We report the observation of the Intra-Cluster Medium ( ICM ) of Abell 85 by the X-ray satellite BeppoSAX .
We have both analysed the spectrum obtained in the central 8 arcmin circular region centred on the Very Steep Spectrum Radio Source ( VSSRS ) and the spectra from a number of sub-regions .
Analysis of the spectra allowed us to independently obtain new estimates of the temperature , metallicity and line-of-sight hydrogen density column , both globally ( T = 6.6 \pm 0.3 keV , Z = 0.38 \pm 0.06 Z _ { \odot } and N _ { H } = 5.5 ^ { +0.9 } _ { -0.7 } 10 ^ { 20 } cm ^ { -2 } ) and locally .
These measures are in good agreement with previous measures based on ROSAT and ASCA data .
In the region of the VSRSS , we have tried to disentangle the thermal from the non-thermal X-ray emission .
Although we could not do this unambiguously , we have nonetheless estimated the extended magnetic field using the radio spectrum available for this region .
We obtain a lower limit intensity of 0.9 \mu G , consistent with our previous estimate .
We also derive \alpha -elements/iron abundance ratios that turn out to be higher than 1 .
Such a result tends to support the burst model for elliptical galaxies , where a strong galactic wind develops early in the galaxy history and type II supernovae ( SN ) may have the main role in the enrichment of the ICM .
A two-temperature ICM model was fitted in the central region yielding a main component with roughly the mean cluster temperature and a cooler component with temperature less than 0.1 keV .
