J. Davy Kirkpatrick is an American astronomer at the Infrared Processing and Analysis Center at the California Institute of Technology in Pasadena, California. Kirkpatrick's research was named one of the top ten science accomplishments of the first ten years (1992–2002) of the W. M. Keck Observatory and one of the Top 100 Stories of 2011 by Discover Magazine.
Kirkpatrick received a BS in mathematics and physics/astronomy from Vanderbilt University in 1986 and a PhD in astronomy from the University of Arizona in 1992. He was a W. J. McDonald Fellow at the University of Texas at Austin from 1992-1994, a National Research Council Fellow at JPL from 1994-1996, and a NICMOS Fellow at UCLA from 1996-1997 before being hired at Caltech, where he works today.
Much of Kirkpatrick's research has concentrated on the discovery and characterization of the lowest mass stars and brown dwarfs. After refining the far optical and near-infrared classifications of M dwarfs in the early 1990s and publishing the first spectrum of the brown dwarf candidate GD 165B, which would later be referred to as the first L dwarf discovery, Kirkpatrick joined the Two Micron All-Sky Survey (2MASS) team to search for even colder objects. Along with Neill Reid, he uncovered many objects similar to and colder than GD 165B, leading to the definition of the L dwarfspectral class. Also using 2MASS data, he and graduate student Adam Burgasser discovered brown dwarfs even colder than spectral class L, leading to the establishment of the T dwarf spectral class. More recently, as a member of the Wide-field Infrared Survey Explorer (WISE) team, Kirkpatrick and his research group have uncovered even colder brown dwarfs, leading to the establishment, with postdoc Michael Cushing, of the Y dwarf spectral class.
