MESS Herschel Data
You can get a close-up map of a region by clicking on any area in red on the above image, or by typing a coordinate below.
Herschel data from the "Mass-loss of Evolved StarS" (MESS) Guaranteed-Time Key Program are available here. IRSA is serving the MESS PACS imaging of 108 evolved stars. This is Herschel program KPGT_mgroen01_1.
The sample of AGB stars has been selected to cover all chemical types (M-, S-, C-stars), variability types (irregular, semi-regular, Miras) and periods, and mass-loss rates. Stars have been selected to have high IRAS fluxes and low background levels.
There are several search options:
  • Use the form below to enter a coordinate or object name.
  • Click within a red region of the image above.
  • Browse the MESS target list.
  • Download all of the MESS data (6.5 GB).
The canonical paper for MESS is Groenewegen et al. (2011).
