Abstract

We present near-infrared JHK s photometry and light curves of the candidate magnetic white dwarf+brown dwarf binary SDSS J121209.31+013627.7 and report on the detection of near-infrared excess and variability in the K s band. The observed near-infrared excess can be explained by the presence of an L...
