The design of a near-IR spectrometer for the Gemini 8m telescopes is described. This instrument, GNIRS, provides coverage from 0.9 to 5.5 micrometers at several spectral resolutions and two pixel scales. Capabilities include an imaging mode intended

The spectra of both close companion stars to SN 1987A in the LMC have been classified as type B2 from blue-violet digital data; the H-gamma equivalent width of Star 2 and the absolute visual magnitude of both stars correspond to giant luminosity clas

A review of the available spectral geometric albedo measurements for Mars was presented earlier for the spectral region 0.3 to 1.1μ. A new observational study has greatly increased the store of data, especially for small Martian regions and for the
