Variability of L_bol(t) and M_BLRs(t) in the TDE ASASSN-14li. Top panel: MOSFIT-determined time-dependent bolometric luminosity L_bol(t) = ηṀ_a(t)c² (solid blue line) and the corresponding confidence bands (dashed blue lines) in ASASSN-14li. Solid circles plus error bars in red show the scaled L_Hα(t)×k_cl with k_cl = 5000, open circles plus error bars in dark green and in purple show the corresponding results with k_cl = 14 000 and k_cl = 7500 applied to the observed L_Hβ(t) and L_He(t) in ASASSN-14li. Bottom panel: Determined M_BLRs(t) (solid blue line) applied to describe the L_Hα(t)=k_BLRs × M_BLRs(t) in ASASSN-14li, with dashed blue lines for the determined confidence bands after accepting the uncertainties of the M_BLRs, 0. Solid circles plus error bars in red show the scaled L_Hα(t)/k_BLR with k_BLRs = 8.25 × 10⁴² erg/s/M_⊙, open circles plus error bars in dark green and in purple show the corresponding results with k_BLRs = 2.94 × 10⁴² erg/s/M_⊙ and k_BLRs = 5.50 × 10⁴² erg/s/M_⊙ applied to the observed L_Hβ(t) and L_He(t) in ASASSN-14li.
