A Search for Superhumps in the Cataclysmic Variable SW Sextantis

TL;DR

This study conducted photometric observations of SW Sextantis to detect superhumps, finding none, which suggests superhumps are not characteristic of this class of cataclysmic variables.

Contribution

The paper provides the first detailed search for superhumps in SW Sextantis, challenging assumptions about their presence in this star class.

Findings

No superhumps detected in SW Sextantis

Superhumps are not a defining feature of SW Sex stars

Supports diversity in accretion disk behaviors

Abstract

We present differential photometry of the cataclysmic variable star SW Sextantis. A time series analysis was performed in search of superhumps in the accretion disk of this star, which is the prototype of a class of cataclysmic variables, the SW Sex stars. We find no superhumps, which shows that the presence of superhumps is not a defining feature of the SW Sex stars.
