GCIRS 16SW
GCIRS 16SW, also known as S97, is a contact binary star located in the Galactic Center. It is composed of two hot massive stars of equal size that orbit each other with a period of 19.5 days. The stars are so close that their atmospheres overlap, and the two stars form an eclipsing binary varying in brightness by 0.35 magnitudes at infrared wavelengths. GCIRS 16SW was classified as a candidate luminous blue variable on the basis of its spectrum and physical properties. This was before it was identified as an eclipsing binary, but it is still treated as a candidate LBV.
