We have performed spherically symmetric, time-dependent hydrodynamical calculations for the X-ray emitting gas around elliptical galaxies, NGC4472, for the purpose to reproduce profiles of temperature and density. Stellar mass loss rate and type Ia supernova rate are assumed to be constant. Thermal conduction is introduced to stabilize against thermal instability due to radiative cooling.
