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 [[arcsecond|arcsec]], corresponding to a distance of {{cvt|9.4|±|1.2|pc|ly|lk=on}}.{{r|Beichman2014}} An improved parallax was published in 2021, placing WISE 0713−2917 at around 30 light years.{{r|Kirkpatrick21}}
[[Trigonometric parallax]] of WISE 0713−2917 is not yet measured. Therefore, there are only distance estimates of this object, obtained by indirect—spectrophotometric—means (see table).

WISE J071322.55−291751.9 (designation abbreviated to WISE 0713−2917) is a brown dwarf of spectral class Y0,[1] located in constellation Canis Major at approximately 30 light-years from Earth.[3]

Discovery[edit]

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.[1]

Distance[edit]

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).[3] An improved parallax was published in 2021, placing WISE 0713−2917 at around 30 light years.[2]

Physical properties[edit]

Mass estimates are 19−33 MJ[4] and 13−19 MJ[5] for WISE 0713−2917 depending on the study. No evidence for it being a binary was detected.[4]
