6 FAQs about [Astrophysics solar power]

What is solar physics?

Solar physics is one of the liveliest branches of astrophysics at the current time, with many major advances that have been stimulated by observations from a series of space satellites and ground-based telescopes as well as theoretical models and sophisticated computational experiments.

What are some examples of solar physics?

In solar physics, existing paradigms include: 1. The solar corona is so hot that it can blow out against the solar gravitational field. 2. The solar wind is fully ionized plasma. 3. Sunspots appear when a magnetic flux tube breaks through the photosphere. 4.

What are some good books about solar physics?

Solar Physics, 170, 63–73. Eddy, J. A. (1976). The Maunder minimum. Science, 192, 1189–1202. Engvold, O., Skumanich, A., & Vial, J.-C. (2018). The Sun: a guide to stellar physics. Amsterdam, The Netherlands: Elsevier. Frazier, E. N. (1968). An observational study of the hydrodynamics of the lower solar photosphere.

How does solar physics differ from stellar physics?

In contrast to stellar physics, solar physics has been largely driven by the ability to resolve the features on the solar disk. In particular, high-resolution solar observations have made it possible to study the emergence and disappearance of solar magnetic fields directly as well as their sophisticated interaction with solar plasma.

What are the different aspects of solar activity?

A brief summary is given of the solar interior, helioseismology, the solar dynamo, the photosphere, the chromosphere, and the corona. There follows accounts of the different aspects of solar activity, namely, sunspots, the solar cycle, solar prominences, coronal mass ejections, and solar flares, as well as various aspects of the solar wind.

What is high energy solar activity?

The high-energy aspects of solar activity pervade the solar atmosphere and extended corona. Most prominently, these domains host transient events of many types, universally recognized to be episodic transfers of energy stored in the magnetic field into accelerated particles.
