Аннотация:The binary system V 361 Lyr is assumed to be observed at the first mass
exchange evolutionary stage when the brighter and more massive star is
outflowing to its low-mass companion. A number of such binaries must be
considerably less than those at the second mass exchange stage (i.e., CVs),
after the common envelope phase and shrinkage of the system. The first mass
exchange can be realized only in the binaries with initially small separations
between the components. Hence it is rather serendipitous chance to observe
such a system.
