Turbulence and wave particle interactions in solar-terrestrial plasmas [PDF]
Theoretical modelling of two dimensional compressible convection in the Sun shows that convective flows can extend over many pressure scale heights without the nonlinear motions becoming supersonic, and that compressional work arising from pressure ...

Further observations of the lambda 10830 He line in stars and their significance as a measure of stellar activity [PDF]
Measurements of the lambda 1030 He line in 198 stars are given along with data on other features in that spectral range. Nearly 80% of all G and K stars show some lambda 10830; of these, half are variable and 1/4 show emission.

The nautre of dwarf novae and related systems [PDF]
The high energy emissions from cataclysmic variables (interacting binary systems containing an accreting white dwarf) and the relationship of the high energy emission of these stars to their optical properties were investigated.
