Cooperative operations between a photo voltaic statement satellite tv for pc and a sounding-rocket telescope have measured the magnetic area energy within the photosphere and chromosphere above an lively photo voltaic plage area. That is the primary time that the magnetic area within the chromosphere has been charted all the best way up its prime. This discovering brings us nearer to understanding how power is transferred between layers of the Solar.


Regardless of being the brightest object within the sky, the Solar nonetheless holds many mysteries for astronomers. It’s typically believed that magnetic fields play an essential function in heating the , however the particulars of the method are nonetheless unclear. To unravel this thriller you will need to perceive the magnetic area within the chromosphere, which is sandwiched between the corona and the photosphere, the seen floor of the Solar.

A global staff led by Ryohko Ishikawa, an assistant professor on the Nationwide Astronomical Observatory of Japan, and Javier Trujillo Bueno, a professor on the Instituto de Astrofísica de Canarias, analyzed knowledge collected by the CLASP2 sounding rocket experiment over six-and-a-half-minutes on April 11, 2019. They decided the longitudinal part of the magnetic area above an lively area plage and its environment by analyzing the signature that the magnetic area imprinted on ultraviolet mild from the chromosphere.

The distinctive excessive precision knowledge from CLASP2 allowed the staff to find out the magnetic area strengths within the decrease, mid, and higher areas of the chromosphere. Concurrently acquired knowledge from the Japanese photo voltaic statement satellite tv for pc Hinode offered details about the magnetic area within the plage itself within the photosphere. The staff discovered that the plage is extremely structured within the however expands, quickly merging and spreading horizontally, within the . This new image brings us nearer to understanding how magnetic fields switch power to the corona from the decrease layers of the Solar.
