چکیده
|
The present article is dedicated to demonstrate a new statistical distance scale. the new scale is based on: (1) the correlation between the ionized mass and the radius of planetary nebulae; (2) the correlation between the radio surface temperature and the radius of planetary nebulae. the new distance scale is verified by determination of the distance of galactic center and the expected distribution of galactic bulge planetary nebulae. the new statistical distance scale is applied to determine the statistical distances for 650 planetary nebulae. the results are compared with the distances determined from other alternative distance scales.
