Possible Suzaku detection of non-thermal X-ray signals from a rotating magnetized white dwarf

Mukai, K.; Nakamura, R.; Enoto, T. +7 more

Although rotating neutron stars (NSs) have been regarded as being textbook examples of astrophysical particle acceleration sites for decades, details of the acceleration mechanism remain a mystery; for example, we cannot yet observationally distinguish “polar cap” models from “outer gap” models. To solve the model degeneracy, it is useful to study…

Oxygen line mapping of SN 1006 with Suzaku

Petre, Rob; Katsuda, Satoru; Tsujimoto, Masahiro +25 more

SN 1006 is one of the supernova remnants (SNRs) with relatively low-temperature electrons, considering the young age of just 1000 years. We carried out SN 1006 mapping observations with the X-ray Imaging Spectrometers (XIS) and the Hard X-ray Detector (HXD) onboard Suzaku, the fifth Japanese X-ray satellite. Thanks to the excellent spectral resolu…
