Next: The Chemical Evolution of Up: Stellar Astrophysics Previous: Stellar Astrophysics . Simon Jeffery has used a novel camera attached to the William Herschel Telescope (WHT) to obtain the best light curves ever obtained for pulsating subdwarf B stars. These stars pulsate non-radially in several modes with different frequencies and enable astronomers to establish their overall properties and internal structure with unusual precision. ...

... The most precisely determined characteristic for accreting neutron stars (NS's) is their period. ... Period changes show fluctuations. ... Some applications of stochastic processes in astrophysics especially in accreting systems were discussed in Lipunov (1987),Hoshino Takeshima (1993) and Lipunov (1992).In Hoshino Takeshima (1993) the authors, using simple models of MHD turbulence, try to explain aperiodic changes in X-ray luminosity of X-ray pulsars. ... Here, -constant angular momentum. ...

... Data Analysis SAS News What is SAS? ... The accuracy of the energy cross-calibration of the EPIC-pn camera in different operating modes was determined, using observations of the line-rich supernova remnant (SNR) Cas-A. For the Extended Full Frame (eFF) mode a special energy calibration was performed, which showed an overcorrection of the energy with respect to the Full Frame (FF) mode for the internal calibration source at aluminium and manganese energies. ...
