Flux Density Variations Of PKS 1830–211

A High Torque Density Axial Flux SRM with Modular Stator

A novel structure of switched reluctance motors (SRMs) is proposed. The proposed structure uses the benefits of the axial flux path, short flux path, segmental rotor, and flux reversal free stator motors all together to improve the torque density of the SRMs. The main geometrical, electrical and physical specifications are presented. In addition, some features of the proposed structure are comp...

The Magnetar Xte J1810–197: Variations in Torque, Radio Flux Density and Pulse Profile Morphology

We report on observations of the radio-emitting anomalous X-ray pulsar XTE J1810–197 during 2006 May– October using the Nançay, Parkes, GBT, and VLA telescopes at a frequency of 1.4 GHz. The torque experienced by the neutron star during this period, as inferred from a measurement of its rotational frequency derivative, decreased by 30%, although not in a steady manner. We have also observed ver...
