ASPITZERSEARCH FOR PLANETARY-MASS BROWN DWARFS WITH CIRCUMSTELLAR DISKS: CANDIDATE SELECTION
2010
Astrophysical Journal
We report on initial results from a Spitzer program to search for very low-mass brown dwarfs in Ophiuchus. This program is an extension of an earlier study by Allers et al. which had resulted in an extraordinary success rate, 18 confirmed out of 19 candidates. Their program combined near-infrared and Spitzer photom- etry to identify objects with very cool photospheres together with circumstellar disk emission to indicate youth. Our new program has obtained deep IRAC pho- tometry of a 0.5 deg2
