A Multiple System iUMA |
Russian version |
Recent studies indicate that stars are most likely forming within the
binary and multiple systems. In our Galaxy, according to various
estimates, at least 50 percent of stars have companions. Therefore,
the study of binary and multiple stars is important for understanding
the mechanisms of star formation in general. During several years we
are conducting the observations of such multiple stellar systems at
the BTA telescope in order to find their companions and study the
properties therein. A speckle interferometer, designed and manufactured
at the observatory is used for the observations. This instrument, in
particular, can detect companions of stars at the angular scales of
up to a hundredth of a second of arc.
