An all-sky catalog of solar-type dwarfs for exoplanetary transit surveys
V. Nascimbeni, G. Piotto, S. Ortolani +12
Most future surveys designed to discover transiting exoplanets, including TESS and PLATO, will target bright (V<13) and nearby solar-type stars having a spectral type later than F5…
High order dark wavefront sensing simulations
Roberto Ragazzoni, Carmelo Arcidiacono, Jacopo Farinato +8
Dark wavefront sensing takes shape following quantum mechanics concepts in which one is able to "see" an object in one path of a two-arm interferometer using an as low as desired a…
Dark tip-tilt sensing
Carmelo Arcidiacono, Roberto Ragazzoni, Valentina Viotto +6
Dark wavefront sensing in its simplest and more crude form is a quad-cell with a round spot of dark ink acting as occulting disk at the center. This sensor exhibits fainter limitin…
