COSMOGRID is an Irish project to develop and exploit e-science technology for research in cosmic physics. Under this scheme, Simon Jeffery leads a project to develop tools for the automated analysis of stellar spectra. During 2003, Christopher Winter and Gustavo Dopcke were engaged on this project. In the case of low-resolution spectra, we use a neural network to classify and parameterise a given set of observations. Preliminary results were presented at conferences during 2003. We have also developed fitting software to measure precise chemical abundances from stellar spectra, using our state-of-the-art stellar atmosphere modelling software. Ultimately, we aim to offer a tool to astronomers world-wide so that, using a computing grid, remote users can obtain a detailed analysis of their latest spectrum `online'. Some of the prototype JAVA interfaces necessary to carry out these analyses interactively were developed during the year.
