A new method of searching for distant planets


Detect distant planet - it’s quite a challenge for astronomers, because it represents a small dim facility, located near their parent stars. Two of the most effective ways to search for planets were considered to be the method of radial velocities of stars or swaying search and search twinkling stars - a method of transits. However, researchers at Tel Aviv University, together with experts from the Harvard-Smithsonian Center for Astrophysics exoplanet unable to access recently, thanks to a new method, based on the special theory of relativity of Einstein.

According to scientists, the essence of the new method is to observe 3-effects that arise in the period of the planet around the star. For instance, one of the effects called "The effect of radiation" (beaming effect) Einstein leads to the fact that the star seems brighter when approaching us as a result of gravity of the planet, and, conversely, dimmer - at a distance from our star. The reason is that with the "accumulation" photon energy increases the brightness. An increase in brightness due to the focusing of light in the direction in which the star is moving.

"Planet of Einstein", the official name of which Kepler-76b, is a hot Jupiter. Its orbital period of revolution around its star is 1.5 days. The diameter of the planet more than 25% of the diameter of Jupiter, and the mass is greater than twice the mass of the giant of the solar system. The planet orbits the star of spectral type F, which is located in the constellation Cygnus at a distance of 2,000 light-years from Earth.
