Resolving the Young 2 Cygni Run-away Star into a Binary using iLocater

Justin R. Crepp, Jonathan Crass, Andrew J. Bechter +30

Precision radial velocity (RV) spectrographs that use adaptive optics (AO) show promise to advance telescope observing capabilities beyond those of seeing-limited designs. We are b…

Magellan Adaptive Optics first-light observations of the exoplanet beta Pic b. II. 3-5 micron direct imaging with MagAO+Clio, and the empirical bolometric luminosity of a self-luminous giant planet

Katie M. Morzinski, Jared R. Males, Andy J. Skemer +14

Young giant exoplanets are a unique laboratory for understanding cool, low-gravity atmospheres. A quintessential example is the massive extrasolar planet Pic b, which is 9 AU f…

Deep -band observations of the coolest Y dwarf

Taisiya G. Kopytova, Ian J. M. Crossfield, Niall R. Deacon +7

WISE J085510.83-071442.5 (hereafter, WISE 0855-07) is the coolest Y dwarf known to date and is located at a distance of 2.31 pc, giving it the fourth largest parallax of…
