NICER observation list: Target ID 766327

Abstract

We request 112 ksec of NICER observing time to study the interaction between the solar wind and two bright periodic comets, 12P/Pons-Brooks and 62P/Tsuchinshan. Utilizing NICER's agility and sensitivity, we aim to compare charge-exchange spectra arising from the comets' interaction with varied solar-wind states. Simultaneous observations of both comets at distinct solar latitudes allow us to compare spectra from differing solar-wind conditions. This offers a unique opportunity to map the solar wind during solar maximum and explore charge-exchange reactions in astrophysical plasmas spanning a 0.1-10 MK temperature range.
