Scientists discover new way of determining strong magnetic fields under stars
Q. Scientists have discovered a way to determine magnetic fields inside massive giant stars by using a technique associated with ______________.- Published on 26 Oct 15a. Medical Ultrasound
b. Asteroseismology
c. Both of the above
d. None of the above
ANSWER: Both of the above
Scientists have for the first time developed a means to determine presence of strong magnetic fields inside pulsating giant stars through a technique associated with medical ultrasound. Magnetic fields have important consequences in all phases of stellar evolution from the formation of the star to its demise. Researchers have used asteroseismology similar to seismology for tracking waves travelling through stars to determine inner properties. Technique uses sound waves to image invisible parts of the human body.
