    • The brightest pure-H ultracool white dwarf 

      Catalan, S.; Tremblay, P. -E.; Pinfield, D.J.; Smith, Leigh; Zhang, Z. H.; Napiwotzki, R.; Marocco, F.; Day-Jones, A. C.; Gomes, J.; Forde, K.P.; Lucas, P.W.; Jones, H.R.A. (2012-10)
      We report the identification of LSR J0745+2627 in the United Kingdom InfraRed Telescope Infrared Deep Sky Survey (UKIDSS) Large Area Survey (LAS) as a cool white dwarf with kinematics and age compatible with the thick-disk/halo ...
    • Discovery of shocked H-2 around OH 231.8+4.2 

      Forde, K.P.; Gledhill, T. (2012-03)
      We present K-band integral field observations of the circumstellar envelope of the evolved star OH 231.8+4.2. Spatial and spectral information was simultaneously acquired using the SINFONI integral field unit, with adaptive ...
    • A fast bipolar H2 outflow from IRAS 16342-3814 : An old star reliving its youth 

      Gledhill, T.; Forde, K.P. (2012-03)
      Some evolved stars in the pre-planetary nebula phase produce highly collimated molecular outflows that resemble the accretion-driven jets and outflows from pre-main-sequence stars. We show that IRAS 16342-3814 (the Water ...
    • Integral field spectroscopy of H-2 and CO emission in IRAS 18276-1431 : evidence for ongoing post-AGB mass-loss 

      Gledhill, T.; Forde, K.P.; Lowe, Krispian; Smith, M.D. (2011)
      We present K-band integral field spectroscopy of the bipolar post-asymptotic giant branch (post-AGB) object IRAS 18276-1431 (OH 17.7-2.0) using SINFONI on the VLT. This allows us to image both the continuum and molecular ...
