| contents | We propose a novel method to detect axions which uniquely depends on the dimensionless axion-photon coupling $g_γ$, independent of the suppressive axion decay constant $f_a$. Using neutron star PSR B1919+21 data from the Five-hundred-meter Aperture Spherical Telescope, we derive the first constraint $|g_γ|<0.93$ at $1σ$ confidence level for ultra-light axions ($m_a < 10^{-11}$ eV). |
