Hereford Arizona Observatory found fluctuations in what type of main-sequence star in Cygnus?
Hereford Arizona Observatory Hereford Arizona Observatory (HAO), IAU-code G95, is an astronomical observatory, owned and operated by amateur astronomer Bruce L. Gary. Gary is the author of many publications related to astronomy, including "Exoplanet Observing for Amateurs" (2008), currently available in a second edition (2009). Observational studies of unusual starlight fluctuations in KIC 8462852 and WD 1145+017 are recent interests.
HD 92945 HD 92945 is a K-type main sequence star in the constellation of Hydra. Its apparent visual magnitude varies by 0.02 magnitudes and is approximately 7.72 at maximum brightness. A debris disk has been observed around the star by coronagraphic imaging, using the ACS and NICMOS instruments on the Hubble Space Telescope. It appears to extend 45 to 175 astronomical units from HD 92945 and is inclined at approximately 29 degrees.
