Abstract
We are building a catalogue of fully-reprocessed observations of all evolved stars observed with Herschel (THROES) . In a first stage, we focus on observations performed with the PACS instrument in its full range spectroscopy mode. Once finished, the catalogue will offer all reduced data for each observation, as well as, complementary information from other observatories. As a first step, we concentrate our efforts on two main activities: 1) the reprocessing and data-reduction of more than 200 individual sources, observed by Herschel/PACS in the 55–210 micron range, available in the Herschel Science Archive (HSA); 2) The creation of an initial catalogue, accesible via web and the Virtual Observatory (VO), with all the information relative to PACS observations and the classification of the sources. Our ultimate goal will be to carry out a comprehensive and systematic study of the far infrared properties of low-and intermediate-mass (1–8 FX1) evolved stars using these data. These objects cover the whole range of possible evolutionary stages in this short-lived phase of stellar evolution, from AGB phase to the PN stage, displaying a wide variety of chemical and physical properties.
