WISEP J060738.65+242953.4 (designation is abbreviated to W0607+2429[1]:{{{3}}}) is a brown dwarf of spectral class L8,[1]:{{{3}}} located in constellation Gemini at approximately 25 light-years from Earth.[1]:{{{3}}}

Discovery

WISEP J060738.65+242953.4 was discovered in 2012 by Castro & Gizis from data, collected by Wide-field Infrared Survey Explorer (WISE) Earth-orbiting satelliteNASA infrared-wavelength 40 cm (16 in) space telescope, which mission lasted from December 2009 to February 2011. There are also precovery identifications of this object in Two Micron All-Sky Survey (2MASS) data (observation epoch 1998.11) and in the Sloan Digital Sky Survey (SDSS) (DR7) (observation epoch 2006.98).[1]:{{{3}}} In 2012 Castro & Gizis published a paper in The Astrophysical Journal, where they presented discovery of a newfound by WISE L-type brown dwarf WISEP J060738.65+242953.4 (a single discovery, presented in the article).[1]:{{{3}}}

Distance

Trigonometric parallax of WISEP J060738.65+242953.4 is not yet measured. Therefore, there are only distance estimates of this object, obtained by indirect — spectrophotometric — means (see table).

Physical properties

WISEP J060738.65+242953.4 has temperature 1460 ± 90 K and bolometric luminosity 10−4.56 ± 0.09 Solar luminosities (the estimates are based on the object's spectral class (L8)).[3]:{{{3}}} Mass estimates, determined from this temperature, are from 0.03 (for an assumed age 0.5 Gyr) to 0.072 (for an assumed age 10 Gyr) Solar masses, anyway below the hydrogen-burning limit, which implies that WISEP J060738.65+242953.4 is not a true star, but only a substellar object.[3]:{{{3}}}
