Planets with 2 suns.

According to a note appeared in the last number of The Astrophysical Journal, the Multiband Imaging Photometer for Spitzer on board of Spitzer Space Telescopes of NASA, showed that mature planetary (condition from birth of binary systems) systems, surrounded by disks of stellar powder (generated by collisions in planetesimals belts : asteroids, comets and possibly planets), would be but frequent around I) DOBLE SUN SYSTEMS, CLOSELY UNITED (0-3, Astronomical Units .UA-. 1 UA = Distance from the Earth to Sun) that those surrounding systems of a single sun. In these cases, the suns would move quickly one on the other due to the force of the gravity. Although according to David Trilling, the gravitational forces in these systems struggle to expel any planetesimal to the space, it is known that dozens of planets exist orbiting around a sun, of these duets. In these cases the settings of sun would be similar to those observed in our planet except that the second sun sighted as a brilliant star in the night, what has impelled someone to sustain that our solar system has also 2 suns. Theoretically, it would also exist the possibility to observe 2 suns setting in the horizon one after the other one.
In general, the binary systems would be 2 times but frequent that those constituted by an unique sun. Spitzer doesn't see directly to the planets, it deduces them for the form of the powder disk generated by asteroids and comets. Spitzer found but powder disks around binary closely united systems are more frecuent than those constituted by a single sun, what means that planets prefer 2 suns to one alone. The remains of stellar powder would be also abundant around II) BINARY SYSTEM VERY APART AMONG THEM (50 to 500 UA). III) OUR PLANETARY SYSTEM (3-50 UA, separated) has little or, stellar absent powder. If 2 suns are distant among them like the distance Sun-Jupiter (5 UA) or Sun-Pluto (40 UA), it would be unlikely that they houses a family of planets.

Según nota aparecida en el ultimo numero del Astrophysical Journal, el Multiband Imaging Photometer for Spitzer a bordo del Spitzer Space Telescope de la NASA, reveló que sistemas planetarios maduros (condiciones de nacimiento de sistemas binarios), circundados por discos de polvo estelar (producidos por colisiones en cinturones planetesimales : asteroides, cometas y posiblemente planetas), serian mas frecuentes alrededor de I) Estrellas Dobles Estrechamente Unidas (0-3, Unidades Astronomicas –UA-. 1 UA= Distancia de la Tierra al Sol), que circundando a sistemas provistos de un solo sol. En estos casos, los soles se moverian rapidamente uno sobre el otro debido a la fuerza de la gravedad. Aunque según David Trilling, las fuerzas gravitacionales en estos sistemas pugnan por expulsar cualquier planetesimal al espacio, se sabe que existen docenas de planetas orbitando alrededor de un sol, de estos duos. En estos casos las puestas de sol serian similares a las observadas en nuestro planeta, excepto que el segundo sol seria avistado como una estrella brillante en la noche, lo que ha hecho postular a algunos que a lo mejor nuestro sistema solar tambien dispone de 2 soles. Teóricamente, existiria tambien la posibilidad de observar 2 soles poniéndose en el horizonte uno trás el otro.
En general, los sistemas binarios serian 2 veces mas frecuentes que los constituidos por un sol unico. El Spitzer no vé los planetas directamente, los deduce por la forma del disco de polvo generado por asteroides y cometas. El Spitzer encontró más discos de polvo alrededor de sistemas binarios estrechamente unidos, que alrededor de los constituidos por un solo sol, lo que quiere decir que los planetas prefieren 2 soles a uno solo. Los restos de polvo estelar tambien serian abundantes alrededor de II) sistemas binarios muy lejanos entre si (50 a 500 UA). III) Nuestro sistema planetario (3-50 UA, aparte), tiene poco o, ausente polvo estelar. Si 2 soles estuviesen distantes entre si, como la distancia Sol-Júpiter (5 UA) o Sol-Plutón (40 UA), seria improbable que albergasen una familia de planetas.
