The loops of the Sun are deceptive

One of the Sun’s most amazing features is its radiant orbits – incandescent forms of hot plasma that glow for thousands of miles over the Sun’s magnetically active parts, acting like cords. curving.

But the features can be deceptive. Now, a group of modern physicists say these theaters may not have loopholes. But loops can be deceptive in a difficult way – magnetic paper or a sheet that can be pulled and twisted. The group calls this the coronal shield, and they believe that the glittering holes will be visible where the coronary artery is and more of our visual acuity.

Findings come from the search for simulations of the solar magnetic field published on March 2 i The Astrophysical Newspaper.

“I’ve spent my entire career studying coronal loops,” Malanushenko, a researcher at the National Center for Atmospheric Research in Boulder, Colorado, and lead author of the study, said in a statement. “I didn’t expect this. When I saw the results, my mind exploded. This is a completely new paradigm of understanding the atmosphere of the Sun.

Lifting the shield

For many years, scientists thought that coronal loops were what they were – the cords of hot plasma. Because particles with electric charge are in the plasma, their movement is stimulated by the Sun’s magnetic field. According to physicists, the plasma is the “happy” element in the magnetic field: The magnetic force guides the plasma along magnetic lines, the same lines that the metal images find around a magnetic field. . Therefore, it is not difficult to think of these glass windows as thin strands of ice-free plasma, following the curvature of the magnetic field.

However, there are some problems with the strands hypothesis in question. For one thing, high -altitude lines are more likely to fly away from their base – whether that base is a magnetic field or a group of sunspots. That is, if there are strings that are looking for lines of magnetic field, they must propel and be higher above the surface of the Sun. But that’s not what the observers say. “It’s okay for them to grow at a higher level but not as much as we expected,” Malanushenko said. Astronomy.

The other problem with the rope hypothesis is that the thickness of the Sun is less than its visible surface. That is, the nodes of the coronal loops are thinner and therefore do not have the same light as their bases. But they keep a different glow from top to bottom.
