Suzaku Discovery of a Hard X-Ray Tail in the Persistent Spectra from the Magnetar 1E 1547.0-5408 during its 2009 Activity
Enoto, Teruaki; Yamaoka, Kazutaka; Makishima, Kazuo +8 more
The fastest-rotating magnetar 1E 1547.0-5408 was observed in broad-band X-rays with Suzaku for 33 ks on 2009 January 28-29, 7 d after the onset of its latest bursting activity. After removing burst events, the absorption-uncorrected 2-10 keV flux of the persistent emission was measured with the XIS as 5.7 × 10-1erg cm-2s…
Suzaku Observation of the Anomalous X-Ray Pulsar 1E 1841-045
Terada, Yukikatsu; Ueno, Masaru; Takahashi, Hiromitsu +7 more
We report on the results of a Suzaku observation of the anomalous X-ray pulsar (AXP) 1E 1841-045 at the center of the supernova remnant Kes 73. We confirmed that the energy-dependent spectral models obtained by previous separate observations were also satisfied over a wide energy range from 0.4 to ∼70 keV, simultaneously. Here, the models below ∼1…

Bilir, Selçuk; Demircan, Osman; Bakiş, Volkan +3 more
New high-resolution spectra of the short-period (P ∼ 1.76 days) young detached binary LT CMa are reported for the first time. By combining the results from an analysis of new radial-velocity curves and published light curves, we determine values for the masses, radii, and temperatures as follows: M1 = 5.59 (0.20) Modot, R
