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…
On the Morphology and Chemical Composition of the HR 4796A Debris Disk
Timothy J. Rodigas, Christopher C. Stark, Alycia Weinberger +17
[abridged] We present resolved images of the HR 4796A debris disk using the Magellan adaptive optics system paired with Clio-2 and VisAO. We detect the disk at 0.77 \microns, 0.91…
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 …
Status Update and Closed-Loop Performance of the Magellan Adaptive Optics VisAO Camera
Derek Kopon, Laird M. Close, Jared Males +3
We present laboratory results of the closed-loop performance of the Magellan Adaptive Optics (AO) Adaptive Secondary Mirror (ASM), pyramid wavefront sensor (PWFS), and VisAO visibl…
Direct imaging of exoplanets in the habitable zone with adaptive optics
Jared R. Males, Laird M. Close, Olivier Guyon +16
One of the primary goals of exoplanet science is to find and characterize habitable planets, and direct imaging will play a key role in this effort. Though imaging a true Earth ana…
MagAO: Status and on-sky performance of the Magellan adaptive optics system
Katie M. Morzinski, Laird M. Close, Jared R. Males +19
MagAO is the new adaptive optics system with visible-light and infrared science cameras, located on the 6.5-m Magellan "Clay" telescope at Las Campanas Observatory, Chile. The inst…
Into the Blue: AO Science with MagAO in the Visible
Laird M. Close, Jared R. Males, Katherine B. Follette +11
We review astronomical results in the visible (λ<1μm) with adaptive optics. Other than a brief period in the early 1990s, there has been little astronomical science done in the vis…
High contrast imaging at the LBT: the LEECH exoplanet imaging survey
Andrew J. Skemer, Philip Hinz, Simone Esposito +34
In Spring 2013, the LEECH (LBTI Exozodi Exoplanet Common Hunt) survey began its 130-night campaign from the Large Binocular Telescope (LBT) atop Mt Graham, Arizona. This surv…
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…
The Gemini NICI Planet-Finding Campaign: The Orbit of the Young Exoplanet beta Pictoris b
Eric L. Nielsen, Michael C. Liu, Zahed Wahhaj +12
We present new astrometry for the young (12--21 Myr) exoplanet beta Pictoris b taken with the Gemini/NICI and Magellan/MagAO instruments between 2009 and 2012. The high dynamic ran…
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…
LEECH: A 100 Night Exoplanet Imaging Survey at the LBT
Andrew Skemer, Daniel Apai, Vanessa Bailey +29
In February 2013, the LEECH (LBTI Exozodi Exoplanet Common Hunt) survey began its 100-night campaign from the Large Binocular Telescope atop Mount Graham in Arizona. LEECH nearly c…
