MODELING FORMATION OF SELF-GRAVITATING DUST CONDENSATIONS A: Transcript


A B Makalkin I N Ziglina Schmidt Institute of Earth Physics Russian Academy of Sciences Obstacles to the growth of large dust particles and small bodies in a protoplanetary disk Metersized barrier. What force makes stars? . Gravity!. Out of what? Interstellar gas and dust. But this stuff is VERY low density… a dense area may have ~100 atoms / cm. 3. . Compare that the air you’re breathing… ~10. of dust heating in M81, M83 and NGC 2403 with Herschel and Spitzer. George J. . Bendo. Very Nearby Galaxies Survey . Goals. The overall goals of this research are to empirically identify the heating sources for the dust observed at 70-500 µm.. dust. . attenuation. and star formation histories . at. . high. . redshift. Véronique . Buat. Laboratoire d’Astrophysique de Marseille. Elbaz’s. lectures . (. david.elbaz3.free.fr/coursJ1.html), . Topic:. Gravoturbulent planetesimal formation. :. Particle clustering,. Streaming instability,. Particle trapping. Lecture by: C.P. Dullemond. Main idea:. If we can find a way to cluster the dust particles into small regions („dust clouds“) where the density of dust would be very large, then perhaps gravity could then take over and cause the dust cloud to gravitationally collapse (contract) to form a planetesimal.. planetesimal. -formation scenarios.
