Listen to a star's oscillations transformed into music
Burak Ulaş of the Izmir Turk College Planetarium in Turkey has created a duet between a piano player and a star called Y Cam A in the far reaches of our galaxy.
This is not the first time that we've heard stars sing. In 2014, the Rosetta comet was captured singing in the form of oscillations.
Ulaş created the composition by first delineating three categories, in the form of “three dimensionless transformation parameters (relative frequency, loudness, and starting time values) in order to generate a musical chord from the stellar oscillations.”
He then used the free music software Audacity to transform the star's waves into audible sounds and combined this with a recorded piano segment using Goldwave, a digital audio editor.

Ulaş noticed that the star's oscillations function similarly to the way chords function in music. The lights emanating from a star can indicate "a wave containing many sine like variations with certain frequencies and amplitudes.”
Ulaş hopes to continue to develop his compositions and plans to record a larger variety of instruments to create a more orchestral sound combined with star frequencies.
Facts about star vibrations:
The vibrations picked up from stars are caused by a phenomenon called "starquakes," which are seismic waves rippling through a star, causing it to emit light.
In 2004, a starquake released more energy than the sun emits in 150,000 years in just a tenth of a second.
