Bayer Designation
A Bayer designation is a stellar designation in which a specific star is identified by a Greek or Latin letter followed by the genitive form of its parent constellation's Latin name. The original list of Bayer designations contained 1,564 stars. The brighter stars were assigned their first systematic names by the German astronomer Johann Bayer in 1603, in his star atlas ''Uranometria''. Bayer catalogued only a few stars too far south to be seen from Germany, but later astronomers (including Nicolas-Louis de Lacaille and Benjamin Apthorp Gould) supplemented Bayer's catalog with entries for southern constellations. Scheme Bayer assigned a lowercase Greek letter (alpha (α), beta (β), gamma (γ), etc.) or a Latin letter (A, b, c, etc.) to each star he catalogued, combined with the Latin name of the star's parent constellation in genitive (possessive) form. The constellation name is frequently abbreviated to a standard three-letter form. For example, Aldebaran in the constellation ...

Naming Conventions (technical Restrictions)
A naming convention is a convention (generally agreed scheme) for naming things. Conventions differ in their intents, which may include to: * Allow useful information to be deduced from the names based on regularities. For instance, in Manhattan, streets are consecutively numbered; with east–west streets called "Streets" and north–south streets called "Avenues". * Show relationships, and in most personal naming conventions * Ensure that each name is unique for same scope Use cases Well-chosen naming conventions aid the casual user in navigating and searching larger structures. Several areas where naming conventions are commonly used include: * In astronomy, planetary nomenclature * In classics, Roman naming conventions * In computer programming, identifier naming conventions * In computer networking, naming scheme * In humans, naming offspring * In industry, product naming conventions * In the sciences, systematic names for a variety of things Examples Examples of naming ...

HD 73634
HD 73634 is a single star in the southern constellation of Vela. It has the Bayer designation e Velorum; ''HD 73634'' is the star's designation from the '' Henry Draper Catalogue''. The star is white in hue and is faintly visible to the naked eye, having an apparent visual magnitude of +4.11. Parallax measurements provide a distance estimate of approximately 1,800 light years from the Sun. It is drifting further away with a radial velocity of +19 km/s. This evolved object has received stellar classifications of A7Ia and A6II, indicating that it is a massive supergiant or bright giant star. It has 7.8 times the mass of the Sun and is around 40 million years old. The star has expanded to nearly 34 times the girth of the Sun and is radiating around 4,140 times the Sun's luminosity from its enlarged photosphere at an effective temperature The effective temperature of a body such as a star or planet is the temperature of a black body that would emit the s ...

Bayer Objects
Bayer AG (, commonly pronounced ; ) is a German multinational pharmaceutical and biotechnology company and one of the largest pharmaceutical companies in the world. Headquartered in Leverkusen, Bayer's areas of business include pharmaceuticals; consumer healthcare products, agricultural chemicals, seeds and biotechnology products. The company is a component of the Euro Stoxx 50 stock market index. Bayer was founded in 1863 in Barmen as a partnership between dye salesman Friedrich Bayer and dyer Friedrich Weskott. As was common in this era, the company was established as a dyestuffs producer. The versatility of aniline chemistry led Bayer to expand their business into other areas, and in 1899 Bayer launched the compound acetylsalicylic acid under the trademarked name Aspirin. In 1904 Bayer received a trademark for the "Bayer Cross" logo, which was subsequently stamped onto each aspirin tablet, creating an iconic product that is still sold by Bayer.
