Alpha, originally known as Alpha AXP, is a 64-bit reduced instruction set computing (RISC) instruction set developed by Digital Equipment Corporation (DEC), designed to replace their 32-bit VAX complex instruction set computer (CISC) instruction set. Alpha was implemented in microprocessors originally developed and fabricated by DEC. These microprocessors were most prominently used in a variety of DEC workstations and servers, which eventually formed the basis for almost all of their mid-to-upper-scale lineup. Several third-party vendors also produced Alpha systems, including PC form factor motherboards.

Operating systems that supported Alpha included OpenVMS (previously known as OpenVMS AXP), Tru64 UNIX (previously known as DEC OSF/1 AXP and Digital UNIX), Windows NT (using a 32-bit emulation layer and discontinued after 4.0 SP6 and Windows 2000 RC1),Linux (Debian GNU/Linux, SUSE Linux,Gentoo Linux and Red Hat Linux), BSD UNIX (NetBSD, OpenBSD and FreeBSD up to 6.x), Plan 9 from Bell Labs, as well as the L4Ka::Pistachio kernel.

American singer Selena has released five studio albums, three live albums, one soundtrack and twenty-one compilation albums. Credited for elevating a music genre into the mainstream market, Selena remains the best-selling Tejano recording artist whose posthumous releases continue to outsell those of living musicians. As of 2015, the singer has sold 60 million copies worldwide, and was named the "Top Latin Artist of the '90s" and "Best-selling Latin Artist of the Decade" by Billboard magazine. In 1995, Selena was inducted into the Billboard Latin Music Hall of Fame, the Hard Rock Cafe's Hall of Fame, the South Texas Music Hall of Fame, and the Tejano Music Hall of Fame in 2001.

Selena's career began as lead vocalist of Los Dinos in 1980. She signed with EMI Latin nine years later as a solo artist though her band continued to tour with her. She released her self-titled debut album that same year, which peaked at number seven on the U.S. Billboard Regional Mexican Albums chart. With Selena, the singer outsold other female Tejano artists. She released her second album Ven Conmigo in October 1990; it peaked at number three on the Regional Mexican Albums chart. Ven Conmigo was later certified gold by the Recording Industry Association of America (RIAA) for shipments of 50,000 units, the first recording by a female Tejano artist to do so. As of 2010, Ven Conmigo had sold 500,000 copies in the United States. According to music critics, her next recording Entre a Mi Mundo (1992), was the "breakthrough album" of her musical career. The album and its lead single, "Como la Flor", helped launch the singer's career in Mexico.Entre a Mi Mundo peaked at number one on the Regional Mexican Albums chart for eight consecutive months; and was certified 6× platinum by the RIAA, signifying shipments of 600,000 units. Entre a Mi Mundo became the first Tejano recording by a female artist to sell over 300,000 copies.

This is a list of Foundation universe planets featured or mentioned in the Robot series, Empire series, and Foundation series created by Isaac Asimov.

61 Cygni

The star system 61 Cygni, in the Sirius Sector, is advanced by Lord Dorwin as the potential site for a planet of origin for the human species. Lord Dorwin cites 'Sol' (meaning Earth's Sun) and three other planetary systems in the Sirius Sector, along with Arcturus in the Arcturus Sector, as potential original worlds. (This fact seems to be contradicted by information given in Foundation and Earth). Claims were made as early as 1942 that 61 Cygni had a planetary system, though to date, none has been verified, and Asimov was aware of these claims.

Alpha

Alpha is a fictional planet orbiting the larger of the two stars in the Alpha Centauri system.

In Asimov's Foundation Series, Alpha Centauri is cited by Lord Dorwin as one of the solar systems where humankind potentially originated. The others are Sol, Sirius, 61 Cygni and Arcturus. Beyond mentioning that it is in the Sirius Sector, Dorwin gives no further details.
