Despite averagely high temperature (8600 K) and small radius (>0.03 RSol) light curve models exclude the possibility of a thermal white dwarf irradiator for the substellar companion. Temperature on irradiated dayside exceeds 10000 K whereas nightside, despite cooler (<6500 K), appears way hotter than any irradiated brown dwarf or Hot Jupiter-type exoplanet.
