The Discovery and Characterization of an Ultracompact Hot Subdwarf and Brown Dwarf Binary System
Stellar binary systems are astronomical objects made of two stars gravitationally bound to each other. In some of these systems, the stars are so close that they interact with each other and affect the formation and evolution of one another. As a result, understanding these objects can provide …

The binary system containing the pulsar PSR 1913+16 and ultra-violet and x-radiation from accreting magnetic white dwarfs
"Part I of the thesis deals with the binary system containing the pulsar PSR 1913+16. The system has been touted as a laboratory for testing relativistic theories of gravity, and is also. a challenge for theories of stellar evolution. However, proposed uses of the system rely on assumptions about …

A structural study of lyotropic liquid crystal phases formed by aqueous solutions of fluorinated surfactants
The binary lyotropic liquid crystalline system Caesium Perfluorooctanoate (CsPFO) / heavy water ( 2H20) has previously been reported to exhibit three mesogenic phases. These were, as a function of decreasing temperature at fixed concentration and pressure isotropic, nematic and lamellar. The …
