SAXO+, the second-stage adaptive optics for SPHERE: high contrast performance analysis

The SAXO+ system is a planned second-stage Adaptive Optics (AO) upgrade to the VLT/SPHERE eXtreme Adaptive Optics (SAXO) system. This consists of adding a second adaptive optics stage using a near-infrared pyramid wavefront sensor to record images of fainter exoplanets around redder stars. In this work, we compare the...

METIS high-contrast imaging simulations: from instrument modelling to science readiness

The Mid-infrared Extremely Large Telescope (ELT) Imager and Spectrograph (METIS) instrument, expected to see first light in early 2030, aims to detect and characterise exoplanets and circumstellar disks through high contrast imaging (HCI) and spectroscopy. The High-contrast End-to-End Performance Simulator (HEEPS), ini...
