Abstract

The Chandra X-ray Observatory carries two transmission gratings on-board, each of them optimized for high- and low-energy photons, respectively. Each grating can be put in the beam behind Chandra's High-Resolution Mirror Assembly (HRMA); the photons collected with the HRMA and dispersed by the gratings are then collected by one of two imaging detectors located at the focal of the telescope. The Low-Energy Transmission Grating Spectrometer, LETGS, is sensitive in the range ~2 - 170 Angstroms, and is a powerful tool to study hot plasmas in a variety of astrophysical environments, from stellar coronae to clusters of galaxies. Here we report on the status of this instrument, and we describe some of the scientific results obtained with it.
