white dwarfs. Several planet candidates have recently been identified orbiting white dwarfs1, Mark S.,且有效温度(390412 K)远超预期的行星平衡温度(160 K), consistent with post-main-sequence tidal evolution to the present-day 0.02-au circular orbit. Our results provide a window into the ultimate fate of giant planets orbiting stars with masses similar to our Sun.
