      A method is defined for identifying late-T and Y dwarfs in WISE down to low values of signal-to-noise. This requires a WISE detection only in the W2-band and uses the statistical properties of the WISE multiframe measurements ...

    • Primeval very low-mass stars and brown dwarfs -- VIII. The first age benchmark L subdwarf, a wide companion to a halo white dwarf 

      Zhang, Z. H.; Raddi, R.; Burgasser, A. J.; Casewell, S. L.; Smart, R. L.; Galvez-Ortiz, M. C.; Jones, H. R. A.; Baig, S.; Lodieu, N.; Gauza, B.; Pavlenko, Ya V.; Jiao, Y. F.; Zhao, Z. K.; Zhou, S. Y.; Pinfield, D. J. (2024-09-01)
      We report the discovery of five white dwarf + ultracool dwarf systems identified as common proper motion wide binaries in the Gaia Catalogue of Nearby Stars. The discoveries include a white dwarf + L subdwarf binary, VVV ...
