EUV Observations of the Local Interstellar Medium with CHIPS
Abstract
The Cosmic Hot Interstellar Plasma Spectrometer (CHIPS) has been on orbit for almost 16 months, making spectral measurements of diffuse radiation in the EUV wavelength range 90 - 260 A. We report on the latest measurements and analysis of line radiation in this range, which thus far argue for less hot gas and a lower temperature in the local ISM than has been inferred from previous observations. We have also recently made the first high spectral resolution measurements of two comets (NEAT-Q4 and LINEAR-T7) in the EUV and report preliminary analysis of these spectra.
The CHIPS mission has been funded by NASA.- Publication:
