SUMMARY:The electromagnetic weight loss of compact axion stars - Liina Chu
 ng-Jukko\, King’s College London

DESCRIPTION:If dark matter is composed of axions\, then axion stars are ex
 pected to be abundant in the Universe. In this talk\, I will demonstrate i
 n fully non-linear (3+1) numerical relativity the instability of compact a
 xion stars due to the electromagnetic Chern-Simons term. The coupling of t
 he axion to electromagnetism forms the basis of various axion detection ex
 periments. I will show that above a critical coupling constant\, compact a
 xion stars are unstable\, decaying into a less massive\, less compact\, re
 mnant. Finally\, I’ll address this instability in the context of axion s
 tar mergers.
