video: Evolution of the density structure (white contour) around the accreting protostar. During the accretion phase, a bi-polar ionized atomic hydrogen region appeared temporally (red contour) due to the increasing intensity of the stellar UV radiation but accretion bursts weakened the radiative feedback. The protostellar continued growing steadily up to 34,000 solar-masses. This material relates to a paper that appeared in the 29 September 2017, issue of Science, published by AAAS. The paper, by S. Hirano at University of Texas, Austin in Austin, TX, and colleagues was titled, "Supersonic gas streams enhance the formation of massive black holes in the early universe." view more
