Altair (α Aquilae / α Aql / 53 Aql) es la estrella más brillante de la constelación de Aquila «El Águila». Los árabes, que también veían en esta constelación una gran águila volando, la llamaron elnars-el-tair, de donde derivó el nombre de Altair.
Ocupa el duodécimo lugar en orden de brillo entre todas las estrellas del cielo. Su magnitud en banda B (filtro azul) es 0,99, su magnitud en banda V (filtro verde) es 0,77. Está a 16 años luz del sistema solar, acercándose a razón de 26,1 m/s.
Es un astro magnífico, unas cuatro veces más voluminoso que nuestro Sol, de tipo espectral A (color blanco, igual que Sirio) y muchísimo más joven, con solo 630 millones de años de edad. La temperatura superficial de este tipo espectral oscila entre 7500 y 11 000 K, y el espectro presenta líneas intensas del hidrógeno, el calcio ionizado y otros metales ionizados, además de líneas débiles del helio.
Esta estrella, junto con Vega (α Lyrae) y Deneb (α Cygni), configuran en el cielo del hemisferio norte lo que se conoce como el triángulo de verano, cuyo centro es la estrella Albireo (β Cygni).
Altair posee una de las velocidades de rotación más altas que se conocen, solo inferior a las de las estrellas de neutrones y las enanas blancas. El periodo de rotación es solo de 6 horas 30 minutos y sus estratos periféricos ecuatoriales se mueven a la velocidad de 250 km/s. La rápida rotación axial de Altair se supone que está relacionada con la joven edad de la misma y resalta inmediatamente al examinar el espectro, cuyas líneas aparecen considerablemente ensanchadas debido al claro desfase en longitud de onda, de la radiación emitida por las partes de la estrella que se aproximan, con relación a la que proviene de las que se alejan. Debido a las grandes fuerzas centrífugas que se desarrollan en el interior de su propia masa, la estrella ha tomado forma achatada y su diámetro ecuatorial es un 20 % mayor que el polar.
Asimismo se verificó el fenómeno propio de estrellas de alta rotación conocido como «oscurecimiento gravitatorio».
Altair es una variable de tipo Delta Scuti y una doble óptica: tiene una compañera de magnitud +10 que, por el movimiento propio de Altair, se está alejando de ella; actualmente la separación ha alcanzado un valor de 165 segundos de arco.

Origin of the name Altair
The name Altair is of Arabic origin and means “flying” in translation.
But at the same time, the name comes from the name of the brightest star in the constellation Eagle, as well as the twelfth brightest, it can be seen with the naked eye. In addition to Arabic roots, the name Altair is associated with Greco-Latin culture, where it means “bird”.
Based on all this, the most accurate meaning of the name would be “flying eagle”, although it is often translated as “soaring falcon”, but the first version is more truthful, as it refers to a star in the constellation Eagle.
It is quite difficult to understand the origin of the name exactly. Altair is of Arabic origin, but it is rarely used by Arabs. The first half of the name is similar to English particles, and “tair” is translated as “bird”. Most likely, the name Altair refers to the pagan pre-Islamic tradition, because it is difficult to imagine a believing Mohammedan who would decide to call his son a bird. In Abrahamic religions, it is not customary to give divine significance to birds, and indeed to other animals in general.
