So dense is the solar core that photons, the carriers of light, take millions of years to find their way to the surface.

I really felt like I was right in the middle of a solar core, and for one moment" She dropped her voice conspiratorially.

Because there is no convection in the solar core, the helium concentration builds up in that region without being distributed throughout the star.

It's got your normal dishdown center at solar core and a plane of the ecliptic that swoops upward from the center as you go out.

In effect, overall lower neutrino flux (which the Homestake experiment results found) required a reduction in the solar core temperature.

Gaseous matter with the temperature of a solar core bored through duranium hull plating and opened the small scoutship to the void.

Outside the solar core, where the overlying weight and compression are less, the gas is cooler and thinner, and nuclear fusion cannot take place.

Homestake Experiment (a contemporary experiment which detected neutrinos from nuclear fusion in the solar core)

The solar core cannot be imaged directly because electromagnetic radiation (such as light) is diffused by the great amount and density of matter surrounding the core.

But in this case, very minor, perhaps subatomic, variations in the solar core conditions caused the forces to escape Helion's control during one of his agitation runs.

The boy Q was a speck again, as he had been when Picard had first spied him across the immeasurably long radius of the solar core.

Gradually, the hydrogen burning in the shell around the solar core will increase the mass of the core until it reaches about 45% of the present solar mass.

She was, after all, Liana, a tawny, slender angel with long gunmetal black hair, and sultry jungle eyes that bored into a man's soul looking for his primeval solar core.

The successful detection of solar axions would constitute a major discovery in particle physics, and would also open up a brand new window on the astrophysics of the solar core.

The old theories had predicted dark-matter particles colliding with the swarming protons of the Solar core, absorbing a little of their energy and so transporting heat out from the fusing heart.

For me, my ambition was to do deeds never done nor dreamt before, to tame the titanic forces in the solar core to serve the use and pleasure of mankind, win glory for myself, and help civilization.

However, layers of the Sun are radiating to outer layers only slightly lower in temperature, and it is this difference in radiation powers between layers which determines net power production and transfer in the solar core.

Overall, the intense gravitation and radiation at the solar core were so tremendous that they practically overwhelmed his senses, and yet somehow he was still able to see Q, who looked rather bored until his eyes lit on something really interesting.

Within the Sun, the radiation zone is located in the intermediate zone between the solar core at .2 of the Sun's radius and the outer convection zone at .71 of the Sun's radius.

Whereas photons emitted from the solar core may require 40,000 years to diffuse to the outer layers of the Sun, neutrinos generated in stellar fusion reactions at the core cross this distance practically unimpeded at nearly the speed of light.

The next year, Bethe showed that this process is a key link in the proton-proton chain reaction and the CNO cycle, which are the major ways that nuclear energy is released in the solar core and in massive stars.

It was no more than a faint shadow against the flood of neutrinos from the Solar core, a vague coherence among scintillas of interaction with the slow-moving protons of the plasma... The shadow she'd seen had been a structure of dark matter.

The detection of g modes would be key to the understanding of the internal structure and dynamics of the solar core, as much as the p modes are key to that of the structure of the radiative and convective zones.

Richards bent over his duty station, and what had to be one of the most threatening spectroscopic analyses Uhura had ever seen exploded onto a viewscreen: perturbations deep within the solar core, building up until they erupted out from Loki into deadly prominences and hard radi- ation.

This so-called Mikheyev-Smirnov-Wolfenstein effect (MSW effect) is important to understand because many neutrinos emitted by fusion in the Sun pass through the dense matter in the solar core (where essentially all solar fusion takes place) on their way to detectors on Earth.
