Focal Plane Wavefront Sensing on SUBARU/SCExAO
Sebastien Vievard, Steven P. Bos, Frederic Cassaing +20
Focal plane wavefront sensing is an elegant solution for wavefront sensing since near-focal images of any source taken by a detector show distortions in the presence of aberrations…
Calibration of the instrumental polarization effects of SCExAO-CHARIS' spectropolarimetric mode
Rob G. van Holstein, Steven P. Bos, Jasper Ruigrok +18
SCExAO at the Subaru telescope is a visible and near-infrared high-contrast imaging instrument employing extreme adaptive optics and coronagraphy. The instrument feeds the near-inf…
Laboratory Demonstration of Spatial Linear Dark Field Control For Imaging Extrasolar Planets in Reflected Light
Thayne Currie, Eugene Pluzhnik, Olivier Guyon +15
Imaging planets in reflected light, a key focus of future NASA missions and ELTs, requires advanced wavefront control to maintain a deep, temporally correlated null of stellar halo…
Detection of polarization neutral points in observations of the combined corona and sky during the 21 August 2017 total solar eclipse
Frans Snik, Steven P. Bos, Stefanie A. Brackenhoff +7
We report the results of polarimetric observations of the total solar eclipse of 21 August 2017 from Rexburg, Idaho (USA). We use three synchronized DSLR cameras with polarization…
On-sky verification of Fast and Furious focal-plane wavefront sensing: Moving forward toward controlling the island effect at Subaru/SCExAO
Steven P. Bos, Sébastien Vievard, Michael J. Wilby +8
High-contrast imaging (HCI) observations of exoplanets can be limited by the island effect (IE). On the current generation of telescopes, the IE becomes a severe problem when the g…
Vector speckle grid: instantaneous incoherent speckle grid for high-precision astrometry and photometry in high-contrast imaging
Steven P. Bos
Photometric and astrometric monitoring of directly imaged exoplanets will deliver unique insights into their rotational periods, the distribution of cloud structures, weather, and…
