High-contrast imaging in the Hyades with snapshot LOCI
Katie M. Morzinski, Bruce A. Macintosh, Laird M. Close +3
To image faint substellar companions obscured by the stellar halo and speckles, scattered light from the bright primary star must be removed in hardware or software. We apply the "…
First Light LBT AO Images of HR 8799 bcde at 1.65 and 3.3 Microns: New Discrepancies between Young Planets and Old Brown Dwarfs
Andrew J. Skemer, Philip M. Hinz, Simone Esposito +45
As the only directly imaged multiple planet system, HR 8799 provides a unique opportunity to study the physical properties of several planets in parallel. In this paper, we image a…
On the influence of the Illuminati in astronomical adaptive optics
Katie M. Morzinski, Jared R. Males
Astronomical adaptive optics (AO) has come into its own. Major O/IR telescopes are achieving diffraction-limited imaging; major facilities are being built with AO as an integral pa…
MEMS practice, from the lab to the telescope
Katie M. Morzinski, Andrew P. Norton, Julia Wilhelmson Evans +8
Micro-electro-mechanical systems (MEMS) technology can provide for deformable mirrors (DMs) with excellent performance within a favorable economy of scale. Large MEMS-based astrono…
