History of observations
Discovery
WISE 1741+2553 was discovered in 2011 from data, collected by Wide-field Infrared Survey Explorer Earth-orbiting satellite—NASA infrared-wavelength 40 cm space telescope, which mission lasted from December 2009 to February 2011. WISE 1741+2553 has three discovery papers: Scholz et al. , Gelino et al. and Kirkpatrick et al. .- 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 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 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.
