Poles Led by a team of scientists has discovered three new planetary systems. Observations were made using the Hobby-Eberly Telescope in Texas.

The discovery of three extrasolar planetary systems made by a team of researchers led by prof.Aleksandra Wolszczan and prof. Andrew Niedzielskiego – tells website Nicolaus Copernicus University in Torun.

The researchers conducted observation using the Hobby-Eberly Telescope (HET) in Texas. The project started 10 years ago and brought the discovery of planetary systems 17 and 20 planets.

The elongated orbit around a red giant star named BD + 49 828 circling the planet BD + 49 828b similar to the one that Jupiter Solar System. Its time circulation around the star is 2,590 days. Scientists estimate that the planet can “survive” a star because of its distance from it (4.2 astronomical units).

around the object HD 216536 circling at a distance of 0.61 astronomical units planet whose orbit comparable This is followed by moving Mars. This forces the planet HD 216536b to extinction because its star has a diameter of 8 to 20 rays of the sun and already exhausted “fuel” hydrogen.

On the other hand, about a third star, named HD 95127 planet circling a weight of 5 Jupiters . It orbits at a distance of 1.28 I

All three stars are red giants that have completed hydrogen burning and have started or will start burning helium.
