A concept for the X-ray telescope system with an angular-resolution booster
Yoshitomo Maeda, Ryo Iizuka, Takayuki Hayashi +7
We present a concept of the X-ray imaging system with high angular-resolution and moderate sensitivity. In this concept, a two-dimensional detector, i.e., imager, is put at a sligh…

Variation of mass accretion rate onto the white dwarf in the dwarf nova VW Hyi in quiescence
Nozomi Nakaniwa, Takayuki Hayashi, Mai Takeo +1
We have analysed a series of Suzaku data and one dataset of XMM-Newton of the SU UMa type dwarf nova VW Hyi in optical quiescence. The observed spectra in the 0.2-10 keV band are m…
