A Close Look at Newborn Planets Reveals Hints of Infant Moons | Quanta Magazine
To find the second planet and provide even further confirmation for the first one, a team led by Sebastiaan Haffert at Leiden University in the Netherlands used MUSE, a new instrument on the VLT, to search for emission from hydrogen. The first planet, dubbed PDS 70b, prowls right outside the inner edge of this gap in the disk. “PDS 70 is really becoming a benchmark system,” said Julien Girard, an astronomer at the Space Telescope Science Institute who collaborated on the discoveries of both the second planet and the possible moon-forming disk.
