Next: Jets Up: M.D. Smith Previous: High-Mass Star Formation Contents . By contrast, stars of low mass like our Sun are formed within molecular clumps. Michael Smith has been investigating the clumps and the individual cores they contain within one nearby cloud near the star Rho Ophiuchi. With Stanke (Hawaii), Khanzadyan (Heidelberg) and Gredel (Calar Alto), he has determined the masses of over 100 protostellar cores and compared this to the distribution of masses for stars. ...

. Produced by the Sloan Digital Sky Survey, this 3-D map of the distribution of galaxies shows Earth at the center, and represents each galaxy with a single point . Large astronomical surveys, such as SDSS, rely upon a model of Baryon Acoustic Oscillations to provide a cosmological тАЬstandard rulerтАЭ for determining length scale. Ohio State UniversityтАЩs Chris Orban and David Weinberg have employed Ohio Supercomputer Center resources to simplify and better characterize that BAO model. M. Blanton and SDSS
