scientists claim sun is fractionally smaller than we thought
Scientists Masao Takata of Tokyo University and Douglas Gough of Cambridge said that millions of sound waves are produced inside the Sun. These include P-waves, G-mode and F-mode. The seismic radius of the Sun is usually measured through F-mode. Although scientists do not trust them much. Instead, p-modes travel much longer distances in the Sun's plasma.
The research paper states that the 'F mode' frequency analysis has yielded a new measurement of the Sun's radius, which is a few hundred percent less than the optical measurement. Both scientists also argue that P-mode should be used to measure the Sun's radius.
Talking about other news related to the Sun, we set out to study the biggest star of our solar system 'Sun'.
ISRO's Aditya L-1 spacecraft has recently sensed a 'mega-explosion' there. Aditya L-1 has seen the first high energy X-ray glimpse of solar flares. In a post recently, ISRO said that the 'High Energy L1 Orbiting X-ray Spectrometer' (HEL1OS) installed in the 'Aditya L1' spacecraft has recorded the solar flare.
