Do Neutron Stars Gleam Within Dark Matter?
Oct 27, 2026 · 21m
Summary
This episode explores the strong CP problem and the potential existence of axions, hypothesizing that magnetars act as efficient cosmic factories for these elusive particles. The discussion details how plasma simulations reveal that neutron stars can generate axions despite natural suppression mechanisms, potentially explaining mysterious phenomena like pulsar radio jets and fast radio bursts. While these stars cannot account for all dark matter, their axion clouds offer new avenues for detection through future radio astronomy observations.
