WISEPA J174124.26+255319.5 (designation is abbreviated to WISE 1741+2553) is a brown dwarf of spectral class T9,[1][5] located in constellation Hercules at approximately 18 light-years from Earth.[3]

History of observations

Discovery

WISE 1741+2553 was discovered in 2011 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. WISE 1741+2553 has three discovery papers: Scholz et al. (2011), Gelino et al. (2011) and Kirkpatrick et al. (2011).[4][6][1]

Distance

Currently the most accurate distance estimate of WISE 1741+2553 is a trigonometric parallax, measured using Spitzer Space Telescope and published in 2013 by Trent Dupuy and Adam Kraus: 0.180±0.015 arcsec, corresponding to a distance 5.6+0.5
−0.4

Space motion

WISE 1741+2553 has proper motion of about 1553 milliarcseconds per year.[2]

Notes

  1. These 98 brown dwarf systems are only among first, not all brown dwarf systems, discovered from data, collected by WISE: six discoveries were published earlier (however, also listed in Kirkpatrick et al. (2011)) in Mainzer et al. (2011) and Burgasser et al. (2011), and the other discoveries were published later.
  2. Presented in Gelino et al. (2011), but this is not mentioned in Kirkpatrick et al. (2011) and Kirkpatrick et al. (2012) — according these two articles, the only discovery paper of WISE 0750+2725 is Kirkpatrick et al. (2011).
