Exo-zodi modelling for the Large Binocular Telescope Interferometer

Grant M. Kennedy, Mark C. Wyatt, Vanessa Bailey +18

Habitable zone dust levels are a key unknown that must be understood to ensure the success of future space missions to image Earth analogues around nearby stars. Current detection…

HATS-6b: A Warm Saturn Transiting an Early M Dwarf Star, and a Set of Empirical Relations for Characterizing K and M Dwarf Planet Hosts

J. D. Hartman, D. Bayliss, R. Brahm +25

We report the discovery by the HATSouth survey of HATS-6b, an extrasolar planet transiting a V=15.2 mag, i=13.7 mag M1V star with a mass of 0.57 Msun and a radius of 0.57 Rsun. HAT…

An Enigmatic Pointlike Feature within the HD 169142 Transitional Disk

Beth A. Biller, Jared Males, Timothy Rodigas +13

We report the detection of a faint pointlike feature possibly related to ongoing planet-formation in the disk of the transition disk star HD 169142. The pointlike feature has a …

GJ 832c: A super-earth in the habitable zone

R. A. Wittenmyer, Mikko Tuomi, R. P. Butler +17

We report the detection of GJ 832c, a super-Earth orbiting near the inner edge of the habitable zone of GJ 832, an M dwarf previously known to host a Jupiter analog in a nearly-cir…

Two planets around Kapteyn's star : a cold and a temperate super-Earth orbiting the nearest halo red-dwarf

Guillem Anglada-Escudé, Pamela Arriagada, Mikko Tuomi +21

Exoplanets of a few Earth masses can be now detected around nearby low-mass stars using Doppler spectroscopy. In this paper, we investigate the radial velocity variations of Kaptey…

Magellan Adaptive Optics first-light observations of the exoplanet Pic b. I. Direct imaging in the far-red optical with MagAO+VisAO and in the near-IR with NICI

Jared R. Males, Laird M. Close, Katie M. Morzinski +20

We present the first ground-based CCD (m) image of an extrasolar planet. Using MagAO's VisAO camera we detected the extrasolar giant planet (EGP) Pictoris b in -short…
