AMHERST, Mass. – Using one of the most sensitive neutrino detectors on the planet, an international team of physicists including Andrea Pocar, Laura Cadonati and doctoral student Keith Otis at the Uni...
Constraints on dark matter models from a Fermi LAT search for high-energy cosmic-ray electrons from the Sun
Cosmic Rays Electrons Fermi Sun
2011/10/13
During its first year of data taking, the Large Area Telescope (LAT) onboard the Fermi Gamma-Ray Space Telescope has collected a large sample of high-energy cosmic-ray electrons and positrons (CREs). ...
Physics of the Sun’s Hot Atmosphere
Solar atmosphere X-ray EUV emission coronal heating solar wind
2010/9/16
This article briefly overviews the physics of the Sun’s hot atmosphere,using observations from recent solar spacecrafts: Yohkoh, SOHO,TRACE and RHESSI.
Why Study the Sun?
Sun—flares—prominences—coronal mass ejection—coronal holes—helioseismology
2010/9/16
In this presentation we briefly describe the Sun through large number of illustrations and pictures of the Sun taken from early times to the present day space missions. The importance of the study of ...
Physicists have so far failed to find direct evidence for the existence of dark matter – the non-luminous substance believed to make up some 23% of the mass-energy content of the universe – at least t...

The Sun's magnetic field environment astronauts
2010/9/21
The Sun's extended magnetic field provides a vital shield for astronauts; without it they would be left exposed to potentially deadly cosmic rays entering in from outside the solar system. Now, a grou...
On the Modelling of Rotational Effects in the Lower Convective Region of the Sun
Hydrodynamics-Sun general-Sun interior-Sun rotation-Sun fundamental parameters
2010/6/30
The purpose of this work is to study effects of differential rotation in the lower convective region of the Sun. Similar to MHD case; the governing equations are separated in variables, allowing numer...
The first high-resolution images of the Sun have been returned from NASA's Solar Dynamics Observatory (SDO), which was launched in February. The $850m mission will investigate the causes of solar vari...

MATHEMATICAL MODEL FOR THE 0.5 BILLION YEARS AGED SUN
MATHEMATICAL MODEL 0.5 BILLION YEARS AGED SUN
2009/3/16
An algorithm is given for constructing evolutionary tracks for a
star with the mass equal to one solar mass. The presented model can be applied
to the stars belonging to the inferior main sequence, ...
