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 ...

V337 Carinae
V337 Carinae (V337 Car, q Carinae) is a K-type bright giant star in the constellation of Carina. It is an irregular variable and has an apparent visual magnitude which varies between 3.36 and 3.44. V337 has a spectral class of K2.5II, indicating a bright giant. It is considered likely to be on the red giant branch of stars fusing hydrogen around an inert helium core. Its limb-darkened angular diameter has been measured using interferometry Interferometry is a technique which uses the ''interference'' of superimposed waves to extract information. Interferometry typically uses electromagnetic waves and is an important investigative technique in the fields of astronomy, fiber opt ... at . V337 Carinae has two companions listed in multiple star catalogues. Both are 13th-magnitude stars, component B and component C away. Component B is a distant background star, while component C is at about the same distance as V337 Carinae. References ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HD 61248
HD 61248 is a single star in the southern constellation of Carina. It has the Bayer designation Q Carinae, while ''HD 61248'' is the star's identifier in the '' Henry Draper Catalogue''. This star has an orange hue and is visible to the naked eye with an apparent visual magnitude of 4.93. Based upon parallax measurements, it is located approximately 402 light years in distance from the Sun. The object is drifting further away with a radial velocity of +63 km/s, having come to within some 1.8 million years ago. This is an aging giant star with a stellar classification of K3 III, which means it is no longer undergoing core hydrogen fusion. It has expanded to 30 times the Sun's radius and is radiating 279 times the luminosity of the Sun 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 same total amount of electromagnetic r ...

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.
