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. ...

... Identification and Analysis of Binary Star Systems using Probability Theory E. Grocheva and A. Kiselev Photographic Astrometry Department, Pulkovo Observatory, S.Petersburg, 196140, Russia, Email: gl@spb.iomail.lek.ru Abstract. Accurate identification of physical binary star systems has become of increasing interest in recent years. ... We chose 76 double stars from Pulkovo's observation program and calculated the probabilities of a random distribution for these pairs. ...

... The dynamics of silicate and graphite particles with radii of (0.1-2) 10 -5 cm in the vicinity of the Milky Way is considered. The equation of motion of dust grains is integrated with gravitational attraction, radiation pressure, gas drag, and dust destruction taken into account. The effect of other factors on the motion of grains are discussed. ... Dust is swept out of the Galaxy by radiation pressure from stars at a rate of 0.04 M o yr -1 . ...

... The circumnuclear GASEOUS disks are often decoupled from the circumnuclear stellar disks and are even stronger inclined to the outer disk planes; in fact, we have found a considerable `population' of inner polar rings. Inner gas polar rings are found as in spiral galaxies with the massive outer gas disks co-planar to the main symmetry planes (e.g. NGC 2841, Sil'chenko et al. 1997, and NGC 7217, Sil'chenko & Afanasiev 2000) as well in many lenticular galaxies (Fig. ...

. A distribution list is very useful where a group of users need to communicate amongst themselves on a regular basis. Each list is given a name just like any other user. By addressing a message to the list name, the sender can be sure that everyone will receive a copy. You cannot set up a distribution list yourself. Ask your system administrator to set one up for you.
