... A correlation between metal abundance and orbital elements (the eccentricity and angular momentum) has been found for three semples of disk stars of our Galaxy with abundance derived from detailed analysis. The correlation indicates that metal abundance in the Galaxy kept increasing after the birth of old disk stars and that the Galaxy kept collapsing during the formation of its disk subsystems. ...

... Activities | ... Collaborations | ... The main objective of laboratory #235 is development of imaging array detectors for different applications (including radio-astronomy, safety and security systems). We develop ultra-sensitive detectors (bolometers) and detector arrays, planar antennas and tuning circuits, refractive and reflective quasi-optical systems focusing millimeter and sub-millimeter wave irradiation on the detectors. ...
