X-ray Iron absorption line in Swift J1858.6-0814
Kazumi Asai, Tatehiro Mihara, Kento Sakai +1
We present the spectral analysis of bright steady states in an outburst of the transient neutron star low-mass X-ray binary (NS-LMXB) Swift J1858.6-0814 observed with NICER. We det…
Decades' long-term variations in NS-LMXBs observed with MAXI/GSC, RXTE/ASM and Ginga/ASM
Kazumi Asai, Tatehiro Mihara, Masaru Matsuoka
We investigated the decades' long-term X-ray variations in bright low-mass X-ray binaries containing a neutron star (NS-LMXB). The light curves of MAXI/GSC and RXTE/ASM covers $\si…
Hard-tail emission in the soft state of low-mass X-ray binaries and their relation to the neutron star magnetic field
Kazumi Asai, Tatehiro Mihara, Masaru Mastuoka +1
Average hard-tail X-ray emission in the soft state of nine bright Atoll low-mass X-ray binaries containing a neutron star (NS-LMXBs) are investigated by using the light curves of M…
X-ray variability with spectral state transitions in NS-LMXBs observed with MAXI/GSC and Swift/BAT
Kazumi Asai, Tatehiro Mihara, Masaru Matsuoka +1
X-ray variabilities with spectral state transitions in bright low mass X-ray binaries containing a neutron star are investigated by using the one-day bin light curves of MAXI/GSC (…
Sudden End of X-Ray Outbursts around Periastron of Circinus X-1 Observed with MAXI
Kazumi Asai, Tatehiro Mihara, Masaru Matsuoka +5
MAXI/GSC observed 21 outbursts from Circinus X-1 between 2009 August and 2013 December. Although 14 outbursts showed ordinary gradual decays, in 7 outbursts we found sudden luminos…
Propeller-Effect Interpretation of MAXI/GSC Light Curves of 4U 1608-52 and AqlX-1 and application to XTE J1701-462
K. Asai, M. Matsuoka, T. Mihara +6
We present the luminosity dwell-time distributions during the hard states of low-mass X-ray binaries containing a neutron star, 4U 1608-52 and AqlX-1, observed with MAXI/GSC. The l…
