- In astronomy, stellar classification is the classification of stars based on their spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a prism or diffraction grating into a spectrum exhibiting the rainbow of colors interspersed with spectral lines. Each line indicates a particular chemical element or molecule, with the line strength indicating the abundance of that element. The strengths of the different spectral lines vary mainly due to the temperature of the photosphere, although in some cases there are true abundance differences. The spectral class of a star is a short code primarily summarizing the ionization state, giving an objective measure of the photosphere’s temperature.
- Beaux Arts Village — Thumbnail History (historylink.org)
Beaux Arts Village (King County) is a tiny rectangle of a town on the Eastside of Lake Washington, surrounded by its far bigger neighbor, Bellevue. In 1909 it got its start with plans to become an art colony, but that vision never came to pass. A pleasant community developed instead, which incorporated in 1954 to avoid being annexed by Bellevue. Though the village remained a mix of middle- and upper-class residents for much of its history, in recent years it has grown more affluent, with many of its homes now valued at more than $1 million.
