The birth of stars and planetary systems:[3] Near-infrared high-contrast slit spectroscopy at spectral resolution ranging from 100 to several thousands in order to gain a more complete view of the formation and evolution of the stars and their planetary systems. Planetary systems and the origin of life:[3] In order to observe various components of the Solar System (from planets and satellites to comets and Kuiper belt objects as well as of extra-solar planetary systems, high-contrast and spatially resolved NIRS at medium to high spectral resolution while maintaining high relative spectro-photometric stability is required.
