Description
MAXI provides us with a powerful tool for detecting soft X-ray transients, such as outbursts of LMXBs or HMXBs, long-duration X-ray bursts, and stellar flares. To investigate more detailed physical processes of these X-ray transients, it is important to obtain the precision timing and spectroscopy data by rapid follow-up observations with high-sensitivity X-ray detectors. The Neutron Star Interior Composition Explorer (NICER), which was installed on ISS in June 2017, has the capability of rapid response to the newly reported MAXI transients and high-sensitivity X-ray timing and spectral observations. Moreover, NICER enables short high cadence observations of these transients. We report on the results of successful collaboration between the MAXI and NICER teams so far.
