  Title: X-RAY STUDY OF EARLY TYPE GALAXIES WITH LOW VELOCITY DISPERSIONS AND LOW BLUE LUMINOSITIES


Abstract:
 We have found that the thermal energy per unit mass of the hot gas in early type
 galaxies is greater than the stellar thermal energy per unit mass. The excess gas
 temperature increases as the stellar velocity dispersion decreases, which suggests
 that there may be additional mechanisms to the gravitational heating. This heating
 mechanisms may not be stellar origin like supernova explosions. To reveal this
 mechanisms, we propose the observations of early type galaxies which have low
 velocity dispersions and low blue band luminosities.
