Ground-based adaptive optics coronagraphic performance under closed-loop predictive control
Jared R. Males, Olivier Guyon
The discovery of the exoplanet Proxima b highlights the potential for the coming generation of giant segmented mirror telescopes (GSMTs) to characterize terrestrial --- potentially…
The TWA 3 Young Triple System: Orbits, Disks, Evolution
Kendra Kellogg, L. Prato, Guillermo Torres +14
We have characterized the spectroscopic orbit of the TWA 3A binary and provide preliminary families of probable solutions for the TWA 3A visual orbit as well as for the wide TWA 3A…
Adaptive Optics Predictive Control with Empirical Orthogonal Functions (EOFs)
Olivier Guyon, Jared Males
Atmospheric wavefront prediction based on previous wavefront sensor measurements can greatly enhance the performance of adaptive optics systems. We propose an optimal linear approa…
Spectral Linear Dark Field Control: Stabilizing Deep Contrast for Exoplanet Imaging Using out-of-band Speckle Field
Olivier Guyon, Kelsey Miller, Jared Males +2
Wavefront stabilization is a fundamental challenge to high contrast imaging of exoplanets. For both space and ground observations, wavefront control performance is ultimately limit…
The Multiplicity of M-Dwarfs in Young Moving Groups
Yutong Shan, Jennifer C. Yee, Brendan P. Bowler +11
We image 104 newly identified low-mass (mostly M-dwarf) pre-main sequence members of nearby young moving groups with Magellan Adaptive Optics (MagAO) and identify 27 binaries with…
Resolving the H-alpha-emitting Region in the Wind of Eta Carinae
Ya-Lin Wu, Nathan Smith, Laird M. Close +2
The massive evolved star Eta Carinae is the most luminous star in the Milky Way and has the highest steady wind mass-loss rate of any known star. Radiative transfer models of the s…
An Optical/near-infrared investigation of HD 100546 b with the Gemini Planet Imager and MagAO
Julien Rameau, Katherine B. Follette, Laurent Pueyo +52
We present H band spectroscopic and Halpha photometric observations of HD 100546 obtained with GPI and MagAO. We detect H band emission at the location of the protoplanet HD 100546…
Complex Spiral Structure in the HD 100546 Transitional Disk as Revealed by GPI and MagAO
Katherine B. Follette, Julien Rameau, Ruobing Dong +53
We present optical and near-infrared high contrast images of the transitional disk HD 100546 taken with the Magellan Adaptive Optics system (MagAO) and the Gemini Planet Imager (GP…
Spatial Linear Dark Field Control: Stabilizing Deep Contrast for Exoplanet Imaging Using Bright Speckles
Kelsey Miller, Olivier Guyon, Jared R Males
Direct imaging of exoplanets requires establishing and maintaining a high contrast dark field (DF) within the science image to a high degree of precision (10^-10). Current approach…
On-sky performance analysis of the vector Apodizing Phase Plate coronagraph on MagAO/Clio2
Gilles P. P. L. Otten, Frans Snik, Matthew A. Kenworthy +9
We report on the performance of a vector apodizing phase plate coronagraph that operates over a wavelength range of m and is installed in MagAO/Clio2 at the 6.5 m Magellan C…
An ALMA and MagAO Study of the Substellar Companion GQ Lup B
Ya-Lin Wu, Patrick D. Sheehan, Jared R. Males +6
Multi-wavelength observations provide a complementary view of the formation of young directly-imaged planet-mass companions. We report the ALMA 1.3 mm and Magellan adaptive optics…
