I'm still curious about pic related (Don't mind the glitch)

Does it really fit a multi mode pulsar? Does anyone know?

When i zoomed in, it looked exactly like the graph (although stretched), but it's kinda hard to see on the unzoomed graph.
I didn't manage to favorite the star, so I can't find it now, I couldn't find the direct link to the star when i found it because i was not logged in :<

Apart from the glitch, what the hell is this?

When i zoom in, i see something that looks like a function sin(20t)*sin(t)

Is the pulsating luminosity caused by the doppler effect or what usually causes the luminosity to pulsate? I don't really know a lot about astronomy, but now I'm kinda curious.
