Vega vs Torreon

Informations

Vega is the brightest star in the northern constellation of Lyra. It has the Bayer designation α Lyrae, which is Latinised to Alpha Lyrae and abbreviated Alpha Lyr or α Lyr. This star is relatively close at only 25 light-years from the Sun, and, together with Arcturus and Sirius, one of the most luminous stars in the Sun's neighborhood. It is the fifth-brightest star in the night sky, and the second-brightest star in the northern celestial hemisphere, after Arcturus. Vega has been extensively studied by astronomers, leading it to be termed "arguably the next most important star in the sky after the Sun". Vega was the northern pole star around 12,000 BC and will be so again around the year 13,727, when its declination will be +86° 14′. Vega was the first star other than the Sun to be photographed and the first to have its spectrum recorded. It was one of the first stars whose distance was estimated through parallax measurements. Vega has functioned as the baseline for calibrating the photometric brightness scale and was one of the stars used to define the zero point for the UBV photometric system.

Vega is only about a tenth of the age of the Sun, but since it is 2.1 times as massive, its expected lifetime is also one tenth of that of the Sun; both stars are at present approaching the midpoint of their life expectancies. Vega has an unusually low abundance of the elements with a higher atomic number than that of helium. Vega is also a variable star that varies slightly in brightness. It is rotating rapidly with a velocity of 236 km/s at the equator. This causes the equator to bulge outward due to centrifugal effects, and, as a result, there is a variation of temperature across the star's photosphere that reaches a maximum at the poles. From Earth, Vega is observed from the direction of one of these poles.Based on an observed excess emission of infrared radiation, Vega appears to have a circumstellar disk of dust. This dust is likely to be the result of collisions between objects in an orbiting debris disk, which is analogous to the Kuiper belt in the Solar System. Stars that display an infrared excess due to dust emission are termed Vega-like stars.

Torreón (Spanish pronunciation: [toreˈon] (listen)) is a city and seat of Torreón Municipality in the Mexican state of Coahuila. As of 2015, the city's population was 679,288. The metropolitan population as of 2015 was 1,497,734, making it the ninth-biggest metropolitan area in the country and the largest metropolitan area in the state of Coahuila, as well as one of Mexico's most important economic and industrial centers. The cities of Torreón, Gómez Palacio, Lerdo, Matamoros, Francisco I. Madero, San Pedro, Bermejillo, and Tlahualilo form the area of La Laguna or the Comarca Lagunera, a basin within the Chihuahuan Desert. The area was originally a center for ranching.

With irrigation, the city became an important center for farming and the processing of cotton. In the middle of the 20th century, it became an industrial city. The city has industries in textiles, clothing and metals processing. Some important industries and companies have business here, like Peñoles, Motores John Deere, Grupo Lala, Yura Corporation, as well as stores like Soriana, Cimaco, and Extra. There are also several shopping malls in the city, including Galerias Laguna, Almanara, Plaza Cuatro Caminos, and InterMall. Torreón is served by Francisco Sarabia International Airport, an airport with flights to several cities in Mexico and the United States.
