... From the uvby photometry and proper motions for about 5500 nearby F stars we have found the following: (i) F stars , taken in narrow ranges of metallicity , show at [fe/H] 0 rather distinct cut-off in their distribution along the Main Sequence (MS) at the blue side, which is suggested to be an indication for the MS turn-off in stellar groups of fixed metallicity ; (ii) the corresponding turn-off age from theoretical isohrones strongly correlates with the ...

POROUS GRAINS IN THE SHELLS OF HERBIG Ae/Be STARS V.B. Il'in and N.A. Krivova Abstract.- We simulate the polarized radiation transfer in the shells with a spheroidal spatial distribution of fluffy dust grains. The circumstellar dust is represented by MRN mixture of silicate and graphite particles. The optical properties of porous grains are calculated using the EMT approximation and Mie theory. ... Effects of the porosity of grains on these data are considered. ...

In this section the program counts the integral for each region of the grid for each image. ... As a matter of fact, the integral is total brightness of the region and it is counted by 'int_tabulated' IDL function. ... In addition, the program will show the count of the regions which correlate with the corresponding region (the brighter region means the bigger count) and its contour. ...
