Debris rings discovery around white dwarf J1328−1450
Overview
Astronomers using the European Southern Observatory’s Very Large Telescope have identified a rare debris structure around the white dwarf J1328−1450, located roughly 1,600 light-years from Earth. The system features two distinct, concentric rings of gas containing rocky elements like calcium, oxygen, magnesium, and iron, separated by a gap where gas is absent.
Research published in Nature Astronomy suggests these rings may originate from different regions of an ancient planetary system or different layers of a single disrupted body. The stability of the rings might be maintained by surviving planetary objects, with one body estimated to be similar to a small asteroid and a larger outer body comparable to the size of Pluto or the Moon. This discovery offers insights into the final evolutionary stages of solar systems and the fate of planetary remnants.
