PW Boo is a star  presently classified as an RR Lyrae variable by the AAVSO International Variable Star Index. Stars of this type are particularly significant in astronomy for their use as standard candles, aiding in the determination of distances within our galaxy.

The data for this analysis was sourced from the AAVSO, as well as light curve measurements from ASAS and ASAS-SN, which provided the necessary photometric information. The period of PW Boo was identified to be 0.5952084 days, fitting the expected light variation profile for RR Lyrae variables, with the magnitude oscillating between 12.48 and 13.64. The epoch marking the star’s peak brightness was calculated to be HJD 2458597.929.

Additional data, particularly the star’s precise location and photometric details, were verified against Gaia mission data, ensuring the accuracy of the analysis. The phase plot constructed from the compiled data exhibits the shape and amplitude consistent with an RRab subtype of RR Lyrae variables, known for their asymmetric light curves with steep ascensions.

In conclusion, the thorough examination of PW Boo’s properties supports its standing as an RR Lyrae variable. This work contributes to the ongoing refinement of variable star catalogs, crucial for the accurate measurement of astronomical distances and the understanding of stellar behavior.
