Searching for Axionlike Particles with X-Ray Observations of Alpha Centauri

Author(s): Yu-Xuan Chen, Lei Lei, Zi-Qing Xia, Ziwei Wang, Yue-Lin Sming Tsai, and Yi-Zhong Fan We investigate the production of axionlike particles (ALPs) in stellar cores, where they interact with electromagnetic fields and electrons, with typical masses between $\mathcal{O}(0.1)$ and $\mathcal{O}(10)\text{ }\text{ }\mathrm{keV}$. These low-energy ALPs are gravitationally trapped in the orbi… [Phys. Rev. Lett. 134, 241001] Published Tue Jun 17, 2025
