irsasupport@ipac.caltech.edu "HIFISTARS: The physical and chemical properties of circumstellar environments around evolved starsquot; is a Herschel Guaranteed Time Key Program (KPGT_vbujarra_1). HIFISTARS is devoted to the study of the warm gas and water vapor content of the molecular envelopes around evolved stars: AGB stars, red super- and hyper-giants (RSGs and RHGs); and their descendants, the pre-planetary nebulae (pPNe), planetary nebulae (PNe), and yellow hyper-giants (YHGs). This study has been done by means of the observation of rotational lines of several molecules sensitive to different properties and excitation conditions of these circumstellar envelopes. https://irsa.ipac.caltech.edu/data/Herschel/HIFISTARS/overview.html Survey Research 1 https://irsa.ipac.caltech.edu/SSA?COLLECTION=herschel_hifistars& minimal survey archival ICRS 191.282625 45.44025 0.5 Millimeter
