Spitzer + Hubble Space Telescope Parallaxes of 13 Late T and Y Dwarfs

We present astrometric measurements for 13 cold brown dwarfs in the solar neighborhood ( d  <  20 pc). By combining archival Spitzer data with our own Hubble Space Telescope (HST) observations, we achieve parallax uncertainties typically around 10%. Using Spitzer and HST photometry we compare our ta...
