WISEPA J174124.26+255319.5 (designation is abbreviated to WISE 1741+2553) is a brown dwarf of spectral class T9, located in constellation Hercules at 15.0 light-years from Earth.

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).

  • Scholz et al. discovered two late T-type brown dwarfs, including WISE 1741+2553, using preliminary data release from WISE and follow-up near-infrared spectroscopy with LUCIFER1 near-infrared camera/spectrograph at the Large Binocular Telescope (LBT).
  • Gelino et al. examined for binarity nine brown dwarfs using Laser Guide Star Adaptive Optics system (LGS-AO) on Keck II telescope on Mauna Kea; seven of these nine brown dwarfs were also newfound, including WISE 1741+2553. These observations had indicated that two of these nine brown dwarfs are binary, but the other seven, including WISE 1741+2553, are single brown dwarfs.
  • Kirkpatrick et al. 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 1741+2553.
