Career

In 2013, he was a member of a team of scientists that discovered and characterized the extrasolar planet Kepler-64b, a.k.a. PH1, the first planet discovered in a quadruple star system.[3] He showed that suspected transits in the Kepler Space Telescope data of the system were indeed due to a planet transiting the eclipsing binary in the system.[4][5] In 2014, he helped discover and characterize planets in three additional stellar systems, including Kepler-88 and Kepler-247.[6]

He is a core team member of the AAVSO Photometric All-Sky Survey (APASS), a photometric survey of over 100 million stars, providing measurements in eight photometric filters.

Awards and honors

Asteroid 79912 Terrell is named in his honor.[7]
