Star Reg
How do I calculate the radius of the stars (red giants VAT) from Abs.Magnitude, Color Index and the Spectrum?
I have seen some letters but I'm working with a relatively large database and need to be able to calculate these values quickly. The result has to be precise in everything, but should look on the right to look at the pictures. Reg giants are more difficult to solve? Please specify the radio units (Solar or miles, etc.), if applicable.
1. Derive an surface temperature, whether the color index or spectral type. 2. Using the Stefan-Boltzmann law (http://en.wikipedia.org/wiki/Stefan-Boltzmann_law) to calculate luminous flux. 3. Determine the total power output of the absolute magnitude, and use that with the luminous flux to calculate the size of the star. These sites should help conversion factors: http://www http://spiff.rit.edu/classes/phys301/lectures/absolute/absolute.html http://www.astronomynotes.com/starprop/s4.htm. go.ednet.ns.ca / ~ / Larry Astro / HR_diag.html time you work outside of the constants is required, you should be able to make a spreadsheet or script for fast processing data.
