Photometric and Spectroscopic Investigations of Three Large Amplitude Contact Binaries

Photometric and Spectroscopic Investigations of Three Large Amplitude Contact Binaries

We performed photometric and spectroscopic studies of three large amplitude contact binaries: NSVS 2418361, ATLAS J057.1170+31.2384, and NSVS 7377875. The amplitudes of these three systems’ light curves are more than 0.7 mag. We analyzed the light curves using the Wilson–Devinney code to yield physi...
