The Astronomers discovered a triple star system in Planet with a gas giant planet which similar in size of Jupiter. A binary system which previously thought to be single is now actually a pair of stars revolving one another and are a part of triple star system said the Researchers at Harvard Smithsonian Centre for Astrophysis in the US.
Rare Triple Star Planet Discovered By Astronomers
“Known planets with three stars appearing in their sky are rare—the new discovery is just the fourth and the closest one yet, allowing for a better look than has been possible,” researchers said.
Along with the other stars, the main star is also highlighted according to the study of stars and planets. In this new system KELT – 4Ab, which has a gas giant planet which is similar to the size of Jupiter. The other stars named KELT-B and C are very much farther which revolve one another approximately.
“It takes the pair approximately four thousand years to orbit KELT-A, Phys.org reported. The view from KELT-4Ab would likely be one where its sun, KELT-A, would appear roughly forty times as big as our sun does to us due to its close proximity”, researchers said. They also said, “On the other hand, the two other orbiting stars would appear much dimmer due to their great distance, shining no brighter than our moon.”
“The binary system KELT-4BC may be what ultimately drove the planet KELT-4Ab so close to its star,” Jason Eastman, a research associate at the Harvard-Smithsonian Center for Astrophysics and lead author of a study published in the Astronomical Journal, told Space.com.
“Exactly how they got so close is an outstanding question, but one theory is that it migrates due to hot interactions with a third body — in this case, the third and fourth bodies KELT-BC,” Eastman told Space.com.
