Kepler discovered the three stars is a mystery

Seen between the Kepler telescope, three-star beautiful dancing attracted the attention of astronomers because it is not accompanied by a song. Most stars are known to have a great in its internal booming sound and for Kepler the spot of light produced in them by the changes.
However, the astronomers report in Science that they have found the red giant is unexpectedly quiet.
HD181068A by two smaller orbital flight, the red dwarf star orbits the other.
Voice in the study of stars known as the astroseismology, and another report in the scientific details of the results of measurements of over 500 master rumors Kepler deep.
Because the process of moving the masses of stars up the core material of convection, a huge pressure wave - in essence, very low frequency sound waves - has been created.
As the gas compression and thin, the temperature change caused by light, to escape the star changes.
The voice of the star, and the clues they give to the stars make-up can be obtained from the "light curve" measures, such as the Kepler telescope, these small changes inferred.
Triple Play
  But HD181068 is an unusual situation - first, because it is a "triple-food" system. From Kepler's point of view, two smaller binary transmission, track each other in front of them, they passed in front of the red giant.
What happened just now on the system can calculate the star light is measured for each block of each stage of the three little waltz.
This is not the first system, the triple Kepler have found food, this is not the most popular Koi 126, also in February Report in.

  Stares and fixed in a patch corresponding to 1/400th of the sky Focus on the more than 150,000 stars In just four years, 1,235 candidate planets observed Where extrasolar planets have been found the first clear rock It has been found in 68 Earth-size planets, five in the "habitable zone" is Bill Borucki about Kepler But the silence of the red giant has confused the new study's lead author Aliz Derekas of Eotvos University in Hungary.
"This should beat the red giant," she told BBC News.
"We now know all of the red giant some oscillations - stellar surface should show some of the waves, should be light curve, we can estimate the oscillation period, which does not show the red giant time.."
The current best guess is that between the three stars in the gravitational work can help to combat HD181068 surface oscillation.
This is because the two smaller stars orbit every 0.9 days, while the other oscillator, the rumors from the red giant is expected, almost exactly half.
It may be stopped by the binary star on the surface of grabbing just the right time of the red giant oscillations.
Michael Montgomery, University of Texas at Austin astronomer, said another force may be at work.
"When you have a binary or ternary star, one of them burn all the hydrogen to become a red giant, if it is close enough that it can start to dump some of the material to other stars," he explained, BBC News.
"This is just circumstantial evidence, but perhaps its internal structure is not It would have been if it is a single star, which to some extent affect their ability to shock."
Either way, Kepler's fertility rate means that further examples of such systems may be just around the corner.
Montgomery, the doctor said: "These things are not as you think less, because we may find more of these systems, we will diagnose a year or two to sort this certainly.".
