Outer Rings in Early-Type Disk Galaxies: Star Formation Rate
The total ring star formation rates and their surface densities are determined for 34 early-type disk galaxies with outer stellar rings which were detected in the UV with the GALEX space telescope. The total level of the integrated star formation rate in the outer rings appears to be low – less than...

| description | The total ring star formation rates and their surface densities are determined for 34 early-type disk galaxies with outer stellar rings which were detected in the UV with the GALEX space telescope. The total level of the integrated star formation rate in the outer rings appears to be low – less than 0.1 M⊙ yr−1, with typical surface densities from 10−4 to 10−3M⊙ yr−1 kpc−2. |
