| dbo:abstract | كيبلر 70 سي (بالإنجليزية: Kepler-70c) الذي يرمز له بالرمز Kepler-70c، هو كوكب خارج المجموعة الشمسية، في كوكبة الدجاجة (كوكبة)، يتبع Kepler-70. (ar) Kepler-70c (formerly called KOI-55.02; sometimes listed as KOI-55 c) is one of two postulated exoplanets orbiting the sdB star Kepler-70. Their discovery was announced in 2011. However, later research suggests that the two exoplanets probably do not exist, and that "pulsation modes visible beyond the cut-off frequency of the star" were a more likely explanation for the signals believed to indicate exoplanets. This is not proven with certainty one way or the other. If it exists, Kepler-70c orbits its host along with another planet, Kepler-70b. Both of these planets orbit very close to their host star. Kepler-70c completes one orbit around its star in just 8.232 hours. It is also one of the hottest exoplanets as of mid-2013. It has a high density, suggesting that it is largely composed of metals. Kepler-70b passes 240,000 km away from Kepler-70c during their closest approach. This is currently the closest recorded approach between planets. Such orbital configuration is relatively stable due to orbital resonance between planets and small Hill spheres of planets due to proximity of the star. According to the main author of the paper in Nature which announced the discovery of the two planets, Stephane Charpinet, the two planets "probably plunged deep into the star's envelope during the red giant phase, but survived." However, this is not the first sighting of planets orbiting a post-red giant star - numerous pulsar planets have been observed, including one that orbits closer to its host star, and consequently in a shorter time than, any other planet. (en) Kepler-70c (antiguamente llamado KOI-55.02; a veces catalogado como KOI-55 c) es un planeta descubierto orbitando la Estrella subenana de tipo B (sdB) . Orbita a su estrella otro planeta, Kepler-70b, ambas orbitan muy cerca de su estrella madre. Kepler-70b completa una órbita alrededor de su estrella en sólo 8,232 horas. También es uno de los exoplanetas más calientes hasta mediados de 2013. Tiene una alta densidad, lo que sugiere que se compone en gran parte de los metales. Kepler-70b pasa a 240.000 kilómetros de distancia de Kepler-70c durante su máximo acercamiento. Este es actualmente el máximo acercamiento registrado entre planetas. Según el autor principal del artículo en Nature , que anunció el descubrimiento de los dos planetas, Stephane Charpinet, los dos planetas "probablemente se hundieron profundamente en halo de la estrella durante la fase de gigante roja, pero sobrevivieron". Sin embargo, este no es el primer avistamiento de planetas que orbitan alrededor de una estrella post-gigante roja. Se han observado numerosos planetas en púlsares, pero ningún planeta se ha encontrado con un período tan corto alrededor de ninguna estrella, sea o no en la secuencia principal. (es) Kepler-70c (anteriormente denominado KOI-55.02; por vezes listado como KOI-55 c) é um planeta descoberto a orbitar a estrela subanã B (sdB) Kepler-70. Orbita a sua hospedeira juntamente com outro planeta, Kepler-70b, ambos os quais orbitam muito próximo da sua estrela hospedeira. Kepler-70c completa uma órbita em torno da sua estrela em apenas 8,232 horas. Também é um dos exoplanetas mais quentes até meados de 2013. Tem uma alta densidade, o que sugere que é composto em grande parte de metais. (pt) |
