Based on the changes in the light curve and the behavior of the series of spectra, this is a<u> binary system. </u>
<h3>How is this is binary system?</h3>
The characteristics described are those of a binary system with the specific type of system being the spectroscopic binary system.
This is because in a spectroscopic binary system, there won't be significant changes in brightness but as a result of stars orbiting towards and then away from us, spectral features will appear as alternative absorption lines.
In conclusion, this is a binary system.
