WISE 0734−7157 [SEP] constellation
WISE 0734−7157
WISE J073444.02−715744.0 (designation abbreviated to WISE 0734−7157) is a brown dwarf of spectral class Y0, located in constellation Volans at approximately 35 light-years from Earth. It is one of the furthest Y0 brown dwarfs known.
Discovery.
WISE 0734−7157 was discovered in 2012 by J. Davy Kirkpatrick et al. from data, collected by Wide-field Infrared Survey Explorer (WISE) Earth-orbiting satellite — NASA infrared-wavelength 40 cm (16 in) space telescope, which mission lasted from December 2009
to February 2011. In 2012 Kirkpatrick et al. published a paper in The Astrophysical Journal, where they presented discovery of seven new found by WISE brown dwarfs of spectral type Y, among which also was WISE 0734−7157.
Distance.
Trigonometric parallax of WISE 0734−7157 is not yet measured. Therefore, there are only distance estimates of this object, obtained by indirect — spectrofotometric — means (see table).
