How Planets Are Built
Scientists interested in the origin of Earth and the other planets study regions where new solar systems are forming. The planet-building process is occur-ring throughout the Milky Way galaxy in much the same way as it did about 4.6 billion years ago, when our sun and its planets formed. Logan Brown will explain how astronomers observe young stars, still surrounded by the remnants of the huge clouds of dust and gas from which they condensed. They search within the disk-shaped structures of protostars for traces of water and other chemicals necessary for life. Of particular interest to Mr. Brown is the problem of how planets such as the Earth obtained their water and other volatiles.
Logan Brown is a Doctoral candidate in the Department of Physics and Astronomy of UMSL. A native of southeastern Wisconsin, he has come to UMSL to study planetary system formation and early evolution. His research is focused on the chemistry of protoplanetary disks of dust and gas.
