英文摘要Type II supernovae represent the most common stellar explosions in the Universe, for which the final stage evolution of their hydrogen-rich massive progenitors towards core-collapse explosion are elusive. The recent explosion of SN 2023ixf in a very nearby galaxy, Messier 101, provides a rare opportunity to explore this longstanding issue. With the timely high-cadence flash spectra taken within 1-5 days after the explosion, we can put stringent constraints on the properties of the surrounding circumstellar material around this supernova. Based on the rapid fading of the narrow emission lines and luminosity/profile of H alpha emission at very early times, we estimate that the progenitor of SN 2023ixf lost material at a mass-loss rate M-center dot approximate to 6x10(-4)M(circle dot)a(-1) over the last 2-3 years before explosion. This close-by material, moving at a velocity v(w)approximate to 55kms(-1), accumulates a compact CSM shell at the radius smaller than 7x10(14) cm from the progenitor. Given the high mass-loss rate and relatively large wind velocity presented here, together with the pre-explosion observations made about two decades ago, the progenitor of SN 2023ixf could be a short-lived yellow hypergiant that evolved from a red supergiant shortly before the explosion.
