X-ray Study of Rekindled Accretion in the Classical Nova V2491 Cygni

We conducted an X-ray spectroscopic study of the classical nova V2491 Cygni using our target-of-opportunity observation data with the Suzaku and XMM-Newton satellites as well as archived data with the Swift satellite. Medium-resolution ( $R$$\sim$ 10–50) spectra were obtained using the X-ray CCD spectrometers at several post-nova epochs on days 9, 29, 40, 50, and 60–150 in addition to a pre-nova i...
