SDSS J103931.35 + 325625.5 is a cool object in the Leo Minor constellation . It was first proposed by Chiu et al. (2006) identified as a T1 dwarf by analyzing image data from the Sloan Digital Sky Survey (SDSS) in the near infrared. A spectroscopic study published in 2010 by Burgasser et al. gave strong indications that it could be a binary system with estimated mean spectral types of L7 and T4.
