Snooping around the Big Dog: VY CMa as Seen with Herschel/HIFI
Abstract
In the framework of the HIFISTARS guaranteed time key programme, we measured more than 70 molecular emission lines with high signal-to-noise ratio towards VY CMa using the high-resolution HIFI spectrometer (de Graauw et al. 2010) on board the Herschel1 satellite. The kinematic information obtained from the measured water lines supports the hypothesis of multiple outflow components. The observed strong maser lines give no indication for polarisation.
