StarFisher: Software Tool for Astronomical Spectral Data Analysis

Software tool for astronomers and astrophysicists to visualize and analyze spectral data from stars and galaxies, enabling interactive exploration and comparison of stellar spectra to determine properties like temperature, metallicity, and elemental abundances.

What is StarFisher?

StarFisher is an interactive software application designed specifically for astronomers and astrophysicists who work with spectral data from stars, galaxies, and other cosmic objects. It serves as a powerful tool for visualizing, analyzing, and understanding stellar and galactic spectra to reveal key details about their composition, physics, and evolution.

With an intuitive graphical user interface, StarFisher allows astrophysicists to import spectral data files in standard formats obtained from telescopes and archives. Its interactive plotting tools provide customizable visualization of spectral lines, with options to stack, compare, and overlay multiple spectra simultaneously. Users can seamlessly pan, zoom, and annotate plots to thoroughly inspect and interpret fine spectral features.

Going beyond visualization, StarFisher also enables detailed computational analysis. Its model fitting tools provide astrophysicists with quantitative derived properties by fitting synthetic spectral models — such as for temperature, metallicity, surface gravity, and individual elemental abundances — to the observed data. Models can be swapped, tweaked, and refit on-the-fly for in-depth, iterative analysis.

Additional key features of StarFisher include high-quality publication-ready plots with customizable multi-panel layouts, scripting and automation for batch processing, collaborative sessions for sharing insights across networks, and interoperability with Python for further custom analysis. With its combination of intuitive interactive graphics and rigorous quantitative tools, StarFisher aims to boost the productivity and discovery potential of spectroscopic astrophysics research workflows.
