Astrophysicists for the first time provide an explanation for observed relationships among the structure and supersonic internal motions of molecular clouds, where stars form, known as Larson’s Laws. The paper, titled ‘A Supersonic Turbulence Origin of Larson’s Laws’, was published in the Monthly Notices of the Royal Astronomical Society.
The researchers based their analysis on recent observational measurements and data from six simulations of the interstellar medium, including effects of self-gravity, turbulence, magnetic field, and multiphase thermodynamics. The supercomputer simulations support a turbulent interpretation of Larson’s relations, and the study concludes that there are not three independent Larson laws, but that all three correlations are due to the same underlying physics, i.e. the properties of supersonic turbulence.

At just 16 years of age, Eric Chen began working with chemistry professor Rommie Amaro on a more effective way of developing drugs to treat the flu virus. He has just been awarded the grand prize in the Google Science Fair. His project, “The Taming of the Flu,” was chosen in the competition open to students ages 13 to 18 from 120 countries worldwide.
