The findings, published in The Astrophysical Journal, reveal new details about the star's size, appearance, and characteristics. Polaris, a Cepheid variable star, is the brightest member of a ...

Using this, astronomers only needed to know the period of a cepheid variable to figure out how bright, and therefore how far away it was. Until then, methods for measuring distances in space only ...

The star, a so-called Cepheid variable, which lies in the constellation of Gemini, expands and contracts every 10 days but, like most stars, is far too small to be seen in conventional telescopes. To ...

Astronomers in the US have succeeded in observing changes in the diameter of a Cepheid variable star for the first time. Measurements of Cepheids are important because they restrict the range of ...
