Vectron International, a leader in the design and manufacture of precision oscillators and timing solutions for communication, industrial, military & space applications, announces its new VC-826 differential XO in a 3225 (3.2 x 2.5 mm) package.
Astronomers using the new Atacama Large Millimeter/submillimeter Array (ALMA) have imaged a region around a young star where dust particles can grow by clumping together. This is the first time that such a dust trap has been clearly observed and modelled. It solves a long-standing mystery about how dust particles in discs grow to larger sizes so that they can eventually form comets, planets and other rocky bodies. The results are published in the journal Science on 7 June 2013.
