Snooping around the big dog: VY CMa as seen with Herschel/HIFI
E. De Beck, L. Decin, K. M. Menten, A. Marston, D. Teyssier, and the, HIFISTARS team

TL;DR
This study used Herschel/HIFI to observe over 70 molecular emission lines in VY CMa, revealing multiple outflow components and providing detailed kinematic data, with no significant polarization in maser lines.
Contribution
First high-resolution spectral survey of VY CMa with Herschel/HIFI revealing complex outflow structures and molecular emission characteristics.
Findings
Multiple outflow components supported by water line kinematics
High-intensity maser lines show no strong polarization
Over 70 molecular emission lines detected with high S/N
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 on board the Herschel satellite. The kinematic information obtained from the measured water lines supports the hypothesis of multiple outflow components. The observed high-intensity maser lines give no indication for strong polarisation.
