英文摘要	We present a detailed analysis of the progenitor and its local environment for the recently discovered Type II supernova (SN) 2024ggi at a distance of about 6.7 Mpc, by utilizing the pre-explosion images from the Hubble Space Telescope and Spitzer Space Telescope. The progenitor is identified as a red bright variable star, with absolute F814W-band magnitudes being -6.2 mag in 1995 to -7.2 mag in 2003, respectively, consistent with that of a normal red supergiant star. Combining with the historical mid-infrared light curves, a pulsational period of about 379 days can be inferred for the progenitor star. Fitting its spectral energy distribution with stellar spectral models yields the stellar parameters of temperature, radius, and bolometric luminosity as T=3290(-27)(+19) K, R=887(-51)(+60) R-circle dot, and log(L/L-circle dot) =4.92(-0.04)(+0.05 ), respectively. The above parameters indicate that the progenitor of SN 2024ggi is consistent with the stellar evolutionary track of a solar-metallicity massive star with an initial mass of 13(-1)(+1) M-circle dot. Moreover, our analysis indicates a relatively low mass-loss rate (i.e., <3 x 10-6 M-circle dot yr(-1)) for the progenitor compared to that inferred from flash spectroscopy and X-ray detection (i.e., 10(-2)-10(-5) M-circle dot yr(-1)), implying a significant enhancement in mass loss within a few years prior to the explosion.
