英文摘要It has been argued that there is a linear correlation between star formation rate (SFR) and accretion rate for normal bright active galactic nuclei (AGNs). However, it is still unclear whether this correlation holds for LINERs, the accretion rates of which are relatively low compared to those of normal bright AGNs. Radiatively inefficient accretion flows (RIAFs) are believed to be present in these LINERs. In this work, we derive accretion rates for a sample of LINERs from their hard X-ray luminosities, based on spectral calculations for RIAFs. We find that LINERs follow the same correlation between SFR and accretion rate defined by normal bright AGNs when reasonable parameters are adopted for RIAFs. This means that the gases feeding black hole and star formation in these low-luminosity LINERs may follow the same pattern as those in normal bright AGNs, which is roughly consistent with recent numerical simulations on quasar evolution.
