Summary
| Description |
English: The spectral power distribution of a typical A0V star (like e.g. Vega) from the HILIB stellar spectra library in comparison with a Planckian blackbody spectrum of the same effective temperature of 9500 K (dotted line) and visual color temperature of 15000 K (dashed line). Intensity B is in arbitrary units, and the curves are normalised to match at lambda = 555 nm. Both temperatures differ mainly due to the Balmer absoption bands in the ultraviolet region. This image has been inspired by figure 6.7 in the book "Der neue Kosmos" by A. Unsöld and B. Baschek, Springer Berlin, Heidelberg, New York, 6th edition 1999. ISBN 3-540-64165-3.
