A Search for L/T Transition Dwarfs With Pan-STARRS1 and WISE. III. Young L Dwarf Discoveries and Proper Motion Catalogs in Taurus and Scorpius-Centaurus
William M. J. Best, Michael C. Liu, Eugene A. Magnier +13
We present the discovery of eight young M7-L2 dwarfs in the Taurus star-forming region and the Scorpius-Centaurus OB Association, serendipitously found during a wide-field search f…
Brown Dwarfs in Young Moving Groups from Pan-STARRS1. I. AB Doradus
Kimberly M. Aller, Michael C. Liu, Eugene A. Magnier +11
Substellar members of young (150 Myr) moving groups are valuable benchmarks to empirically define brown dwarf evolution with age and to study the low-mass end of the init…
Characterizing Phishing Threats with Natural Language Processing
Michael C. Kotson, Alexia Schulz
Spear phishing is a widespread concern in the modern network security landscape, but there are few metrics that measure the extent to which reconnaissance is performed on phishing…
Planets Around Low-Mass Stars (PALMS). V. Age-Dating Low-Mass Companions to Members and Interlopers of Young Moving Groups
Brendan P. Bowler, Evgenya L. Shkolnik, Michael C. Liu +22
We present optical and near-infrared adaptive optics (AO) imaging and spectroscopy of 13 ultracool (>M6) companions to late-type stars (K7-M4.5), most of which have recently been i…
A Study of the Shortest-Period Planets Found With Kepler
Roberto Sanchis-Ojeda, Saul Rappaport, Joshua N. Winn +3
We present the results of a survey aimed at discovering and studying transiting planets with orbital periods shorter than one day (ultra--short-period, or USP, planets), using data…
The Extremely Red, Young L Dwarf PSO J318-22: A Free-Floating Planetary-Mass Analog to Directly Imaged Young Gas-Giant Planets
Michael C. Liu, Eugene A. Magnier, Niall R. Deacon +16
We have used Pan-STARRS1 to discover an extremely red late-L dwarf, which has (J-K)_MKO = 2.84 and (J-K)_2MASS = 2.78, making it the reddest known field dwarf and second only to 2M…
Transits and Occultations of an Earth-Sized Planet in an 8.5-Hour Orbit
Roberto Sanchis-Ojeda, Saul Rappaport, Joshua N. Winn +4
We report the discovery of an Earth-sized planet () in an 8.5-hour orbit around a late G-type star (KIC 8435766, Kepler-78). The object was identified in a s…
