Context: The conventional approach to direct imaging has been the use of a single aperture coronagraph with wavefront correction via extreme adaptive optics. Such systems are limited to observing beyond an inner working (IWA) of a few $\mathit\lambda

Statistical tests with multi-wavelength Kernel-phase analysis for the detection and characterization of planetary companions

Autor: N'Diaye, Mamadou, Mary, David, Martinache, Frantz, Ligi, Roxanne, Cvetojevic, Nick, Chingaipe, Peter, Laugier, Romain

Kernel phase is a method to interpret stellar point source images by considering their formation as the analytical result of an interferometric process. Using Fourier formalism, this method allows for observing planetary companions around nearby star

3-beam self-calibrated Kernel nulling photonic interferometer

Autor: Cvetojevic, Nick, Martinache, Frantz, Chingaipe, Peter, Laugier, Romain, Ławniczuk, Katarzyna, Broeke, Ronald G., Ligi, Roxanne, N'Diaye, Mamadou, Mary, David

The use of interferometric nulling for the direct characterization of extrasolar planets is an exciting prospect, but one that faces many practical challenges when deployed on telescopes. The largest limitation is the extreme sensitivity of nullers t
