NGC 1530 has a
″. It includes a clumpy, star-forming nuclear ring structure with a radius of 21″.[9] Star formation is particularly high in the nucleus region and at the ends of the bar, but weak in between these locations.[10] This activity appears to be taking place primarily on the trailing side of the bar where gas pressure is highest.[11] Two linear dust lanes are visible along the bar, which outline shock fronts in the flow of gas.[12]
Mass is flowing into the nuclear ring from the bar at the rate of one solar mass per year[13] with infall velocities of up to 100 km/s.[12] The central region has over 25% of the free gaseous hydrogen in the galaxy.[12] There was some suggestion that the galaxy has a second, inner bar, but this instead appears to be an inner spiral structure. This spiral has one arm brighter than the other, appearing lopsided.[14]
