DOI: 10.1016/j.ijleo.2021.167896
Abstract: Abstract In order to increase the swath and reduce the volume of hyperspectral remote sensing instruments, the compact, long-slit Wynne-Offner spectrometer is detailedly investigated. Through tracing the chief ray, expressions of astigmatism are deduced, and… read more here.

DOI: 10.1093/mnras/staa1444
Abstract: The determination of the fundamental properties (mass, separation, age, gravity and atmospheric properties) of brown dwarf companions allows us to infer crucial informations on their formation and evolution mechanisms. Spectroscopy of substellar companions is available… read more here.
