Characterization of Low-mass Companions to Kepler Objects of Interest Observed with APOGEE-N by Caleb I. Cañas, Chad F. Bender, Suvrath Mahadevan, Dmitry Bizyaev, Nathan De Lee, Scott W. Fleming, Fred Hearty, Steven R. Majewski, Christian Nitschelm, Donald P. Schneider, Javier Serna, Keivan G. Stassun, Guđmundur Stefánsson, Guy S. Stringfellow, John C. Wilson

“…These objects were detected as transiting companions to Sunlike stars (G and F dwarfs) by the Kepler mission and are confirmed as single-lined spectroscopic binaries in the current work using the northern multiplexed Apache Point Observatory Galactic Evolution Experiment near-infrared spectrograph (APOGEE-N) as part of the third and fourth Sloan Digital Sky Surveys. …”
