audio: This audio file mimics what accresion systems might sound like. The idea is that as all accreting systems display 'flickering' variability in their observed lightcurve, which can be translated into an audio wave. For big systems like supermassive black holes and young stellar objects, the "sounds" will be lower in pitch when compared to smaller systems like galactic black holes. This is file number 1 out of 5. This material relates to a paper that appeared in the Oct. 9, 2015, issue of Science, published by AAAS. The paper, by S. Scaringi at Max-Planck-Institut für Extraterrestriche Physik in Garching, Germany, and colleagues was titled, 'Accretion-induced variability links young stellar objects, white dwarfs, and black holes.' view more
