Intrinsic brightness

WebExplain the importance of pulsating variable stars, such as cepheids and RR Lyrae-type stars, to our study of the universe. Let’s briefly review the key reasons that measuring distances to the stars is such a struggle. As discussed in The Brightness of Stars, our problem is that stars come in a bewildering variety of intrinsic luminosities.

WebThese stars are important because the period of a Cepheid depends on its intrinsic brightness, or absolute magnitude, in a known way: the brighter the star, the longer its period. All Cepheid variables with the same period have nearly the same intrinsic brightness, but their apparent brightnesses differ because they are at different distances.

WebAnswer (1 of 3): This is due to the fact that most stars that end their life in type of binary system are fairly similar. Usually there is a white dwarf in a binary orbit with a similar size dwarf or larger red star. As the white dwarf siphons the hydrogen shell that is … WebThese differences, depending upon the intrinsic brightness of the star, allow an estimate of its absolute magnitude, and the parallax can then be deduced by means of the equation (2) given above. This method has been applied to most of the brighter stars in the Northern Hemisphere, using stars of known parallax as standards.
