Lyman Imaging Telescope Experiment

摘要

Abstract: We describe the Lyman Imaging Telescope Experiment (LITE) which is a NASA Ultraviolet Astrophysics Branch supported Advanced Mission Concept mission. The prime scientific aim of the LITE mission will be to carry out the first set of very high spatial resolution (0.2 arc sec), wide field of view (10 arc minute), pointed observations in several narrow wavelength bands in the far ultraviolet region of the spectrum (900 - 1600 angstroms). LITE will possess excellent detection sensitivity, such that limiting magnitudes for typical images are expected to be close to that of the HST WFPC II instrument. The proposed far ultraviolet astrophysical studies will encompass the emission of diffuse gas with temperatures in the range 80,000 - 1,000,000 K.!14
