An asteroseismic constraint on the mass of the axion from the period drift of the pulsating DA white dwarf star L19-2
We employ an asteroseismic model of L19-2, a relatively massive M? ∼ 0.75M and hot (Teff ∼ 12 100 K) pulsating DA (H-rich atmosphere) white dwarf star (DAV or ZZ Ceti variable), and use the observed values of the temporal rates of period change of its dominant pulsation modes (Π ∼ 113 s and Π ∼ 19...
