HIFISTARS Overview HIFISTARS Primary Data Access

Overview

"HIFISTARS: The physical and chemical properties of circumstellar environments around evolved stars" 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. If you use HIFISTARS data, please cite Neufeld et al. (2011).
