In previous research on dark matter stars, it has often been assumed that stars accreting dark matter will continue to grow until they become so dense that they collapse into black holes. However, in this new study, simulations showed that these stars actually appear to be stable and do not become black holes. Instead it may give rise to characteristic vibrations in stars.
This is the result of a paper recently published in Physical Review Letters, co-authored by Richard Brito, Vitor Cardoso from CENTRA, and Hirotada Okawa from Kyoto University and previous post-doc at CENTRA. The work was covered on Phys.org and in KIJK magazine (in Dutch).
