DESCRIPTION:It has been known for many years that stars possess surface ma
 gnetic fields of considerable strength. Up to the present\, not only detai
 led characteristics of individual magnetic stars but also their statistica
 l properties have been revealed by observations. From a theoretical point 
 of view\, the importance of the magnetic effects on stellar evolution has 
 also long been noticed. In particular\, magnetic stress is regarded as the
  prime possibility for internal angular momentum transport. Despite the si
 gnificance\, however\, theoretical understanding of the evolution of the m
 agnetic stars has been limited. This is due to the difficulty of treating 
 stellar magnetic fields in a physically consistent manner\, and it is the 
 reason why we have been working on modeling magneto-rotational stellar evo
 lution. Recently\, we have proposed a new framework for stellar evolution 
 simulations in which the interplay between magnetic field\, rotation\, mas
 s loss\, and changes in the stellar density and temperature distributions 
 are treated self-consistently. In this talk\, I will present the essence o
 f the modeling and show the results of the first application to the 1.5 Ms
 un magneto-rotational evolution.
