Detection of sulfur in the galactic center
- 1. Center for Radiophysics and Space Research, Cornell University, Ithaca, NY
Description
A strong detection at the [S III] 19.71 μm line is reported for the galactic center region, Sgr A West. A line flux of 1.7 +- 0.2 x 10-17 W cm-2 is found for the 20 beam size measurement centered on IRS 1. A preliminary analysis indicates that the S III abundance relative to hydrogen is consistent with the cosmic abundance of sulfur, 1.6 x 10-5, if a filling factor of unity within the known clumps is assumed. However, the sulfur abundance in the galactic center may be as much as a factor of 3 overabundant if a filling factor of 0.03 is adoped, a value found to hold for some galactic H II regions
