Abstract

Up to now we have evidence for some 15 planets moving in double stars. They are all of the so-called S-type, which means that they are orbiting one of the primaries. Only two of the binaries have separations in the order of the distances where the planets in our Solar system orbit the Sun, namely Gliese 86 and ϒ Cep. In this study we investigate the stability of the recently discovered planet in ϒ Cep with respect to the orbital parameters of the binary and of the planet. Additionally we check the region inside and outside the planet’s orbit (a = 2.1 AU). Even when the mass of an additional planet in 1 AU would be in the order of that of Jupiter, the discovered planet would be in a stable orbit.

Resumen

Hasta ahora se tiene evidencia de unos 15 planetas en órbita alrededor de estrellas dobles. Todos pertenecen al llamado tipo S, es decir, orbitan en torno a la primaria. Sólo dos de las binarias, Gliese 86 y ϒ Cep, tienen separaciones del orden de las dimensiones de las órbitas en el Sistema Solar. En este estudio, investigamos la estabilidad del planeta en ϒ Cep en relación a los parámetros orbitales de la binaria y del planeta. Además, investigamos la región dentro y fuera de la órbita del planeta (a = 2.1 AU). Aún si la masa de un planeta adicional a 1 AU fuera del orden de la masa de Júpiter, el planeta descubierto tendría una órbita estable.
