Abstract (from CDS):

New photometric data set of the early type contact binary V382 Cyg have been analyzed with emphasis on determining the photometric mass ratio of the system. The result (q=0.68) supports the value given by Popper & Hill (1991AJ....101..600P). A study of the system using new data shows a period increase of about 3.28s per century, which corresponds to a very large rate ∼5.0x10–6M/yr of mass transfer from the less massive to the more massive component under the conservative mass transfer hypothesis.
