Star Talk: Planets Around Expired Stars

star_talk_sep “Planets Around Expired Stars”, presented by Professor Yanqin Wu

Abstract: Professor Yanqin Wu investigates the formation and evolution of planets, both inside and outside our own Solar System. Her current attention is devoted to a recently discovered puzzle, the presence of planetary systems around white dwarf stars, stars that have lived through their lives and are cooling off quietly in their cemeteries. The observational evidences are difficult to square with our current knowledge about the extra-solar planetary systems, and perhaps a new picture is required.

ngc7129

Our Sun is most likely formed some five billion years ago in a similar stellar nursery such as NGC7129, located some 3000 light-years away toward the constellation Cepheus. Noticeable in the image are the lovely bluish clouds that reflect the youthful starlight. The compact, deep red crescent shapes mark energetic, young stellar objects. Known as the Herbig-Haro objects, the shape and color of these objects are the characteristic of glowing hydrogen gas streaming away from newborn stars. The paler, reddish filaments are caused by the process of photoluminescence, where dust grains convert invisible ultraviolet starlight to visible red light.

This view of the night side of Pluto was captured by New Horizons last July when the spacecraft was 21000 kilometres from the planet (or 19 minutes after its closest approach). The photo also reveals the complex layers of the Plutonian’s hazy atmosphere. The landscape seen in the crescent view includes the southern areas of the nitrogen ice plains known as Sputnik Planum and the Norgay Montes.

Two bright galaxies can be observed in this sharp telescopic field of view; barred spiral galaxy, NGC 5101 (top right), and the edge-on galaxy, NGC 5708 (bottom left). The two galaxies are separated by about 0.5 degrees (or the full width of the moon). Found within the constellation Hydra, both galaxies are estimated to be around 90 million light-years away and similar in size to that of our own galaxy.
