We report detailed X-ray observations of the unique binary system $\epsilon$ Lupi, the only known short-period binary consisting of two magnetic early-type stars. The components have comparably strong, but anti-aligned magnetic fields. The orbital an

A new benchmark of soft X-ray transition energies of

Publikováno v: The European physical journal. D, Atomic, molecular, and optical physics. 76(3)

A key requirement for the correct interpretation of high-resolution X-ray spectra is that transition energies are known with high accuracy and precision. We investigate the K-shell features of

We present XMM-Newton observations of 2 Velorum (WR11, WC8+O7.5III, P =78.53 d), a nearby Wolf-Ray binary system, at its X-ray high and low states. At high state, emission from a hot collisional plasma dominates from about 1 to 8 keV. At low state, p

Measurement of anomalously strong emission from the 1s-9p transition in the spectrum of H-like phosphorus following charge exchange with molecular hydrogen

Autor: M A, Leutenegger, P, Beiersdorfer, G V, Brown, R L, Kelley, C A, Kilbourne, F S, Porter

Publikováno v: Physical review letters. 105(6)

We have measured K-shell x-ray spectra of highly ionized argon and phosphorus following charge exchange with molecular hydrogen at low collision energy in an electron beam ion trap using an x-ray calorimeter array with ∼6 eV resolution. We find tha
