Welcome to our Spectral Energy Distributions (SEDs) page with educational tools including templates and instructions for investigating SEDs. This project is made possible through NASA/IPAC Teacher Archive Research Project (NITARP) here.
What are SEDs?
A spectral energy distribution is a graph of the energy emitted by a star as a function of wavelength. An SED resembles a blackbody curve, and can be composed of spectra or photometric data observations of a star.
Why SEDs?
Key items used in studying stars are spectral type, temperature, radius and distance. These terms may be defined for students, but understanding how astronomers use data to determine these items is not as obvious. This page will help students understand, determine, and learn how to apply information about spectral type, temperature, radius and distance to answer deeper questions, such as cluster membership.
