The Mysteries of Alpha Centauri
01.04.2015
For printing
After long observations of the Alpha Centauri system, an international scientific group suggested that perhaps there is another super Earth present there.
For quite a long time, the research team did not have the opportunity to obtain the characteristics of the first super – earth (or super earth) found on the territory of the system alpha Centauri B b.
The very existence of the object was also questioned.
Last year and the year before that, the powerful Hubble telescope recorded the behavior of the alpha Centauri B star for 40 hours.
The observations took place during the entire period of the exoplanet's journey along the disk of the luminary.
The data obtained over two years strongly contradicted each other and could not be related to the impact of alpha Centauri A – another star in the system.
Such an effect could only be explained by the fact that there is another super Earth in the space system.
If this is the case, it becomes clear that the new exoplanet is located a little further from its own star, Alpha Centauri B, than the super Earth that was found earlier.
It overcomes its way around the sun in a little less than 20 and a half days.
As part of the research work, a special program was developed, including a continuous 26 hour observation of Alpha Centauri.
It will help to find evidence or, on the contrary, refute the fact of the presence of a second super earth in this system.
The main problem is that the capacities of modern telescopes are not enough, and the best observatories in the world are now engaged in other studies.
It is planned to use an orbiter for observations, its cost is about two million dollars.
Perhaps a scientific group interested in the study will be able to raise this considerable amount with the help of one of the crowdfunding platforms.
Earlier, another scientific group published the exact parameters of the first exoplanet found in the system.
It turned out that its mass is 2.7 times greater than that of our planet, which confirms its status as a super Earth.
Prior to this, it was suggested that it is a hot Jupiter.
Alpha Centauri B b moves around a star similar to the Sun, and is located at a distance of 4.37 sv.years from the Earth.
The exoplanet "lives" 0.04 AU from its own star and, possibly, moves so that one of its sides is constantly turned to Alpha Centauri B.
The possibility of the appearance of life on this exoplanet is extremely unlikely.
It is not yet clear when exactly the research of the system will begin for the detection of a second super Earth in it.
