Radiatively inefficient accretion disks
H. C. Spruit
Radiatively inefficient (or advection dominated) disks are discussed at an introductory level. Ion supported and radiation supported flows are discussed, the different consequences…
Spirals and the size of the disk in EX Dra
V. Joergens, H. C. Spruit, R. G. M. Rutten
Observations at high spectral and temporal resolution are presented of the dwarf nova EX Dra in outburst. The disk seen in the He I line reconstructed by Doppler tomography shows a…
Theory of solar luminosity variations
H. C. Spruit
The theory of stellar structure can be used to identify the most plausible mechanisms for the irradiance variations associated with the solar cycle. Changes in surface emissivity,…
Jets from compact objects
H. C. Spruit
Some topics in the theory of jets are reviewed. These include jet precession, unconfined jets, the origin of knots, the internal shock model as a unifying theme from protostellar j…
