Albireo (Beta Cygni) is a beautiful double system in the constellation Cygnus that consists of a bright yellow star (Albireo Aa) and a slightly dimmer blue star companion (Albireo B) which together mark the beak of the celestial swan. There is an interesting rule about the colors of telescopic double stars. This lab will guide you to understand how to calculate the magnitudes of the stars from CCD images. The two components were listed as HD 183912 and HD 183913 in the Henry Draper Catalogue in 1923. Separated by 35 seconds of arc, the two components provide one of the best contrasting double stars in the sky due to their different colors. The 10 brightest stars in Cygnus are Deneb (Alpha Cyg, mag. The component magnitudes are 5.0 and 5.8 with a wide separation of 26 arcseconds. If you need the diameter of the star, you just need to multiple the radius by 2. All stars like planets orbit round a central spot, in the case of planets, its the central star such as the Sun. CCD Photometry in B and V of Vega and Albireo. 3.65 – 3.75), Iota2 Cygni (mag. The time it will take to travel to this star is dependent on how fast you are going. The star is 3.84 times more massive than the Sun and about 950 times more luminous. It has been known to produce widely incorrect figures. These red stars have the coolest temperatures among the stars in the cluster. The value comes from the Hipparcos Extended Catalog. The Radial Velocity, that is the speed at which the star is moving away/towards the Sun is -24.07000 km/s with an error of about 0.12 km/s . If the stars were to have the same speeds then we would know that they would be in orbit together, either one round the other or both round a central point in space. The Sun joins Albireo on January 21. It is a beautiful pairing of color-contrasting stars. Based on the spectral type (B8V) of the star, the star's colour is blue.
