solar physics

[′sō·lər ′fiz·iks]
The scientific study of all physical phenomena connected with the sun; it overlaps with geophysics in the consideration of solar-terrestrial relationships, such as the connection between solar activity and auroras.

Solar Physics


a branch of astrophysics that studies the physics of the sun. The use of spectroscopic, spectrometric, photometric, photographic, and radio astronomical methods of investigation make it possible to obtain information regarding the temperature, density, and velocities of the motion of matter in the sun’s atmosphere; the excitation and ionization of the atoms of chemical elements; the sun’s electric and magnetic fields; the position, dimensions, and structure of the sun’s active formations; and changes in these characteristics with time. Through the use of instruments carried up by rockets, studies are made of the solar radiation in the distant ultraviolet and X-ray regions of the spectrum as well as of the corpuscular radiation of the sun. By employing the methods of theoretical physics to interpret these data, it has been possible to construct a physical model of the entire sun and also of the separate active formations in its atmosphere.

The rate of decay of radioactive material on Earth may be affected by neutrinos emitted by the sun, according to ( a study published in the November edition of the journal Solar Physics. The controversial findings suggest that radioactive decay rates - long considered physical constants - may be more variable than previously thought.

Three scientists, David Hathaway (NASA/Marshall Space Flight Center), Giuliana de Toma (High Altitude Observatory), and Matthew Penn (National Solar Observatory) presented possible explanations of the Sun's odd behavior at July's meeting of the American Astronomical Society's Solar Physics Division in Bozeman, Montana.
The results are outlined in a paper soon to be published in the journal Solar Physics. Dr David Long, UCL Mullard Space Science Laboratory, and lead author of the research, said: "We've demonstrated that the Sun's atmosphere has a magnetic field about ten times weaker than a normal fridge magnet." Using data obtained using the Extreme ultraviolet Imaging Spectrometer (EIS), a UK-led instrument on the Japanese Hinode spacecraft, the team measured the density of the solar atmosphere through which the tsunami was travelling.
The findings are set to be published in the journal Solar Physics. ( ANI )
The solar physics workshops are jointly organized by the Advanced Technology Solar Telescope (ATST) and the European Association for Solar Telescopes (EAST) to bring together scientists, engineers, and especially the next generation of solar astronomers and instrument builders.
