A SuperWASP Light Curve Displaying a Single Long-duration Transit: A Jupiter Size Exoplanet in a Very Distant Orbit?
Abstract
We present the SuperWASP light curve of a 10th magnitude A7V star containing a single, well-defined U-shaped transit-like event lasting around 11 days with a depth of 1.1%. The star is otherwise non-variable throughout the 8 yr duration of the observations. If the event is modeled as an exoplanet transit, it is compatible with a 1.8 R J exoplanet in a ~205 au orbit with a period of ~2200 yr.
