  <dc:description>The Near-InfraRed Planet Searcher (NIRPS) is designed to be an
ultra-stable infrared spectrograph to be installed on ESO’s 3.6 m Telescope
in La Silla, Chile. NIRPS is an adaptive optics (AO) fiber-fed spectrograph
operating from 0.98 to 1.8 μm and will be operated simultaneously with the
optical high-resolution spectrograph HARPS. NIRPS can operate in two modes
fed by two different fiber links permanently mounted at the Cassegrain focus
that use either 0.4 arcsecond-fibers for the High Accuracy Mode (HAM) or 0.9
arcsecond-fibers for the High Efficiency Mode (HEM). The wavelength range of
NIRPS is optimal for low-mass M dwarfs and the simultaneous NIRPS and HARPS
observations will improve stellar activity filtering methods given their
different wavelength coverages. The NIRPS front-end and AO system were
already tested on-sky at La Silla. The spectrograph and back-end is to be
shipped to La Silla and installed by end of 2021. Already we have adapted the
state-of-the-art ESPRESSO data reduction pipeline for NIRPS, obtained
accurate wavelength solutions with a Uranium Neon lamp, and obtained drift
stability results below 50 cm/s with a Fabry–Pérot etalon. We discuss the
current and expected instrument performance and the expected science results
of NIRPS.</dc:description>
