Description:
Polaris and Dust around the Pole Star The Integrated Flux Nebula (IFN) Integrated Flux Nebula (IFN) can be seen around the galaxies. This faint glow is caused by the combined light of the stars of the Milky Way reflected and re-emitted by interestellar gas and dust. Polaris is a Cepheid stars, stars that have evolved off the main sequence into the Cepheid instability strip. They are regular radial-pulsating stars, with a well-defined period-luminosity relationship, which makes them ideal stars to be used as primary distance indicating standard candles. The surface of Cepheid Polaris slowly pulsates, causing the star to change its brightness by a few percent over the course of a few days.
