초록

Proof correction to the equation in the third paragraph of the DISCUSSION AND CONCLUSION has not been carried faithfully to the published version of the paper. The corrected equation should read ≈ 10 -3 M 8 4/3(N*/10 6 pc-3)(σ/300 km s-l)-l(r/rt) yr-1, where Ms is the mass of the SMBH in units of 10 8 M⊙, σ is the virial velocity of the stars, rt is the tidal radius of the SMBH. This estimates the frequency that a star would pass within a sphere with the radius r from the SMBH, rather than the frequency of the tidal disruption event. Therefore, it increases with the mass of the SMBH. However, the loss cone effect should also be taken into account, which reduces the actual event rate. Here, we adopted a factor of one hundred to consider the deficiency from the isotrophic rate. The authors sincerely regret this error.
