Customer ServiceSolar System models, especially mechanical models, called orreries, that illustrate the relative positions and motions of the planets and moons in the Solar System have been built for centuries. While they often showed relative sizes, these models were usually not built to scale. The enormous ratio of interplanetary distances to planetary diameters makes constructing a scale
Customer ServiceThis model contains real data and real orbital math; but distances and differences in space and time are algorithmically reduced to make the exploration experience more interesting and fun. Other aspects of the solar system (those that do not make the experience less fun) are modeled quite accurately.
Customer ServiceThis 3D model of the Sun shows five of six layers. From the center out, the three large interior layers of the Sun are (1) the core, (2) the radiative zone, and (3) the convective zone. The outer visible layers are (4) the photosphere, (5) the chromosphere, and (6) the outermost layer, the corona, which extends outward for more than 12 solar radii. In this model the corona is not
Customer ServiceThe standard solar model serves two purposes: (1) it provides estimates for the helium abundance and mixing length parameter in the Sun by forcing the solar model to have the correct luminosity and radius at the Sun''s age, and (2) it provides a laboratory to test new physics and compare "improved" solar models which have additional physics

Customer ServiceThe Standard Solar Model predicts that the sun consists of a core that is surrounded by three layers. These layers include the radiative layer, the convective layer, and the photosphere. The sun''s core has half of the sun''s mass. That means that the center of the sun is packed very tight. This is where nuclear fusion occurs. It has been calculated that it takes 14,000 million years

Customer ServiceA set of solar models have been constructed, each based on a single modification to the physics of a reference solar model. In addition, a model combining several of the improvements has been calculated to provide a best solar model. Improvements were made to the nuclear reaction rates, the equation of state, the opacities, and the treatment of the atmosphere. The impact on both

Customer ServiceThe main features of standard solar models, the logic of the calculations, and some of the important results concerning solar neutrinos experiments are given. The input parameters that cause the greatest uncertainties in the calculated neutrino fluxes are the nuclear rection rates, the chemical abundances, the radiative opacity, and the equation of state. This article is based,

Customer ServiceThe standard solar model (SSM) is a mathematical model of the Sun as a spherical ball of gas (in varying states of ionisation, with the hydrogen in the deep interior being a completely ionised plasma).
The Standard Solar Model (SSM) is an important reference in Astrophysics as the Sun stays today the most observed star. This model is used to predict the internal observables like neutrino fluxes and oscillation frequencies and consequently to validate its assumptions for its generalization to other stars.
The standard solar model requires the Sun's luminosity and radius to match the Sun's age. The mass, radius, and luminosity are directly measurable with a relative uncertainty of ±0.02% for the mass of the Sun (Cohen and Taylor 1986). The accuracy of the standard solar model depends directly on the determination of G.
To be considered a standard solar mass model, the model must meet the following requirements: have the observed radius and luminosity of the Sun at the Sun's inferred age, and have a surface composition of hydrogen to heavy elements ratio that matches the observed solar abundances.
Until very recently, the biggest shortcoming of the standard solar model was the solar neutrino predic-tion. Experiments on the earth set an upper bound for the number of neutrinos that could be produced in the sun, and these numbers fell well short of the number of neutrinos predicted by the standard model.
The standard solar model has four basic assumptions, the first being that the sun evolves in hydro-static equilibrium (3). Hydrostatic equilibrium implies a local balance between pressure and gravity, can be expressed as: where P is the pressure, r is the density, and m is the mass contained inside the radius r.
