Discovery of a New Torque Reversal of the Accreting X-ray Pulsar 4U 1626-67 by Fermi/GBM
A. Camero-Arranz, M. H. Finger, N. R. Ikhsanov +2
Recent X-ray observations by Fermi/GBM discovered a new torque reversal of 4U 1626-67 after 18 years of steady spinning down. Using Swift/BAT observations we were able to center th…
Spin-Down of the Long-Period Accreting Pulsar 4U 2206+54
Mark H. Finger, Nazar R. Ikhsanov, Colleen A. Wilson-Hodge +1
4U 2206+54 is a high mass X-ray binary which has been suspected to contain a neutron star accreting from the wind of its companion BD +53 2790. Reig et al. have recently detected 5…
New Torque Reversal and Spin-Up of 4u 1626- 67 Observed by Fermi/GBM and Swift/BAT
A. Camero-Arranz, M. H. Finger, N. R. Ikhsanov +2
After about 18 years of steadily spinning down, the accretion-powered pulsar 4U 1626-67, experienced a torque reversal at the beginning of 2008. For the present study we have used…
