Abstract (from CDS):

We report the serendipitous discovery of three very cool distant late type dwarfs. These low-mass stars were found in the 9h- and 16h-fields of the Calar Alto Deep Imaging Survey (CADIS) and named CA09-LMS1, CA16-LMS1 and CA16-LMS2. CA16-LMS1 is the latest object and has a spectral type of >M10 (L1 in the new spectral class L). The other two stars have spectral types of about M9 (CA16-LMS2) and M6.5 (CA09-LMS1). We derive distances of 1150±300pc for CA09-LMS1, 330±80pc for CA16-LMS1, and 120±30pc for CA16-LMS2. The first two of these three objects are probably the most distant late-type M dwarfs for which optical spectra have been obtained.
