Alternative approach to precision narrow-angle astrometry for Antarctic long baseline interferometry
Y. Kok, M. J. Ireland, A. C. Rizzuto +4
The conventional approach to high-precision narrow-angle astrometry using a long baseline interferometer is to directly measure the fringe packet separation of a target and a nearb…
The Science Case for the Planet Formation Imager (PFI)
Stefan Kraus, John Monnier, Tim Harries +16
Among the most fascinating and hotly-debated areas in contemporary astrophysics are the means by which planetary systems are assembled from the large rotating disks of gas and dust…
Planet Formation Imager (PFI): Introduction and Technical Considerations
John D. Monnier, Stefan Kraus, David Buscher +13
Complex non-linear and dynamic processes lie at the heart of the planet formation process. Through numerical simulation and basic observational constraints, the basics of planet fo…
Gemini Planet imager Observational Calibrations X: Non-Redundant Masking on GPI
Alexandra Z. Greenbaum, Anthony Cheetham, Anand Sivaramakrishnan +18
The Gemini Planet Imager (GPI) Extreme Adaptive Optics Coronograph contains an interferometric mode: a 10-hole non-redundant mask (NRM) in its pupil wheel. GPI operates at $Y, J, H…
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…
A Demonstration of Wavefront Sensing and Mirror Phasing from the Image Domain
Benjamin Pope, Nick Cvetojevic, Anthony Cheetham +3
In astronomy and microscopy, distortions in the wavefront affect the dynamic range of a high contrast imaging system. These aberrations are either imposed by a turbulent medium suc…
