Title: Signatures of Mirror Stars

Abstract: Motivated by theories of neutral naturalness, I will argue that Mirror Stars 
are a generic possibility in any hidden sector with analogues of Standard Model 
electromagnetism and nuclear physics. I will show that if there exists a tiny kinetic 
mixing between the dark and SM photon, Mirror Stars capture SM matter from the 
interstellar medium, which accumulates in the Mirror Star core. This leads to a 
spectacular and distinctive signature that could be discovered in optical and X-ray
