OGLE small-amplitude variables in the Galactic bar
OGLE small-amplitude variables in the Galactic bar
Among over 200,000 Galactic Bulge variable stars in the public domain OGLE catalogue, we found over 15,000 red giant variables following two well defined period -- amplitude relations. The periods are in the range 10 < P < 100 days, and amplitudes in the range 0.005 < A < 0.13 …
