Solar Eruptions Cause Sunquakes

April 2, 2012 1 comment

A study led by UCL’s Mullard Space Science Laboratory has shown for the first time that sunquakes can be produced during eruptions of magnetic field and charged particles, as the immense magnetic structure blasts off into the Solar System. The results will be presented by Dr Sergei Zharkov at the National Astronomy Meeting 2012 in Manchester on Friday 30th March 2012.

The first observation of a sunquake was reported by Kosovichev & Zharkova in the late 1990s. During the last decade it has become well established that explosions in the Sun’s atmosphere, known as solar flares, can create sunquakes through the impact of powerful beams of particles which travel into the Sun. This new study shows that eruptions of material known as coronal mass ejections are also able to produce sunquakes.
