Trigonometric parallaxes of two T dwarfs with Keck and ShaneAO astrometry
Jayke Nguyen, S. Mark Ammons, Kaitlin Dennison +4
We present trigonometric parallax and proper motion measurements for two T-type brown dwarfs. We derive our measurements from infrared laser guide star adaptive optics observations…
