HD 192685, also known as QR Vul or HR 7739, is a star 1,199 ly away in the Vulpecula constellation. It is visible to the naked eye. It is a Be star and is slightly variable.[2] From October to December 1982 the Hydrogen alpha absorption line increased in emission strength by 30%.[3] The line is partially filled by redshifted emission.[4]
HD 192685 has excess infrared emissions (12-100 μm) which are interpreted to be free-free radiation in the gas surrounding the star.[5]
