TITLE:

SIMUTOOLS: A specter simulation tool for NIRPS

KEY WORDS:

SUMMARY:

With the possibility of using the variation in radial velocity to find exoplanets, that has begun with the discovery of 51 Pegasi b, the exoplanet scene has been a target of great interest. From this pioneer discovery up to now, various spectrometers were and have been built with the purpose of searching for exoplanets. In this context, NIRPS (Near Infra-Red Planet Searcher) is included, a spectrometer which will be mounted jointly to HARPS (High Accuracy Radial velocity Planet Searcher), in Chile, and will operate in the near infrared range, with the goal of searching for explanets orbiting low mass stars. In this work, we present a program developed for NIRPS, SIMUTOOLS, which will simulate the specter that reachs the detector (H4RG). These simulations expect to: anticipate any particularity that may happen to the instrument, or the detector, so that it may be corrected beforehand, prior to NIRPS’ functioning; and also test and calibrate the data reduction software (DRS). This code was successful in its simulations, presenting the particularities of each type of observation, showing intrinsic
effects due to the instrument, the difference between high accuracy and high efficiency modes and, lastly, the simulation of specters from different M stars, in which we may also realize the influence from atmospheric absorption in the observation.
