Sentences with phrase «stable orbits around the star»

Not exact matches

Instead, it would have spent a long time in a stable orbit around a single star before encountering the dangerous influence of Alpha Centauri A and B.
Now, Hippke and Heller show that a combination of the stars» gravity and radiation pressure from their photons can bring the craft into a stable orbit around one of the stars, then around the tantalising planet (Astrophysical Journal Letters, doi.org/bx8t).
He pointed out that there are many close - orbiting planets around middle - aged stars that are in stable orbits, but his team doesn't know how quickly this young planet is going to lose its mass and «whether it will lose too much to survive.»
In a small number of the simulations, it eventually wound up in a stable orbit around one of the stars.
An Earth - type planet could have liquid water in a stable orbit centered around 0.036 AU from Star B — well within the orbital distance of Mercury in the Solar System.
An Earth - type planet could have liquid water in a stable orbit centered around 1.18 AU from Star A — between the orbital distances of Earth and Mars in the Solar System.
Assuming that the spectroscopic companion B does not preclude a stable inner planetary orbit, the distance from Star A where an Earth - type planet would be «comfortable» with liquid water is centered around only 0.457 AU — between the orbital distances of Mercury and Venus in the Solar System.
The analyses did not resolve whether the perturbing body orbits Sirius A or B, although dynamical simulations suggest that stable orbits exist around both stars at circumstellar distances up to more than half the binary system's closest separation of 8.1 AUs (Daniel Benest, 1989).
However, if the existence of a relatively close, second companion (see Star Bc below) around Bab — with an orbital period of 2.2 to 2.9 years or less — is confirmed, then a planetary orbit in Star Ba's water zone may not be stable over the long run.
An Earth - type planet could have liquid water in a stable orbit centered around 3.5 AU (within a predicted habitable zone ranging between 2.3 and 4.8 AUs) from Star A — between the orbital distances of the Main Asteroid Belt and Jupiter in the Solar System (NASA Stars and Exoplanet Database).
Indeed, stable orbits may extend as far as one third of the closest separation between any two stars in a binary system, but according to NASA's Kepler Mission team, numerical integration models have shown that there is a range of orbital radii between about 1/3 and 3.5 times the stellar separation for which stable orbits around two stars are not possible (Holman and Wiegert, 1999; Wiegert and Holman, 1997; and Donnison and Mikulskis, 1992).
