Resumen:
Accretion disks are observed in association with a variety of astrophysical objects, ranging from binary systems to active galactic nuclei. A very efficient energy conversion process is believed to take place in accretion disks, transforming gravitational energy into kinetic and thermal energy of the plasma, and typically convertingthem into X-ray sources. Within the general framework of hydrodynamics and magnetohydrodynamics, we present the basic features required to perform a theoretical description of the process of accretion for a number of cases of astrophysical interest.
