On the Amplitudes of Superhumps
J. Smak
TL;DR
This paper compares simulated bolometric light curve amplitudes with observed superhump amplitudes, revealing a significant discrepancy that challenges the tidal model of superhumps.
Contribution
It demonstrates that simulated amplitudes are about ten times lower than observed, indicating a major failure of the current tidal model of superhumps.
Findings
Simulated bolometric light curve amplitudes are about 10 times lower than observed superhump amplitudes.
The discrepancy suggests the tidal model does not fully explain superhump phenomena.
Highlights the need for alternative models or revisions to current theories.
Abstract
Amplitudes of bolometric light curves produced by 2D and 3D simulations are used to determine the corresponding visual amplitudes. They turn out to be about 10 times lower than typical amplitudes of superhumps. This means a major failure of the tidal model of superhumps.
