Can estimate a planet’s magnetic field
A group of Russian and Austrian scientists published in the journal Science a new method to estimate the magnetic field enables a remote exoplanets – planets outside our solar system and orbiting another star – bearing planet HD 209458b name.
In the two decades since the discovery of the first planet outside our solar system, astronomers have been major advances in the study of this type of object. While 20 years ago, the discovery of a new planet is a big event for astronomers but now they can study the moon, air, climate and other characteristics of the this planet similar to that of the planets in the solar system. For both types of solid planets and gaseous planets, the important feature of them is magnetic and magnitude. On Earth, these features help protect living organisms avoid dangerous radiation of the universe and helps animals live on earth can move.
Kristina Kislyakova Space Research Institute – Austrian Academy of Sciences in Graz, along with a team of international physicists first had to estimate the value of the magnetic moment and magnetic shape of an exoplanet (HD 209458b planet). In that group there Khodachenko Maxim, a researcher at the Department of radiation and computational methods – Nuclear Physics Institute of the University of Skobeltsyn countries Matxccova (Russia).
HD 209458b planet (Osiris) is regarded as a hot Jupiter. It is about a third of Jupiter. It is a gas giant planet orbiting very close heat against the star HD 209458. The planet HD 209458b complete one revolution around the star took only 3.5 days. This planet has been known to astronomers for a long time and studied. In particular, this is the first planet detected the atmosphere. So, for many scientists it has become an object model for the development of his theory.
