Our understanding of the structuring of the magnetic field in the photosphere (Solanki, 1999) has provided the background to explain some of the energetic processes that take place in higher. ![]() Jennifer Ouellette, Wired, 18 June 2021 Coronal mass ejections are the largest, connecting the photosphere to the corona, where reconnection can cause an enormous release of energy.Įthan Siegel, Forbes, 8 June 2021 That friendly yellow photosphere boils like oatmeal and is pocked with dark magnetic storms (the infamous sunspots) that crackle, whirl and lash space with showers of electrical particles and radiation. The photosphere is the portion of the atmosphere where we are able to measure with some confidence the magnetic field that pervades the Sun outer layers. According to Kirchhoff, the sun's photosphere is either solid or liquid, and is surrounded by an extensive atmosphere, composed of gases and vapors of the substances incandescent in the photosphere. Jennifer Ouellette, Wired, 18 June 2021 The findings last year showed that an outer layer of the star, called the photosphere, had begun unevenly accelerating outward right before Betelgeuse began to dim.

Jennifer Ouellette, Ars Technica, 12 Aug. 2022 The resulting shocks and pulsations were powerful enough to produce an SME, blasting a massive chunk of the star's photosphere into space. Euler angles can be defined in many ways. 2022 The shocks and pulsations blasted off a chunk of the photosphere, leaving a cool surface area under a cloud of dust. The orientation of the photo sphere in the world frame is defined by Euler angles. Recent Examples on the Web The piece of Betelgeuse’s photosphere, which weighed several times as much as the moon, was released into space.Īshley Strickland, CNN, 12 Aug. ![]()
