White dwarf encountering a sub-dwarf planet. It's a thermal event, not a nuclear one. Not an exploding star, not a pulsar. blackbody infers stellar temperatures. Lack of H-alpha would infer old progenitors (not small, hot new stars). Time frame could fit with a 10x Jupiter mass planet being accreted onto a white dwarf or neutron star. It's too bad it was so dim, they couldn't get any variability out of it (that would have been helpful). Also, x-ray and gamma ray data would have been good.
