Wells & Mendip Astronomers own Dr Ben Sutlieff is co-lead in a new exoplanet discovery - the lightest exoplanets ever observed from Earth at only 2.4 Jupiter masses and it's only 63 light years away. Find out more at: https://www.eso.org/public/news/eso2609/
A team of astronomers have discovered a third planet orbiting the star Beta Pictoris. The new planet, Beta Pictoris d, is 100 times fainter than Beta Pictoris b — the first planet discovered in the same system — and is among the lightest exoplanets ever to be imaged from the ground. After spotting the planet using the European Southern Observatory’s Very Large Telescope (ESO’s VLT), the team found it had been hiding in archive observations spanning more than a decade.
“This was a serendipitous discovery,” says Ben Sutlieff, co-lead of the study published today in The Astrophysical Journal Letters and astronomer at the University of Edinburgh, United Kingdom. “We initially wanted to look more at a known planet in the system, Beta Pictoris b, to see how it changed over time,” he adds. However, when the team went to analyse their images of the system, they noticed something else, separated from Beta Pictoris b, that led them down an entirely new path.
