Título:Immediate dense circumstellar environment of supernova 
progenitors caused by wind acceleration.

Resumen: Density of circumstellar media at the immediate stellar 
vicinity can be high because of wind acceleration. We discuss the effect 
of such high density around red supergiants caused by the wind 
acceleration on Type II supernova properties. We find that early 
supernova light curves can be significantly affected by the dense 
circumstellar medium caused by the wind acceleration. Light curves with 
the dense circumstellar medium match to those of some observed Type II 
supernovae better. Our result indicates that the immediate dense 
environment of Type II supernova progenitors could be significantly 
influenced by wind acceleration.
