Optically bright Galactic stars (V < 13 mag) having fv(24 um) > 1 mJy areidentified in Spitzer mid-infrared surveys within 8.2 square degrees for theBootes field of the NOAO Deep Wide-Field Survey and within 5.5 square degreesfor the First Look Survey (FLS). 128 stars are identified in Bootes and 140 inthe FLS, and their photometry is given. (K-[24]) colors are determined using Kmagnitudes from the 2MASS survey for all stars in order to search for excess 24um luminosity compared to that arising from the stellar photosphere. Of thecombined sample of 268 stars, 141 are of spectral types F, G, or K, and 17 ofthese 141 stars have 24 um excesses with (K-[24]) > 0.2 mag. Using limits onabsolute magnitude derived from proper motions, at least 8 of the FGK starswith excesses are main sequence stars, and estimates derived from thedistribution of apparent magnitudes indicate that all 17 are main sequencestars. These estimates lead to the conclusion that between 9% and 17% of themain sequence FGK field stars in these samples have 24 um infrared excesses.This result is statistically similar to the fraction of stars with debris disksfound among previous Spitzer targeted observations of much brighter, mainsequence field stars.
