NICER observation list: Target ID 260501

Abstract

Habitability of the Earth-like planet in the closest neighborhood Proxima Centauri is greatly affected by central stellar activities. A 83-day rotational period of Proxima Centauri was recently detected by optical monitoring. Interestingly, there is a signature for X-ray variation to be anti-correlated with this optical periodic modulation, suggesting sunspot activities. However, this anti-correlation has yet to be confirmed due to poor X-ray photon statistics and uncertainties of contamination from stellar flares. Here we propose two-month NICER monitoring (5 ks x 20 visits) of Proxima Centauri from April to June simultaneous with a planned optical survey by a new satellite TESS to find a conclusive evidence for the anti-correlation.
