Stellar Evolution and Axion-Like Particles: New Constraints and Hints from Globular Clusters in the GAIA DR3 Data

Troitsky, S. V.

Axion-like particles (ALPs) are hypothetical pseudoscalar bosons, natural in extensions of the Standard Model. Their interactions with ordinary matter and radiation are suppressed, making it challenging to detect them in laboratory experiments. However, these particles, produced within stellar interiors, can provide an additional mechanism for ene…
