As white dwarfs chew up their planets, sometimes we catch a WD1145 + 017 at supper. Now G238-44, 86 lightyears out.
This one is consuming not just rock but also ice.
The rock, they say, looks more like iron. The planet was once like Mercury - alternatively, the mantle has been blasted or consumed already, and the star is now getting to the core. I don't know if there has been a proper analysis of the dwarf's composition.
The ice is nitrogen so seems Kuiperish. I don't think nitrogen is much created in the death of A-class stars.
