Mysterious eclipses point to giant ringed Jupiter like planet
Scientists have found evidence of a giant ringed gas planet which may be up to fifty times more massive than Jupiter, orbitting a star over thousand light years away from Earth. Researchers had earlier identified that the light from the rare young star is regularly blocked by a large object. They now predict that these eclipses are caused by the orbit of the yet undiscovered giant planet.
London : Scientists have found evidence of a giant ringed gas planet which may be up to fifty times more massive than Jupiter, orbitting a star over thousand light years away from Earth. Researchers had earlier identified that the light from the rare young star is regularly blocked by a large object. They now predict that these eclipses are caused by the orbit of the yet undiscovered giant planet.
Using data from the Wide Angle Search for Planets (WASP) and Kilodegree Extremely Little Telescope (KELT), researchers from including those from the Harvard University in the US, analysed fifteen years of the star's activity. "We found a hint that this was an interesting object in data from the WASP survey," said Hugh Osborn, from the University of Warwick in the UK, who discovered the unusual light curve.
"It wasn't until we found a second, almost identical eclipse in the KELT survey data that we knew we had something special," said Osborn. They discovered that every two and a half years, the light from the distant star PDS 110 is reduced to thirty per cent for about two to three weeks.
"What's exciting is that during both eclipses we see the light from the star change rapidly, and that suggests that there are rings in the eclipsing object, but these rings are many times larger than the rings around Saturn," said Matthew Kenworthy, astronomer at the Leiden Observatory in the Netherlands. The next eclipse is predicted to take place in September this year. Gathering new data will help ascertain precisley what is causing the mysterious eclipses.
