WebDec 5, 2024 · One of these puzzles involves the Sun's tachocline, a belt of heat transition. “A tachocline is when the radiative interior of a star rotates like a solid ball, but the … WebOct 7, 2016 · The omega effect is understood to originate in the tachocline - the narrow band between the Sun's inner radiative zone and the outer areas. In the tachocline, lots of different rotating areas converge, and researchers suspect that this generates two magnetic belts situated north and south of the solar equator.

WebMar 3, 2016 · Rotational shear layers at the boundary between radiative and convective zones, tachoclines, play a key role in the process of magnetic field generation in solar-like stars. We present two sets of global simulations of … WebApr 19, 2011 · This is despite the kinematic viscosity being somewhat greater than χ. We discuss how the confinement layers s at each pole might fit into a global dynamical picture of the solar tachocline. That picture, in turn, suggests a new insight into the early Sun and into the longstanding enigma of solar lithium depletion.
WebFrom 0.3 to 1.2 solar masses, the region around the stellar core is a radiation zone, separated from the overlying convection zone by the tachocline. The radius of the radiative zone increases monotonically with mass, with stars around 1.2 solar masses being almost entirely radiative. Webthe dark lines and bands in the solar visible continuous spectrum are due to: 1. no emission at these wave lengths 2. absorption in the solar atmosphere 6 in the UV, on the sun we see: 1. active regions 2. magnetic loops 3. flares 4. coronal holes 5. …
