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). ...
Enhanced Sensitivity to Dark Matter Self-annihilations in the Sun using Neutrino Spectral Information
Dark Matter, Solar WIMPs, WIMP-nucleon scattering cross section, Neutrino Astronomy
2011/10/10
Self-annihilating dark matter gravitationally captured by the Sun could yield observable neutrino signals at current and next generation neutrino detectors. By exploiting such signals, neutrino detect...
Mass Loss, Destruction and Detection of Sun-grazing and -impacting Cometary Nuclei
comet sun impact sun-grazing radiation collisions
2011/9/30
Incoming sun-grazing comets almost never re-emerge, but no final destruction event has ever been observed, nor sun-impactor destruction theory developed. We seek analytic models of comet nucleus destr...
Measuring the Earth-Sun distance during a lunar eclipse
Measuring Earth-Sun distance lunar eclipse
2011/9/28
The classical method for measure the Earth-Sun distance is due to Aristarchus and it is based upon the measure of the angle Moon-Earth-Sun when the Moon is exactly in quadrature. Such an angle is only...
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 ...
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...

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, ...
