Reportar ArchivoDescripción | Esto no tiene nada que ver con el curso, solo les mando el paper relativo al nuevo planeta tipo tierra descubiero recientemente. Esta es realmente una novedad y está recien salida del horno estelar. This Letter reports on the detection of two super-Earth planets in the Gl 581 system, already known to harbour a hot Neptune. One of the planets has a mass of 5M and resides in the habitable zone of the star. It is thus the known exoplanet which most resembles our own Earth. The other planet has a 7.7M mass and orbits at 0.25AU from the star. These two new light planets around an M3 dwarf further confirm the formerly tentative statistical trend for i) many more very low-mass planets being found around M dwarfs than around solar-type stars and ii) low-mass planets outnumbering Jovian planets around M dwarfs. |
