Scientific paper

It is argued that there is a linear correlation between star formation rate (SFR) and accretion rate for normal bright active galactic nuclei (AGNs). We derive accretion rates for a sample of LINERs (with detected hard X-ray core, a type of LLAGNs) from their hard X-ray luminosities based on spectral calculations for radiatively inefficient accretion flows (RIAFs). We find that LINERs follow the same correlation between SFR and accretion rate defined by normal bright AGNs. It means that the gases feed the black hole and star formation in these low-luminosity LINERs may follow the same way as that in normal bright AGNs, which is roughly consistent with recent numerical simulations on quasar evolution.
