A parameter scan of dark zone maintenance for high-contrast imaging of exoplanets using theoretical and experimental implementations
Saikrishna Manojkumar, Christine L. Page, Leonid Pogorelyuk +14
Maintaining wavefront stability while directly imaging exoplanets over long exposure times is an ongoing problem in the field of high-contrast imaging. Robust and efficient high-or…
STARI: STarlight Acquisition and Reflection toward Interferometry
John D. Monnier, Prachet Jain, Shashank Kalluri +7
We present the concept for STARI: STarlight Acquisition and Reflection toward Interferometry. If launched, STARI will be the first mission to control a 3-D CubeSat formation to the…
Optical modeling for the evaluation of HOWFSC on embedded processors
Kian Milani, Ewan Douglas, Leonid Pogorelyuk +5
The correction of quasi-static wavefront errors within a coronagraphic optical system will be a key challenge to overcome in order to directly image exoplanets in reflected light.…
Coronagraphic Data Post-processing Using Projections on Instrumental Modes
Yinzi Xin, Laurent Pueyo, Romain Laugier +4
Directly observing exoplanets with coronagraphs is impeded by the presence of speckles from aberrations in the optical path, which can be mitigated in hardware with wavefront contr…
Using Ground-Based Telescopes to Mature Key Technologies and Advance Science for Future NASA Exoplanet Direct Imaging Missions
Thayne Currie, Ruslan Belikov, Olivier Guyon +8
Ground-based telescopes have been playing a leading role in exoplanet direct imaging science and technological development for the past two decades and will continue to have an ind…
