MICADO spectroscopic mode for exoplanet characterization
Abstract
MICADO is a general-purpose near-infrared spectro-imager that will, among others, observe exoplanets, aiming to understand their physics, formation, and evolution. This instrument will follow up the current discoveries to allow an unprecedented characterization of architecture, orbits, circumplanetary disks and moons formation, detection of molecules, and atmospheric studies. This will become feasible by using the gain in angular resolution to resolve chemical species in the atmospheres of young Jupiter-like exoplanets and even more mature planets. The ELT will be a highly oversubscribed instrument, which makes it evident that synergies with current and future facilities will be fundamental. Only the best-suited, well-justified, game-changer targets will be observed. During the first stage of this ongoing project, we constrain that the main limitations for performing exoplanet-related science will arise from the host star speckles field contamination. We aim to characterize the speckle noise for the long-slit spectroscopic mode in contrast, projected separation, and wavelength dependency, among others. In this context, we are developing a data reduction and analysis strategy, which we present here.
