We have compiled a database of all stellar observations made with Chandra's High Energy Transmission Grating (HETG) to facilitate the rapid comparison, characterization, and analysis of high-resolution stellar X-ray spectra. This database, known as X-Atlas, is accessible through a web interface with extensive searching and interactive plotting capabilities. For each target, X-Atlas also features predictions of the low-resolution ACIS spectra convolved from the HETG data for comparison with stellar sources in archival ACIS images. X-Atlas offers more than 130 observations of over 65 stars and will be updated as additional observations become public. The atlas is currently expanding to non-stellar point sources and eventually will include Low Energy Transmission Grating data as well.
