Peter Pan Disk

Date of the discovery: 14 October 2016

Short Description: AWI0005x3s or WISE J080822.18-644357.3 was discovered as an M-dwarf in the 45 Million years old Carina Association (a young moving group). While all the gas in the disk should have accreted or the gas should have been blown away in the first 20 Million years of the systems existence, WISE J080822.18-644357.3 shows large infrared excess and a warm disk. This is evidence for a lot of gas and therefore this object is suspected to be an unusually old Young Stellar Object. Just like the lost boys in Peter Pan the disk does not seem to grow up.
