Description
Technology now exists to enable large optical systems that are capable of resolving and measuring faint sources not accessible with current remote sensing instruments and detectors. The possibility of creating ground-based telescopes at the 50m-scale with sufficient wavefront control to both fully overcome the effects of the atmosphere, but with exquisite coronagraphic capability starting at the telescope entrance pupil, means we may solve some of the most fundamental cross-cutting scientific questions: like, "is there life outside of the solar system?".The IAC is part of a consortium with the University of Hawaii and Universities in Lyon to develop the technologies needed for the next generation telescopes aimed at direct imaging of exoplanets around bright stars: the "ExoLife Finder (ELF)" telescope.We have a detailed design for a 3.5-m diameter prototype, nicknamed Small-ELF, tobe built and installed at Teide Observatory by 2025. I will present the technologicaland scientific challenges of such telescope.

    Observational evidence of different formation mechanisms of Solar System-type architectures across spectral types

    Despite being the most abundant classes of known exoplanets, super-Earths and mini-Neptunes are absent in our Solar System, and the exact reason for this is still unknown. Some models suggest that cold-Jupiters play a major role in the formation of inner low-mass planets. This could explain the current architecture of our Solar System, and the

    First light and results for atmospheric characterization with The Near Infra-Red Planet Searcher (NIRPS)

    NIRPS is a new fiber-fed high spectral resolution (~80k) spectrograph assisted by adaptive optics installed on the 3.6m telescope of ESO at LaSilla, Chile. Operated simultaneously with HARPS, NIRPS covers the Y, J, and H bands. The commissioning phase demonstrated high stability for time-series observations along precise radial velocities reaching

    3.5 years of observing exoplanet day sides with CHEOPS

    Characterising Exoplanets Satellite (CHEOPS) is the first ESA exoplanet space mission. The satellite carries a 30cm telescope, optimised to deliver exquisite (ppm-level) photometry of bright exoplanetary systems at optical wavelengths. CHEOPS has spent approximately 20% of its observing time during its 3.5-year long nominal mission studying
