NICER observation list: Target ID 660802

Abstract

We are requesting for a joint NICER and Swift (X-ray + UV) monitoring of two X-ray bright, repeating stellar tidal disruption events (TDEs) AT2018fyk and eRASStJ045650. Joint NICER+Swift campaign over the past 4 years (2018-2022) has captured a second outburst from these TDEs which has been interpreted as the signature of a repeating partial disruption. Our main goals are 1) to capture the full evolution of AT2018fyk's second outburst and additional outbursts from eRASStJ045650, and 2) acquire high-quality X-ray and UV data during these subsequent outbursts and compare them with previous flares. Our goals require long-term monitoring, high quality X-ray spectra, high X-ray sensitivity, and UV coverage. This makes NICER+Swift the best combination for this study.
