摘要
We use Ha and R-band images of a sample of ring galaxies to identify systems with stellar disks outside the star-forming rings. Such systems are expected under the collisional scenario of ring formation (Lynds & Toomre 1976), but haven't been conclusively detected. We here report the detection of stellar disks outside the ring, as traced by Ha, in Arp 141, Arp 143 and NGC 2793.
