When astronomers want to discover and see the existence of a new planet outside the sun, they give it time to complete three orbits. Nevertheless, this method has its flaws because it can not check the existence of a planet for long periods. The method is ideal only for short periods like days or months.
However, some astronomers under the supervision of the University of Geneva have found a way to overcome this challenge. The newly developed technique allows them to confirm the presence of a planet in a few months or even up to ten years.
The technique of transits involves the detection of a hollow in the glare of the host star, especially when the planet passes. The method is therefore ideal for identifying exo-planets. It also helps to estimate the radius of a planet and the angle of the orbit that is applicable to a massive number of stars
However, the method has its fair part of the disadvantage, considering that it is mandatory to wait until the suspected planet moves in front of the star at least three times. It is therefore only useful in the detection and identification of planets in orbit for short periods, especially a few days or months. If the method were to be used, it would take more than thirty years to identify a planet that resembles Jupiter, which often takes eleven years into orbit.
However, a team of astronomers led by Helen Giles has developed a way to handle this challenge. . Astronomers have evaluated data from a K2 model space telescope that suggested a temporary decline in brightness over long periods as well as the likelihood that a planet will move in front of a star. Astronomers had to evaluate a large number of light curves
Helen Giles analyzed new Gaia mission results in order to establish the length and distance of the star marked EPIC248847494. The data that she has acquired have established that the location of the planet is about 4.5 times larger than the distance between the sun and the earth. Therefore, an orbit takes about ten years to complete.
The only question that remains unanswered is that of a planet or a star. However, the solution will soon be found by a telescope based in Chile. Helen Giles also managed to assume the mass of the planet by evaluating the radial velocity of the star. She found that the mass of the object is thirteen times smaller than that of Jupiter, which is well below the minimum weight of a star
Helen is optimistic about the possibility of a "lightning bolt". use this new method to search for other planets.
