NICER observation list: Target ID 567501

Abstract

We request 52 ksec of observation time in NICER AO4 to continue monitoring the X- ray emission from the massive colliding wind binary Eta Carinae (η Car). NICER started to observe η Car s X-ray emission as part of NICER Observatory Science Program and continued in cycles AO1, AO2, and AO3. If accepted the NICER AO4 will complete a whole cycle from apastron to apastron (∼5.54 years) of monitoring program. The NICER AO4 will cover η Car s orbital phases between ∼4.37 and ∼4.55 providing time-resolved spectrometry of η Car s at apastron. Flux observations from NICER AO4, together with observations from NICER AO3, will be compared with RXTE observations at the same orbital phases to show changes in the mass loss of the stars.
