Scientists tune into music of stars from M4 galaxy
Q. Scientists have tuned into the music of the stars detecting resonant acoustic oscillations in which galaxy?- Published on 08 Jun 16a. M2
b. M3
c. M4
d. M5
ANSWER: M4
Scientists have assessed the music of the stars. Ancient stars in the Milky way were found to display minute pulses in brightness caused by sound captured inside
- Astrophysicists from the University of Birmingham captured these sounds, according to research published today in the Royal Astronomical Society journal Monthly Notices.
- The research team, from the University of Birmingham's School of Physics and Astronomy, has reported the detection of resonant acoustic oscillations of stars in 'M4', one of the oldest known clusters of stars in the Galaxy, some 13 billion years old.
- They studied resonant oscillations of stars using a technique called asteroseismology.
- These oscillations lead to miniscule changes or pulses in brightness, and are caused by sound trapped inside the stars. By measuring the tones in this 'stellar music', it is possible to determine the mass and age of individual stars.
