AI Article Synopsis
- Macroscopic dark matter in the "asteroidlike" mass range can interact with baryonic matter, potentially producing detectable emissions.
- When these dark matter objects pass through stars, they generate shock waves that create transient emissions in optical, UV, and x-ray wavelengths.
- Observing these emissions in dense globular clusters can significantly enhance our understanding of dark matter, with a current UV telescope capable of conducting effective measurements in just a week.
Article Abstract
Macroscopic dark matter is almost unconstrained over a wide "asteroidlike" mass range, where it could scatter on baryonic matter with geometric cross section. We show that when such an object travels through a star, it produces shock waves that reach the stellar surface, leading to a distinctive transient optical, UV, and x-ray emission. This signature can be searched for on a variety of stellar types and locations. In a dense globular cluster, such events occur far more often than flare backgrounds, and an existing UV telescope could probe orders of magnitude in dark matter mass in one week of dedicated observation.
