This gaseous ring consists of refractory elements - substances that remain solid at high temperatures - such as iron, magnesium, silicon, and calcium. The presence of this material so close to the star suggests a secondary origin, likely resulting from the ongoing collisions of rocky bodies orbiting the star. This system is a rare ...
