The Subaru Coronagraphic Extreme Adaptive Optics system: enabling high-contrast imaging on solar-system scales
N. Jovanovic, F. Martinache, O. Guyon +35
The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument is a multipurpose high-contrast imaging platform designed for the discovery and detailed characterization of ex…
High Angular Resolution Stellar Imaging with Occultations from the Cassini Spacecraft II: Kronocyclic Tomography
Paul N. Stewart, Peter G. Tuthill, Philip D. Nicholson +2
We present an advance in the use of Cassini observations of stellar occultations by the rings of Saturn for stellar studies. Stewart et al. (2013) demonstrated the potential use of…
High-performance 3D waveguide architecture for astronomical pupil-remapping interferometry
Barnaby Norris, Nick Cvetojevic, Simon Gross +6
The detection and characterisation of extra-solar planets is a major theme driving modern astronomy, with the vast majority of such measurements being achieved by Doppler radial-ve…
The VAMPIRES instrument: Imaging the innermost regions of protoplanetary disks with polarimetric interferometry
Barnaby Norris, Peter Tuthill, Nemanja Jovanovic +4
Direct imaging of protoplanetary disks promises to provide key insight into the complex sequence of processes by which planets are formed. However imaging the innermost region of s…
SCExAO as a precursor to an ELT exoplanet direct imaging instrument
Nemanja Jovanovic, Olivier Guyon, Frantz martinache +11
The Subaru Coronagraphic Extreme AO (SCExAO) instrument consists of a high performance Phase Induced Amplitude Apodisation (PIAA) coronagraph combined with an extreme Adaptive Opti…
High Angular Resolution Stellar Imaging with Occultations from the Cassini Spacecraft I: Observational Technique
Paul N. Stewart, Peter G. Tuthill, Matthew M. Hedman +2
We present novel observations utilising the Cassini spacecraft to conduct an observing campaign for stellar astronomy from a vantage point in the outer solar system. By exploiting…
Starlight Demonstration of the Dragonfly Instrument: an Integrated Photonic Pupil Remapping Interferometer for High Contrast Imaging
N. Jovanovic, P. G. Tuthill, B. Norris +13
In the two decades since the first extra-solar planet was discovered, the detection and characterization of extra-solar planets has become one of the key endeavors in all of modern…
Design of Optically Path Length Matched, Three-Dimensional Photonic Circuits Comprising Uniquely Routed Waveguides
Ned Charles, Nemanja Jovanovic, Simon Gross +6
A method for designing physically path length matched, three-dimensional photonic circuits is described. We focus specifically on the case where all the waveguides are uniquely rou…
Photonic Technologies for a Pupil Remapping Interferometer
Peter Tuthill, Nemanja Jovanovic, Sylvestre Lacour +9
Interest in pupil-remapping interferometry, in which a single telescope pupil is fragmented and recombined using fiber optic technologies, has been growing among a number of groups…
Sparse Aperture Masking (SAM) at NAOS/CONICA on the VLT
Peter Tuthill, Sylvestre Lacour, Paola Amico +8
The new operational mode of aperture masking interferometry has been added to the CONICA camera which lies downstream of the Adaptive Optics (AO) corrected focus provided by NAOS o…
