A white dwarf, also called a degenerate dwarf, is a small star composed mostly of electron-degenerate matter. They are very dense; a white dwarf's mass is comparable to that of the Sun and its volume is comparable to that of the Earth. Its faint luminosity comes from the emission of stored thermal energy. In January 2009, the Research Consortium on Nearby Stars project counted eight white dwarfs among the hundred star systems nearest the Sun. The unusual faintness of white dwarfs was first recognized in 1910 by Henry Norris Russell, Edward Charles Pickering, and Williamina Fleming;^{, p. 1} the name white dwarf was coined by Willem Luyten in 1922.

White dwarfs are thought to be the final evolutionary state of all stars whose mass is not high enough to become a neutron star—over 97% of the stars in our galaxy.^{, §1.} After the hydrogen–fusing lifetime of a main-sequence star of low or medium mass ends, it will expand to a red giant which fuses helium to carbon and oxygen in its core by the triple-alpha process. If a red giant has insufficient mass to generate the core temperatures required to fuse carbon, around 1 billion K, an inert mass of carbon and oxygen will build up at its center. After shedding its outer layers to form a planetary nebula, it will leave behind this core, which forms the remnant white dwarf. Usually, therefore, white dwarfs are composed of carbon and oxygen. If the mass of the progenitor is above 8 solar masses but below 10.5 solar masses, the core temperature suffices to fuse carbon but not neon, in which case an oxygen-neon–magnesium white dwarf may be formed. Also, some helium white dwarfs appear to have been formed by mass loss in binary systems.

"A Whiter Shade of Pale" is the debut song by the British band Procol Harum, released 12 May 1967. The single reached number one in the UK Singles Chart on 8 June 1967, and stayed there for six weeks. Without much promotion, it reached #5 on the US charts, as well. It is one of the fewer than 30 all-time singles to have sold 10 million (or more) copies worldwide.^{[citation needed]}

With its haunting Bach-flavoured instrumental melody, soulful vocals, and unusual lyrics—by the song's co-authors Gary Brooker, Keith Reid, and Matthew Fisher-- "A Whiter Shade of Pale" reached #1 in several countries when released in 1967. In the years since, it has become an enduring classic. It was the most played song in the last 75 years in public places in the UK (as of 2009), and the United Kingdom performing rights group Phonographic Performance Limited in 2004 recognised it as the most-played record by British broadcasting of the past 70 years. Also in 2004, Rolling Stone placed "A Whiter Shade of Pale" #57 on its list of the 500 Greatest Songs of All Time.
