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 approximately 15.2 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.

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 pc, or 18.1+1.6
−1.4 ly.

Space motion

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

• WISE 0254+0223 (T8)

The other eight objects, checked for binarity by Gelino et al. (2011) on Keck II:

• binarity found:
  • WISE 0458+6434 (T8.5 + T9.5, component A discovered before by Mainzer et al. (2011))
  • WISE 1841+7000 (T5 + T5, newfound)
• binarity not found:
  • WISE 0750+2725 (T8.5, newfound)
  • WISE 1322-2340 (T8, newfound)
  • WISE 1614+1739 (T9, newfound)
  • WISE 1617+1807 (T8, discovered before by Burgasser et al. (2011))
  • WISE 1627+3255 (T6, newfound)
  • WISE 1653+4444 (T8, newfound)

• WISE 1541-2250 — Y0.5 object (44 light-years)
• UGPS 0722−05 — similar T9 object (13 light-years)

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 to these two articles, the only discovery paper of WISE 0750+2725 is Kirkpatrick et al. (2011).
