Abstract

We present first on-sky performance results of KalAO, the natural guide star adaptive optics imager on the 1.2m Swiss telescope in La Silla, Chile. It is designed to reach at least 30% Strehl in order to detect stellar companions as close as the 150mas in visible-light, at diffraction limit. KalAO was built to search for binarity in planet hosting stars by following-up planet candidates primarily from the TESS satellite survey. The optical design is optimised for the 450-900 nm wavelength range and is fitted with SDSS griz filters. Wavefront control works down to I-magnitude 10 stars in order to probe the same parameter space as radial velocity instruments such as HARPS and NIRPS. The system first closed the loop on sky in November 2023 and reached diffraction limit imaging in February 2024. It can carry out AO corrected observation of up to 500 targets in one night, with a Strehl ratio of ≈ 30%.
