In the last two decades High Resolution (HR) Spectroscopy has been a rapidly growing field both from the scientific and technological points of view.  HR spectroscopy in the optical bands is now a mature field of research that produced outstanding results in many research fields, such as the detection of exoplanets and the study of stellar chemical abundances. Much fewer results were so far achieved in the near infrared (NIR) bands because of the great technical difficulties to build suitable instruments. Nonetheless, NIR is a crucial spectral range to explore, offering new challenges in the search and characterization of exoplanets, chemical abundances of cool stars and reddened objects. 

The detection and characterization of exoplanets is one the key science cases of modern astrophysics. In particular, the study of planets around M-type stars - the most numerous stars in the Galaxy - and the characterization of the atmosphere of transiting planet using molecular features (e.g. water, methane, carbon dioxide and oxygen) can only be achieved via NIR HR Spectroscopy.

At the same time, several stellar processes as mass loss, winds, magnetic fields and chemical enrichment are still not well known. The NIR spectral range allows us to investigate several types of objects, as young and reddened stars as well as old and evolved stars from the very inner Galaxy out to the Local Group.

The pioneering survey of APOGEE is generating the first systematic database of stellar spectra at moderate resolving power and over a limited range of wavelengths. Only a handful of NIR spectrographs with higher resolving power and broad spectral coverage (CARMENES, IGRINS, GIANO/GIARPS) are presently working, while a few others (e.g. CRIRES+, SPIROU and NIRPS) are expected to come in the near future.

Within this framework it is now important to review our achievements and collect information on the state of the on-going scientific and technological projects.

This EWASS Special Session is intended to gather experts in the NIR HR Spectroscopy on various topics and instruments, giving an opportunity to discuss and create new collaborations between the groups. The ultimate goal is achieving as soon as possible a level of expertise comparable to that since long available in optical HR spectroscopy. This is a mandatory pathway in preparation to the exploitation of the HR spectroscopy in the forthcoming ELTs era.
