Sun corona temperature in kelvin1/6/2024 Now, Shi and collaborators have applied AWSoM to a solar active region for the first time. AWSoM has been used to model a variety of solar phenomena, including predicting the conditions the Parker Solar Probe would experience on its first close approach to the Sun. The Alfvén Wave Solar Model (AWSoM) simulates heat transport by Alfvén waves - a type of plasma wave in which oscillating ions and magnetic fields pass energy back and forth. The color scale shows the strength and direction of the magnetic field in the radial direction in Gauss. The active region can be identified by the paired dark red and blue spots at a longitude of approximately 300. The team elected to model a solar active region that appeared on July 13, 2018. In a new publication led by Tong Shi (University of Michigan), a team of scientists has explored coronal heating by plasma waves with a high-resolution solar model. Undulating plasma waves that carry energy outward from the dense solar surface to the tenuous corona are one potential source of heating, but it’s unclear when or where this process might dominate over other heating methods. Solar physicists have identified a wide array of processes that could potentially heat the corona. The corona is the site of explosive solar activity like solar flares and coronal mass ejections, as well as the launching-off point for the diffuse solar wind that suffuses the solar system. Understanding how the Sun’s rarefied upper atmosphere, or corona, reaches its scorching million-kelvin temperature is one of the most important problems in solar physics. The Sun’s atmosphere gets progressively warmer with increasing distance from the core, from the photosphere at 6000K, to the chromosphere at 10000K, to the corona at 1 million kelvin. The temperatures of different layers of the Sun.
