WISEPA J171104.60+350036.8 (designation abbreviated to WISE 1711+3500, or WISE J1711+3500) is a brown dwarf of spectral class T8,[1][2] located in constellation Hercules at approximately 60 light-years from Earth.[2]
Discovery
[edit]WISE 1711+3500 was discovered in 2011 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 2011 Kirkpatrick et al. published a paper in The Astrophysical Journal Supplement, where they presented discovery of 98 new found by WISE brown dwarf systems with components of spectral types M, L, T and Y, among which also was WISE 1711+3500.[1][note 1]
Distance
[edit]Trigonometric parallax of WISE 1711+3500 is not yet measured. Therefore, there are only distance estimates of this object, obtained by indirect — spectrofotometric — means (see table).
WISE 1711+3500 distance estimates
| Source | Parallax, mas | Distance, pc | Distance, ly | Ref. |
|---|---|---|---|---|
| Kirkpatrick et al. (2011) | ~17.0 | ~55.4 | [1] | |
| Kirkpatrick et al. (2012) | ~18.5 | ~60.3 | [2] |
Non-trigonometric distance estimates are marked in italic.
Notes
[edit]- ^ This 98 brown dwarf systems are only among first, not all brown dwarf systems, discovered from data, collected by WISE: six discoveries was published earlier (however, also listed in Kirkpatrick et al. (2011)) in Mainzer et al. (2011) and Burgasser et al. (2011), and the other discoveries was published later.
