According to the recent findings of Scientists, there is hellish – really hot – world where even the surface of the planet is over 4,000C, nearly as hot as the Sun. This, in part, is because of the KELT-9b – a host star that is very hot. KELT-9b takes only two days to complete one orbit of the star.
Planet as almost twice as big as Jupiter: Gaudi
The planet cannot survive for a very long time if it is this close because the gases in its atmosphere are lost to space and are being blasted with radiation. Another bizarre aspect of this discovery is that according to the researchers, the host star may look a little like a comet when it circles the star from pole to pole.
You can read the report about the KELT-9b in the journal Nature. On Monday, the highly unusual properties of the host star were presented to the spring meeting of the American Astronomical Society in Austin, Texas as well. In an interview to BBC News, Prof Scott Gaudi, from The Ohio State University, said “We found [KELT-9b] back in 2014, if you can believe it; and it took us this long to finally convince ourselves that this truly bizarre and unusual world was in fact a planet orbiting another star.”
Gaudi added, “We know pretty well how big the planet is and how massive it is: it’s about three times the mass of Jupiter and twice as big as Jupiter. We know the parent star’s properties reasonably well: it’s about two and a half times more massive than the Sun; it’s almost twice as hot as the Sun; and it’s rotating very rapidly and so it would appear very flattened to our eyes.”
Planet presents the same face always
The planet, notes the report by the news site BBC News, is locked to its star neatly, which means that it is presenting the same face. The Moon never shows its far side to Earth in the same way. The host star is known by the simple designation of KELT-9. It radiates so much ultraviolet light that it may erode the atmosphere of the planet completely.
This star is termed as an A-Type object, notes BBC News. These stars, which exist for only millions of years instead of billions of years, burn brilliant but brief lives. Hence, in a short time, KELT-9 may puff up after it exhausts its fuel and eats the planet. This discovery was made by the scientists with the use of robotic telescope system, which uses standard and high-end camera telephoto lenses attached to scientific grade detectors.
The system is being operated by the Ohio State University at two locations, one in the southern hemisphere and one in the northern hemisphere. The astronomical facility is called the Kilodegree Extremely Little Telescope. Prof. Gaudi said, “We named the telescope kind of as a joke; we’re poking a little fun at ourselves.” The study is a collaboration with the South African Astronomical Observatory, Vanderbilt University, and Lehigh University.
