Abstract Details

Photographic plates in the Harvard collection show the star V1835 Aql brightening by a factor of 100 in flux over four years starting in 1899, remaining at maximum for four years, then declining below the depth of the plates \cite{williams2005}. This nova-like behavior is very atypical for most variable stars and as a result there has been much debate over the exact nature of V1835 Aql. This debate was ended by the discovery of a Raman scattered emission line at 6824 \AA, which is unique to symbiotic binaries and unequivocally identifies V1835 Aql as a symbiotic star \cite{bk12}. Our research hopes to expand upon our knowledge of V1835 Aql through analysis of five years worth of multi-band optical time-series photometry. From this we have found the period of this star to be 419 days. This long period confirms that V1835 Aql is a symbiotic star and not its closer orbiting cousin, a cataclysmic variable. We have also determined the properties of all the other variable star candidates near V1835 Aql, of which there are 31.
