  • We present infrared JHK photometry of the cataclysmic variable (CV) SDSS J123813.73 - 033933.0 and analyze it along with optical spectroscopy, demonstrating that the binary system is most probably comprised of a massive white dwarf with T{sub eff} = 12000 +- 1000 K and a brown dwarf of spectral type L4. The inferred system parameters suggest that this system may have evolved beyond the orbital period minimum and is a bounce-back system. SDSS J123813.73 - 033933.0 stands out among CVs by… CONTINUE READING
