Title: How AGN and star formation connect: Eigenvector I as an \"AGE\" indecator of AGN 
Authors: J. Wang; J. Y. Wei & X. T. He

Abstract: The Eigenvector I(EI) space is first extended into IR-color $\\alpha(60,25)$ 
and [OIII]/H\\beta_n by performing a PCA on an IR-color selected Seyfert 1.5s sample.  
Our EI is truned to be dominated by $\\alpha(60,25)$ and strongly affected by RF, 
[OIII]/H\\beta_n and EW(H\\beta_b), which indicates the E1 space is most likely 
related to the nuclear SF history. In addition to confirm the work of Xu et al. (2003), 
we find the Seyferts with both large RFe and [OIII]/H\\beta_n are rare. As an case study, 
a spectacular post-starburst NLS1 SDSSJ085338.27+033246.1 is detailed examined. 
A simple 0.1Gyr SSP suggests the <SFR>~70 M_o/yr which is extremely larger than 
the current SFR~3 M_o/yr. A possible evolutionary scenario is proposed.
