Non-recovery of the faint nIR spectra from Brown Dwarf companions around FGK stars.

Abstract
High resolution NIR spectrographs have played an important role in the detection and characterization of exoplanet atmospheres. Throughout my PhD I have tried two techniques to extract the faint blended spectra of Brown Dwarf companions in CRIRES data. I will present the two techniques attempted, direct subtraction and chi squared synthethic recovery, discuss some of their limitiations and highlight the main reasons for the unsuccessful detections.
