Descripción
The High Optical Resolution Spectrograph (HORus) has been available on the 10-m GTC telescope since early 2019. Based largely on optical elements reused from UES, in operation on the 4-m WHT in the 90s, HORuS provides a resolving power of 25,000 with nearly complete coverage in the range 380-700 nm. This instrument gives a signal-to-noise ratio at 550 nm of 75 for a V=15 solar-like star in 1 hour, and its particularly well-suited for stellar spectroscopy and exoplanet transits. This seminar will describe the status of the instrument, offer tips to prepare observations and analyze them with its dedicated data reduction package, and touch on future plans.
