HD 192685, also known as QR Vulpeculae or HR 7739, is a Be star about 1,000 ly away in the Vulpecula constellation. It is visible to the naked eye.
Description.
HD 192685 varies slightly in brightness and is classified as a γ Cassiopeiae variable.
From October to December 1982 the Hydrogen alpha absorption line increased in emission strength by 30%. The line is partially filled by redshifted emission.
HD 192685 has excess infrared emissions (12-100 μm) which are interpreted to be free-free radiation in the gas surrounding the star.
Companions.
It has at least one companion with separation 0.55" and magnitude 7.55, and may also be a long-period spectroscopic binary.
