| Title: Forming Low Mass Stars and Brown Dwarfs in Protoplanetary Disks of Very Massive StarsAmit Kashi, Noam Soker - Quote :
- We suggest that planets, brown dwarfs, and even low mass stars can be formed
by fragmentation of protoplanetary disks around very massive stars (M>~100 solar masses). We discuss how fragmentation conditions make the formation of very massive planetary systems around very massive stars favorable. Such planetary systems are likely to be composed of brown dwarfs and low mass stars of ~ 0.1-0.3 solar masses, at orbital separations of ~ few 100 - 10^4 AU. Such fragmentation objects can be excellent targets for the James Webb Space Telescope and other large telescopes working in the IR bands. We predict that deep observations of very massive stars would reveal these fragmentation objects, orbiting in the same orbital plane in cases where there are more than one object.
