© 2011 PhysOrg.com The two suggest that on occasion some big stars move close enough to binaries (paired stars) that they get pulled into their gravitational field, resulting in an unbalanced state as the trio moves awkwardly through space. After some time passes, the big star gets the boot and as a result of the buildup of energy created between the three, is sent hurtling out into space, becoming a runaway star.Such stars have been the focus of much attention as they travel so much faster than all the other stars around them. Most in the Milky Way Galaxy by contrast plod along at a measly five kilometers per second, so it’s not difficult to see why the speedsters would draw so much attention. Prior to this research, some suggested the big stars got their speed from being near another star that exploded. Other’s theorized that they’d maybe simply paired with another star and the two began moving around one another at a faster clip, similar to ball room dancers. Though in this case, the two would have wound up flinging one another apart in opposite directions in their grand finale.To back up their theory, Fujii and Zwart built a computer simulation of star clusters and found that over time each cluster did indeed include binaries that attracted other stars that were eventually sent packing by the original two. The researchers believe this proves that the majority, if not all runaway stars became such due to being rejected as a temporary third mate for binaries.This new thinking came about when two stars last year were spotted speeding away from a dense group of star clusters believed to be less than two million years old, which seemed to fly in the face of the exploding partner idea, as such stars aren’t thought to explode until reaching at least three million years of age.At any rate, as time passes, it should be easy enough to prove this new theory; all scientists have to do is trace back the trajectories of speeding stars to see if they came from identifiable binaries.

Now however, astrophysicists Michiko S. Fujii and Simon Portegies Zwart describe in their paper published in Science, how they believe that the big stars get their speed as a result of being hurled out and away from binary star couplings that occur within the centers of clusters of stars.

An ardent lover of music, Rukmini Devi invited several great musicians to Kalakshetra, and together, they composed and produced over thirty dance dramas based on traditional forms. It is to her credit that, sixty years later, they have retained their freshness and beauty. The Kalakshetra productions are today recognized for their in-depth research, impeccable technique and refined aesthetics. The most significant of these is the famous ‘Ramayana’ series. In 1955, Rukmini produced the first of the Ramayana dance-dramas – Sita Swayamvaram, with the music composed by the legendary Sri Vasudevacharya of Mysore. Rukmini Devi based her production largely on Valmiki’s classical version, which runs into 24,000 stanzas. She completed the Ramayana series – six in all – in 1969, 14 years after she began the venture.Besides this, the classic play ‘Waiting For Godot’ featuring Naseeruddin Shah was also performed on 15 November.
