My Developing Research Interests

Hot Stars

The entire life cycles of hot massive stars, from their formation, through their trajectories across the Hertzsprung-Russell diagram, to their supernova explosions, and finally, to the compact objects that they leave, everything about hot stars and their environments interests me. Furthermore, it's my opinion, although I can't prove it, that big stars beget little stars. I'll simply point out that it is possible that the isotope ratios of the Solar System were fixed by a nearby supernova explosion shortly before our Sun's, and its planetary system's, birth. Hot stars and their environmental effects may not be nearly as remote from the issues surrounding the formation of our biosphere as we might think.

Binary Stars and Fundamental Stellar Parameters

Accurate and precise knowledge of the stars is better than approximate knowledge. From applying Kepler's Law to get masses, through using orbital parallaxes to find accurate stellar distances (far beyond the realm of measurable trigonometric parallaxes), to the use of interferometry, both speckle and optical long baseline , to find visual orbits (and inclinations), binary stars continue to be our primary source of accurate knowledge about the stars.

Spectroscopy and Spectrophotometry

From the blackbody curve to the curve of growth, whether using cross-correlation radial velocity techniques or deconvolving composite spectra with Doppler tomography ( Georgia State , St. Andrews University ), spectroscopy is where the absolute physical details are discovered.

My idea of a good way to get away from the daily hum-drum routine of Astronomy is to go out and do some ...
