The identification of the long – period X – ray pulsar 1 WGAJ 1958 . 2 + 3232 with a Be – star / X – ray binary ⋆
We present the results of optical observations performed between May and September 1998 of the stars within the position error circle of the recently discovered ∼12 min pulsating X–ray source 1WGA J1958.2+3232. Based on photometry and slitless spectroscopy, we selected a likely optical counterpart, which was subsequently determined to be a m V =15.7 B0Ve star, the spectral properties of which a...
متن کاملA radio pulsar/x-ray binary link.
Radio pulsars with millisecond spin periods are thought to have been spun up by the transfer of matter and angular momentum from a low-mass companion star during an x-ray-emitting phase. The spin periods of the neutron stars in several such low-mass x-ray binary (LMXB) systems have been shown to be in the millisecond regime, but no radio pulsations have been detected. Here we report on detectio...
متن کاملThe identification of the transient X - ray pulsar Cepheus X - 4 with a Be / X - ray binary ?
We present long slit spectral (375-725 nm) observations of the proposed identification of the transient 66s Xray pulsar Cep X-4=GS2138+56. Spectra show features typical of Be/X-ray binaries. Superimposed on a weak emission from the IC 1396 nebula, strong Hα (4.5 nm EW) and Hβ (0.3 nm EW) lines are seen in emission with the other Balmer lines in absorption. Significant interstellar absorption fe...
متن کاملX–RAY EMISSION OF THE PULSAR–Be STAR BINARY PSR 1259–63*
X–rays are detected from the pulsar–Be star binary PSR 1259−63 only after apastron passage. We suggest that the X–rays result from accretion on to the pulsar magnetosphere of matter captured from the Be star wind. The capture efficiency changes markedly at this phase, in line with the observations, provided that the wind is slow (∼ sonic) at large distances from the Be star. Accepted by The Ast...
متن کاملAngular Momentum Transfer in the Binary X - ray Pulsar GX
We describe three presentations relating to the X-ray pulsar GX 1+4 at a workshop on magnetic fields and accretion at the Astrophysical Theory Centre, Australian National University on 1998, November 12-13. Optical and X-ray spectroscopy indicate that GX 1+4 is seen through a cloud of gravitationaly bound matter. We discuss an unstable negative feedback mechanism (originally proposed by Kotani ...
