Structure

NGC 4570 has a nuclear disc that extends to a radius of about ~330  ly (100  pc ). In between [7] the nuclear disk and the surrounding two stellar rings and the outer disk, [8] [9] there is a gap that separates the outer edge of the nuclear disk and the inner edge of the main disk by about ~330  ly (100  pc ). [7] This multi-disc structure may have been shaped through secular evolution induced by a small nuclear bar. [10] [9] However, observations of the globular clusters surrounding NGC 4570 have found a significant population with ages ranging from about 1–3 billion years. Surprisingly, the estimated ages of the young globular clusters appears to be in good agreement with the estimated age of the stellar population of the nuclear disc (≤2 Gyr). This suggests that the young globular clusters and the nuclear disc instead formed from a merger or accretion event which involved significant amounts of gas and triggered a strong starburst in the galaxy. [11]

Globular Clusters

About 120 globular clusters have been detected surrounding NGC 4570. [8]
