I will be leading Graham School educational trips to these eclipses. For information, click here. Many people have requested information about the innovative way I have been teaching introductory astronomy in the Common Core. An article about that is now on line here . My research interests include stellar spectroscopy, testing the Big Bang by studying abundances in the oldest stars, galactic chemical evolution, stellar rotation, and the evolution of stars like the sun.
Recent papers are on line.
The Hubble Space has been used to obtain spectra of the boron 2500 Ang. The observed relation suggests that the production of light elements such as B and Be is directly related to the production of heavier elements. Our data do not show a change in slope between halo and disk metallicities, but the number of stars near the disk-halo transition is small and a modest change is not precluded. Especially during the Galaxy's early history, when the metallicity of the ISM was low, the spallation of protons and alpha particles onto CNO nuclei cannot account for as much B as we observe unless the CR flux was sufficiently higher to compensate. It is possible that the gamma rays recently detected from the Orion Nebula region are the signature of spallation by energetic C and O nuclei.
