Description
HARPS3 is a high resolution (R~115,000) stabilized Doppler spectrograph covering a wavelength range from 380-690nm with polarimetric capabilities that is coming online on the roboticized 2.5m Isaac Newton Telescope (INT) at La Palma in Fall 2025. HARPS3 is designed to enable ~10cm/s radial velocity (RV) precision on nearby bright solar-type stars to enable the detection of Earth Twins. The Netherlands is a major partner in the instrument having contributed key hardware as well as being a partner of the INT. A component of the time on the telescope (~50%) will be used to carry out the Terra Hunting Experiment (THE), a 10-year survey to probe for Earth-twins around nearby bright solar-type stars. Additionally, about ~1h of Open Time will be available for the Dutch Community per night. In this talk, we will discuss HARPS3, its capabilities, and results from a Community Discussion Day held in March 2025 to discuss possible science cases for the Dutch Open Time.
