Orbital periods and Accretion disc structure of four AMCVn systems
Phase-resolved spectroscopy of four AMCVn systems obtained with the William Herschel Telescope and the Gran Telescopio de Canarias (GTC) is presented. SDSS J120841.96+355025.2 was found to have an orbital period of 52.96±0.40min and shows the presence of a second bright spot in the accretion disc. The average spectrum contains strong Mg i and Si i/ii absorption lines most likely originating in ...
متن کاملPotentials of Evolving Linear Models in Tracking Control Design for Nonlinear Variable Structure Systems
Evolving models have found applications in many real world systems. In this paper, potentials of the Evolving Linear Models (ELMs) in tracking control design for nonlinear variable structure systems are introduced. At first, an ELM is introduced as a dynamic single input, single output (SISO) linear model whose parameters as well as dynamic orders of input and output signals can change through ...
متن کاملThe Evolving Accretion Disc in the Black Hole X-ray Transient XTE J1859+226⋆
We present HST, RXTE, and UKIRT observations of the broad band spectra of the black hole X-ray transient XTE J1859+226 during the decline from its 1999–2000 outburst. Our UV spectra define the 2175 Å interstellar absorption feature very well and based on its strength we estimate E(B − V ) = 0.58 ± 0.12. Hence we deredden our spectra and follow the evolution of the spectral energy distribution o...
متن کاملDisc-overflow Accretion in Intermediate Polars
We have recently realised that intermediate polars accrete in a range of modes. While accretion is predominantly through an accretion disc, in some systems the accretion stream overrows the disc and interacts with the magnetic eld directly. In RX 1712{24, discless accretion dominates. I review the current status of these observations, concentrating on the information from the X-ray lightcurves.
متن کاملMagnetic activity in accretion disc boundary layers
We use three dimensional magnetohydrodynamic simulations to study the structure of the boundary layer between an accretion disc and a non-rotating, unmagnetized star. Under the assumption that cooling is efficient, we obtain a narrow but highly variable transition region in which the radial velocity is only a small fraction of the sound speed. A large fraction of the energy dissipation occurs i...
