New photometric data set of the early type contact binary
V 382 Cyg have been analyzed with emphasis on determining
the photometric mass ratio of the system. The result (
)
supports the value given by Popper & Hill (1991). A study of the system using new data shows a period
increase of about 3.28 s per century, which corresponds
to a very large rate
of mass
transfer from the less massive to the more massive component under
the conservative mass transfer hypothesis.
Key words: stars: binaries: eclipsing / stars: individual: V 382 Cyg
