breakthrough discovery, which she made using data from the Hubble Space Telescope, as a 51 Pegasi b Fellow hosted by the astronomy department in the College of Arts and Sciences (A&S).
