Coronal Mass Ejections (CME)
Scientists tracking the continuous evolution of the energy state of the center of a solar outburst that occurred on July 20, 2017 have found that it strangely maintains a constant temperature.
- Coronal mass ejections (CMEs) are massive explosions of charged particles (plasma), and magnetic fields, from the solar atmosphere into space.
- They can disrupt ground stations on Earth and a range of space-based communication technologies and satellites.
Coronal Mass Ejections:
- Coronal mass ejections (CMEs) are massive eruptions of charged particles (plasma) and magnetic fields from the solar atmosphere into space. They can disrupt a range of geostationary and space-based technologies and satellites on Earth.
- The evolution of the thermodynamic properties of CMEs, such as temperature and density, is important for understanding their effects on Earth’s circulatory systems.
- There is a wide range of plasma temperatures within CMEs, from cold chromospheric material (about 104 K) to hot plasmas (about 107 K).
- CMEs can exchange energy (potential, electrical, kinetic, thermal, and so on) through a number of processes, which can heat or cool the plasma. Understanding CMEs will aid our ability to monitor space weather.
India’s Solar Mission:
The Visible Emission Line Coronagraph on Aditya-L1, India’s first solar mission, will perform both spectroscopy and imaging of CMEs in the inner corona, and provide new insights into the evolution of CME thermodynamic properties in the inner corona.
