Los cuerpos rocosos supervivientes pueden romperse formando un disco alrededor de la estrella central muerta.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sin embargo, el disco alrededor de J1328-1450 es diferente de los observados alrededor de otras estrellas muertas: en lugar de tener s\u00f3lo un anillo de escombros planetarios vaporizados, la estrella est\u00e1 rodeada por dos anillos conc\u00e9ntricos de escombros.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cLa estructura que vemos en este sistema es particularmente intrigante porque los dos anillos gaseosos son notablemente estables y permanecen separados por una brecha\u201d, afirm\u00f3 el coautor Felipe Lagos-Vilches, astr\u00f3nomo de la Universidad de Warwick (Reino Unido), y de la Universidad T\u00e9cnica Federico Santa Mar\u00eda (Chile).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Gentile Fusillo, quien tambi\u00e9n est\u00e1 afiliado al INAF-Observatorio Astron\u00f3mico de Trieste, explic\u00f3 que \u201cver este sistema es como echar un vistazo al violento y ca\u00f3tico proceso por el cual un sistema planetario encuentra su final, y sugiere que las estrellas muertas pueden tener estructuras discales mucho m\u00e1s complejas de lo que se pensaba anteriormente\u201d.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Seg\u00fan el equipo, esta compleja doble estructura se mantiene gracias a dos cuerpos supervivientes similares a planetas, en \u00f3rbitas separadas. Estiman que el del anillo interior tiene el tama\u00f1o de un asteroide t\u00edpico, de unos pocos kil\u00f3metros de di\u00e1metro, mientras el exterior podr\u00eda ser tan grande como Plut\u00f3n, o incluso del tama\u00f1o de nuestra Luna.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Todos los discos de escombros conocidos alrededor de enanas blancas han sido identificados por la firma observacional, lo que indica la presencia de un \u00fanico disco plano y giratorio.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>El disco parece estar moldeado por dos cuerpos planetarios, uno posiblemente tan grande como Plut\u00f3n, que han sobrevivido a la violenta muerte de la estrella.
