Theoretical research concerns the physics of accreting compact objects such as cataclysmic variables, x-ray binaries, and active galactic nuclei; observational tests of such theories are also performed.

The problems studied include (1) radiation transfer in optically thin gas such as quasar emission line clouds and in optically thick gas such as x-ray illuminated stellar atmospheres and accretion disks; (2) accumulation of a high-quality atomic physics data base for use in spectral modeling; (3) gas dynamics such as accretion flows in x-ray binaries and stellar winds; and (4) construction of synthetic x-ray, ultraviolet, and optical spectra of accreting objects and detailed comparison with observational data.

Applicants are encouraged to participate in any of these areas or to initiate related research.
