Astronomer creates music of stellar pulsations

The oscillations of the star Y Cam A and the corresponding musical notes i>
Glitter any star is changing with time, but there is a separate class of variable stars whose brightness changes are periodic in nature, with gloss varies quite strongly. In 1958, the Soviet physicist Sergei Zhevakin constructed a theory of pulsations Cepheids - pulsating variable stars. They seem to "breathe": expand and contract with speeds reaching tens of kilometers per second. As if the music.
Not surprisingly, the astronomer Burak Ulashov (Burak Ulaş) and his colleagues from the College Planetarium Izmir Turk (Turkey) had the idea to put one of the stars twinkling in the real musical rhythm.
The scientific work describing the process of composing music published in the open access online arXiv.
For the experiment took Burak Ulashov star called Y Cam A. This is a double star, which causes its specific flicker. Instead of the usual flicker Y Cam A shows oscillations at four frequencies.
Astronomer musician used to compose the program Audacity. Pulsations of the lowest frequency he misappropriated note La. Other frequencies assigned it notes, which are often combined in chords of contemporary music: Salt, Re.
If you play these notes in the order in which flickers Y Cam A, and add a piano part, it turns out pretty good.

This is only one star. Astronomer making plans to make an orchestra of several stars that will be played by different instruments. Together, they play a real space opera. Burak Ulashov believes that this kind of music is perfect as a soundtrack for computer games and movies space subjects. And just amateur astronomers will listen to that, looking at the night sky.
