Abstract：
With the aim of exploring the fast evolutionary path from the blue cloud of star-forming galaxies to the red sequence of quiescent galaxies in the local universe, we select a local advanced merging infrared luminous and ultraluminous galaxy (adv-merger (U)LIRGs) sample and perform careful dust extinction corrections to investigate their positions in the SFR-$M_{/ast}$, u-r and NUV-r color-mass diagrams. The sample consists of 89 (U)LIRGs at the late merger stage, obtained from cross-correlating the IRAS Point Source Catalog Redshift Survey and 1 Jy ULIRGs samples with the Sloan Digital Sky Survey DR7 database. Our results show that 74% pm 5% of adv-merger (U)LIRGs are localized above the 1 sigma line of the local star-forming galaxy mainsequence. We also find that all adv-merger (U)LIRGs are more massive than, and as blue as the blue cloud galaxies after corrections of Galactic and internal dust extinctions, with 95% pm 2% of them outside the blue cloud on the u-r color-mass diagrams. The identification of obscured transiting post-starbursts following Yesuf et al. and an analysis for the distributions of EW(Halpha) and D_n(4000) values on the NUV-r color-mass diagram show that some adv-merger (U)LIRGs are already at the initial stage of fading way. The timescale for exhausting the molecular gas reservoir in adv-merger (U)LIRGs is 3*10^{7} to 3*10^{8} years. Thus, our results support the fast evolutionary mode proposed by several groups. While the number density of adv-merger (U)LIRGs is only ～0.1% of the blue cloud star-forming galaxies in the local universe, this evolutionary track may play a more important role at high redshift.
