The sun is a ball of gas—a special kind of gas to be sure. It is so hot in some regions in the interior that the atoms have come apart completely to form a state of matter known as a plasma—an electrically charged gas. To understand the physical processes that cause stars, like ...
The sun is made ofgas and plasma. Most of the gas — 92% — is hydrogen. If the sun were smaller, it would just be a huge ball of hydrogen akin toJupiter. According to NASA Space Place, the hydrogen in the sun's core is held together by a lot ofgravityresulting in high pressure...
The plasma gas is introduced intoPROBLEM TO BE SOLVED: To simply, highly efficiently and stably perform desulfurizing treatment to extra-low sulfur concentration without using an LF apparatus and a vacuum degassing apparatus whose facility cost and treatment cost are high and without exerting an ...
In fusion, two atomic nuclei are combined to create a heavier nucleus, and the process releases energy. The reaction takes place in a state of matter called plasma, which is distinct from liquids, solids or gasses. In the sun, nuclei collide at hot enough temperatures to overcome the electri...
For decades we have known that the Sun lies within the Local Bubble, a cavity of low-density, high-temperature plasma surrounded by a shell of cold, neutral gas and dust1,2,3. However, the precise shape and extent of this shell4,5, the impetus and timescale for its formation6,7, an...
"The Sun's corona, or extended outer layer, is a region of plasma that is heated to over a megakelvin. As a result of thermal collisions, the particles within the inner corona have a range and distribution of speeds described by a Maxwellian distribution. The mean velocity of these partic...
Starfishis a 2D (Cartesian or axisymmetric) code for simulating a wide range of plasma and gas problems. It implements the electrostatic Particle-in-Cell (ES-PIC) method along with several fluid solvers. Material interactions are included through MCC or DSMC collisions, or via chemical reactions....
The solar wind is composed of plasma that is released by the Sun. The plasma is made up of very hot ionized particles of hydrogen and helium gas. How does solar wind affect Earth? Solar wind can interact with Earth's magnetic fields and excite the electrons in the gases found in the at...
Sputtering is a process that uses gaseous plasma to dislodge atoms from the surface of a solid target material. The atoms are deposited to form an extremely thin coating on the surface of the substrates. It is a technique often used to deposit thin films of semiconductors, CDs, disk drives,...
The surface of the sun is electrically active and it is completely covered by the photosphere. The sun's surface rotates uniformly every 27.3 days unlike the plasma layer of the photosphere.
