We identify candidate hypervelocity stars from the Sloan Extension for
Galactic Understanding and Exploration (SEGUE) G and K dwarf samples.
Previous searches for hypervelocity stars have only focused on large
radial velocities; in this study we also use proper motions to select
the candidates. We determine the hypervelocity likelihood of each
candidate, considering the significant errors often associated with high
proper motion stars via Monte Carlo simulations. Using the observed 6-d
positions and velocities, we also calculate the orbits of these
candidates in order to determine their place of origin within the
Galaxy.
