New Spatially Resolved Imaging of the SR 21 Transition Disk and Constraints on the Small-Grain Disk Geometry
Steph Sallum, Andy Skemer, Josh Eisner +9
We present new 0.6 - 4 m imaging of the SR 21 transition disk from Keck/NIRC2 and Magellan/MagAO. The protoplanetary disk around SR 21 has a large (~ 30 - 40 AU) clearing first…
The HOSTS survey - Exozodiacal dust measurements for 30 stars
S. Ertel, D. Defrère, P. Hinz +40
The HOSTS (Hunt for Observable Signatures of Terrestrial Systems) survey searches for dust near the habitable zones (HZs) around nearby, bright main sequence stars. We use nulling…
High Contrast Imaging in the Visible: First Experimental Results at the Large Binocular Telescope
F. Pedichini, M. Stangalini, A. Ambrosino +13
In February 2014, the SHARK-VIS (System for High contrast And coronography from R to K at VISual bands) Forerunner, a high contrast experimental imager operating at visible wavelen…
Exoplanet science with the LBTI: instrument status and plans
D. Defrère, P. Hinz, A. Skemer +21
The Large Binocular Telescope Interferometer (LBTI) is a strategic instrument of the LBT designed for high-sensitivity, high-contrast, and high-resolution infrared (1.5-13 m) im…
First-light LBT nulling interferometric observations: warm exozodiacal dust resolved within a few AU of eta Corvi
D. Defrère, P. M. Hinz, A. J. Skemer +37
We report on the first nulling interferometric observations with the Large Binocular Telescope Interferometer (LBTI), resolving the N' band (9.81 - 12.41 um) emission around the ne…
The LEECH Exoplanet Imaging Survey. Further constraints on the planet architecture of the HR 8799 system
A. -L. Maire, A. J. Skemer, P. M. Hinz +36
Context. Astrometric monitoring of directly-imaged exoplanets allows the study of their orbital parameters and system architectures. Because most directly-imaged planets have long…
Discovery of H-alpha Emission from the Close Companion Inside the Gap of Transitional Disk HD142527
L. M. Close, K. B. Follette, J. R. Males +10
We utilized the new high-order 585 actuator Magellan Adaptive Optics system (MagAO) to obtain very high-resolution visible light images of HD142527 with MagAO's VisAO science camer…
Characterization of the gaseous companion κ Andromedae b: New Keck and LBTI high-contrast observations
M. Bonnefoy, T. Currie, G. -D. Marleau +64
We previously reported the direct detection of a low mass companion at a projected separation of 55+-2 AU around the B9 type star κ Andromedae. The properties of the system (mass r…
Discovery of a probable 4-5 Jupiter-mass exoplanet to HD 95086 by direct-imaging
J. Rameau, G. Chauvin, A. -M. Lagrange +13
Direct imaging has just started the inventory of the population of gas giant planets on wide-orbits around young stars in the solar neighborhood. Following this approach, we carrie…
