Accounting for light-element abundances
Article Abstract:
Michel Casse, Roland Lehoucq and Elisabeth Vangioni-Flam have discovered that light elements such as lithium, beryllium and boron in the solar system and interstellar medium are produced by the collision of cosmic ray particles with heavy elements ejected from the sun and stars. Their discovery resulted from the observation of gamma-ray lines from the sun and Orion nebula.

Discovery of two young brown dwarfs in an eclipsing binary system
Article Abstract:
The discovery of a brown-dwarf eclipsing binary system in the Orion Nebula star-forming region is reported from which direct measurements of mass and radius for newly formed brown dwarfs are obtained. Results reveal that large radii are generally consistent with theoretical predictions for young brown dwarfs in the earliest stages of gravitational contraction.
