 Catalogs and Sources of Spectra

  • An Atlas of Stellar Spectra is a very detailed site with archived photographic plates of the spectral standard stars.
  • BASS2000 Solar Spectrum is a quereable database on the solar spectrum and related solar studies from the Paris Observatory. It also has links to live solar webcams in different wavebands.
  • SkyServer SDSS is the public and education site for the Sloan Digital Sky Survey. Data on over 88 million objects can be accessed online.
  • The 2dF Galaxy Redshift Survey provides access to over 250,000 galaxy spectra obtained in this survey.
  • WEBDA, a site devoted to open star clusters

Applets, Activities and Software

  • Absorption Spectroscopy uses Macromedia Shockwave in a web browser to simulate spectra from discharge tubes of different elements. You can produce different absorption lines and try and identify an unknown lamp.
  • Applet: Spectrum is a simple but effective Java applet that shows the frequency, wavelength and energy of any region of the em spectrum as you drag a mouse across it. It also shows sources of the different wavebands, how we detect them and some uses of each.
  • BlackBody Physlet is an effective Java applet that allows you to see the Planck curve and colour for stars of different temperatures.
  • black body Radiation Exercises: Planck Law Radiation Distributions is a Java applet that allows you to plot up to 10 Planck curves for temperatures from 3,000 to 30,000 K and compare them.
  • Elemental Spectra allows you to see absorption and emission spectra for every element as a photographic color spectrum.
  • Hydrogen Energy Levels is a simple applet demonstrating the use of the Bohr equation to calculate the energy levels of a hydrogen atom. It shows an energy level diagram vertically from infinity to the ground state.
  • Hydrogen Recombination Spectrum Applet simulates absorption of photons from a continuum source such as found in stellar atmospheres. Uisng hydrogen it shows the possible spectral lines that can form for different energy transitions.
  • HyperPhysics hydrogen energies and spectrum has a handy applet that calculates the wavelength for different transitions in hydrogen. The page also has useful energy level diagrams.
  • IMSA Astrophysics: Stellar Spectra and Planck black body Radiation is an excellent resource with detailed theory, clear diagrams and an Excel spreadsheet where you can model Planck curves and analyse data.
  • Mini Spectroscopy "is a simplified version of the Harvard-Smithsonian Center for Astrophysics full-featured spectroscopy software called Virtual Spectroscope."
  • Photon Emission Applet shows how photon transitions occur, how they are related to atomic energy levels and how the Balmer series for hydrogen can be produced.
  • Project CLEA The Classification of Stellar Spectra is an excellent free simulation for Win PCs.
  • Thermal Radiation Curves Applet allows you to specifiy a temperature or a peak wavelength for a star and view the corresponding Planck curve with a simulated visible spectrum superimposed on it.
