Observations Requested of Exoplanet Proxima Centauri b
Abstract:
Dr. Karen Collins (Vanderbilt University) has requested ground-based, follow-up observations of recently discovered exoplanet Proxima Centauri b. This exoplanet is a suspected Earth-size planet orbiting in the habitable zone of our nearest stellar neighbor, Proxima Centauri (V645 Cen).
Justification:
There exists a rough ephemeris of this target based on radial velocity measurements, so the predicted mid-transit times can vary +/- 6 hours. Therefore, it is requested that observations be as long as possible. The expected duration of the transit is less than two hours long. The transit depth is expected to be 5 mmag. However, because Proxima Centauri itself is a flare star, there may be large variations in the light curve.
