Demonstration of broadband contrast at 1.2 /D and greater for the EXCEDE Starlight Suppression System
Dan Sirbu, Sandrine J. Thomas, Ruslan Belikov +8
The EXoplanetary Circumstellar Environments and Disk Explorer (EXCEDE) science mission concept uses a visible-wavelength Phase-Induced Amplitude Apodization (PIAA) coronagraph to e…
Wavefront retrieval through random pupil plane phase probes: Gerchberg-Saxton approach
Eugene Pluzhnik, Dan Sirbu, Ruslan Belikov +2
A pupil plane wavefront reconstruction procedure is proposed based on analysis of a sequence of focal plane images corresponding to a sequence of random pupil plane phase probes. T…
Prospects for exoplanet imaging in multi-star systems with starshades
Dan Sirbu, Ruslan Belikov, Eduardo Bendek +3
We explore the capabilities of a starshade mission to directly image multi-star systems. In addition to the diffracted and scattered light for the on-axis star, a multi-star system…
Searching for Faint Comoving Companions to the Centauri system in the VVV Survey Infrared Images
J. C. Beamin, D. Minniti, J. B. Pullen +7
The VVV survey has observed the southern disk of the Milky Way in the near infrared, covering 240 deg in the filters. We search the VVV Survey images in a 19…
Individual, Model-Independent Masses of the Closest Known Brown Dwarf Binary to the Sun
E. Victor Garcia, S. Mark Ammons, Maissa Salama +18
At a distance of 2~pc, our nearest brown dwarf neighbor, Luhman 16 AB, has been extensively studied since its discovery 3 years ago, yet its most fundamental parameter -- the masse…
Techniques for High-Contrast Imaging in Multi-Star Systems II: Multi-Star Wavefront Control
Dan Sirbu, Sandrine Thomas, Ruslan Belikov +1
Direct imaging of exoplanets represents a challenge for astronomical instrumentation due to the high-contrast ratio and small angular separation between the host star and the faint…
Development of a Miniaturized Deformable Mirror Controller
Eduardo Bendek, Dana Lynch, Eugene Pluzhnik +4
High-Performance Adaptive Optics systems are rapidly spreading as useful applications in the fields of astronomy, ophthalmology, and telecommunications. This technology is critical…
