WISE J071322.55−291751.9 (designation abbreviated to WISE 0713−2917) is a brown dwarf of spectral class Y0, located in constellation Canis Major at approximately 30 light-years from Earth.

Discovery

WISE 0713−2917 was discovered in 2012 by J. Davy Kirkpatrick and colleagues from data collected by the Wide-field Infrared Survey Explorer (WISE) in the infrared at a wavelength of 40 cm (16 in), whose 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 0713−2917.

Distance

Currently the most accurate distance estimate of WISE 0713−2917 is a trigonometric parallax, published in 2014 by Beichman et al.: 0.106 ± 0.013 arcsec, corresponding to a distance of 9.4 ± 1.2 pc (30.7 ± 3.9 ly). An improved parallax was published in 2021, placing WISE 0713−2917 at around 30 light years.

Physical properties

Mass estimates are 19−33 MJ and 13−19 MJ for WISE 0713−2917 depending on the study. No evidence for it being a binary was detected.
