Spectral energy distributions (SEDs) show the amount of energy emitted by an object as a function of wavelength. SEDs are not the same thing as blackbodies! But stars can be approximated by blackbodies, so blackbodies come up a lot in the context of SEDs. This page covers concepts; there is another page on how to make SEDs.
Most coherent, developed, tested materials
- Movie (12:46) on Temperatures and Blackbodies, part of the "Filters, Magnitudes, Colors, Oh My!" playlist -- Dr. Luisa Rebull, 2020
- Movie (0:30, soundless) that shows blackbodies as a function of temperature (T) -- Dr. Luisa Rebull, 2017
- Movie (0.31, soundless) that shows a blackbody with varying reddening (Av) -- Dr. Luisa Rebull, 2017
Somewhat less coherent (or less standalone) materials
- SED plots introduction -- Dr. Luisa Rebull (2012-2013)
- The influence of reddening -- Dr. Luisa Rebull (2012)
