A Candidate Transit Event around Proxima Centauri

الأصل · EN

We present a single candidate transit event around Proxima Centauri, found during a blind transit search using a robotic 30cm telescope at Las Campanas Observatory. The event lasted 1 hour, with an estimated depth of 5mmag, and is inconsistent with the transit window predicted for the recently discovered planet b. We modeled the lightcurve under the assumption that the event was caused by a transiting exoplanet, and our model predicts the planet has a radius R 1 R⊕. We encourage continued monitoring of Proxima to elucidate the origin of this event.
