On the isotropy of viscosity in accretion discs
Chris Nixon, Jim Pringle
Accretion discs are fundamental to many astrophysical systems, providing the conversion of gravitational potential energy into radiation that we can observe. In many systems there…

The Morphology of Asteroidal Dust Around White Dwarf Stars: Optical and Near-infrared Pulsations in G29-38
T. von Hippel, J. Farihi, J. L. Provencal +20
More than 36 years have passed since the discovery of the infrared excess from circumstellar dust orbiting the white dwarf G29-38, which at 17.5 pc it is the nearest and brightest…

On the role of numerical diffusivity in MHD simulations of global accretion disc dynamos
C. J. Nixon, C. C. T. Pringle, J. E. Pringle
Observations, mainly of outbursts in dwarf novae, imply that the anomalous viscosity in highly ionized accretion discs is magnetic in origin, and requires that the plasma …
