Fainter and closer: finding planets by symmetry breaking
Erez N. Ribak, Szymon Gladysz
Imaging of planets is very difficult, due to the glare from their nearby, much brighter suns. Static and slowly-evolving aberrations are the limiting factors, even after applicatio…
Reference-less detection, astrometry, and photometry of faint companions with adaptive optics
Szymon Gladysz, Julian C. Christou
We propose a complete framework for the detection, astrometry, and photometry of faint companions from a sequence of adaptive optics corrected short exposures. The algorithms explo…
Temporal variability and statistics of the Strehl ratio in adaptive-optics images
Szymon Gladysz, Julian C. Christou, L. William Bradford +1
We have investigated the temporal variability and statistics of the "instantaneous" Strehl ratio. The observations were carried out with the 3.63-m AEOS telescope equipped with a h…
Detection of faint companions through stochastic speckle discrimination
Szymon Gladysz, Julian C. Christou
We propose a new post-processing technique for the detection of faint companions from a sequence of adaptive optics corrected short exposures. The algorithm exploits the difference…
