NICER observation list: Target ID 771401

We propose a 50 ks observation of the Accretion Disk Corona (ADC) candidate MS 1603.6+2600 with NuSTAR and 10 ks with NICER. With the broadband spectra, we will accurately model the X-ray continuum, which is suspected to either originating via reflection off the accretion disk or through inverse Compton scattering in the accretion column. We will also measure the energy dependent eclipse depths in MS 1603.6+2600 to map the origin of hard and soft X-rays. In addition, we will search for pulsations in the NuSTAR lightcurves as well as explore for the presence of quasi-periodic oscillations (QPOs) or cyclotron line attributed to the neutron star in MS 1603.6+2600.
