Journal ArticleDOI
Active galactic nuclei as scaled-up Galactic black holes
TL;DR: In this article, it was shown that the accretion process is exactly the same for small and large black holes, provided that a correction is made to take account of variations in the rate of the process.
Journal ArticleDOI
The evolution of cataclysmic variables as revealed by their donor stars
TL;DR: In this paper, the authors reconstruct the complete evolutionary path followed by cataclysmic variables (CVs), based on the observed mass-radius relationship of their donor stars, using a semi-empirical CV donor sequence presented previously by one of us.

TL;DR: In this paper, the authors simulate IPHAS (r'-Halpha,r'-i') point-source colours using a spectrophotometric library of stellar spectra and available filter transmission profiles.
Journal ArticleDOI
The Donor Stars of Cataclysmic Variables
TL;DR: In this paper, a semi-empirical donor sequence for CVs with orbital periods less than 6 hours is presented. But the spectral types of the donor sequence are not directly compared to the observed SpTs.

TL;DR: The VST Photometric HSurvey of the Southern Galactic Plane and Bulge (VPHAS+) as mentioned in this paper is a survey of the southern Milky Way in u,g,r,i and h 1 arcsec angular resolution.
