solar radius:
R_odot = 6.960 times 10^{8} m
Large lengths, such as the radius of a giant star or the semi-major axis of a binary star system, are often expressed in terms of the astronomical unit (AU) — ...
Solar radius = 695,990 km = 432,470 mi = 109 Earth radii Solar mass = 1.989 1030 kg = 4.376 1030 lb = 333,000 Earth masses Solar luminosity (energy output of the Sun) = 3.846 1033 erg/s ...
2536 times the solar radius. Would fill the orbit of Saturn. Could pack more than 1 billion suns into the same volume.
How Bright:
38,000 times brighter than the sun. Absolute visual magnitude, Mv =-6.7 ...
15 solar radius above the LIMB. BURST. A transient enhancement of the solar RADIO EMISSION, usually associated with an ACTIVE REGION or FLARE. CARRINGTON LONGITUDE. A system of fixed longitudes rotating with the sun. CENTIMETER BURST.
In the Sun, a convection zone extends from just below the photosphere to about seventy percent of the solar radius.
Corona The outermost layer of the solar atmosphere.
0 solar radius), and are practically inobservable at the surface. The restoring force is caused by adiabatic expansion: in the deep interior of the Sun, the temperature gradient is weak, ...
The stars are youthful hydrogen-fusing "dwarfs" (so called in spite of their being 8 and 5 times the solar radius) that are only about 10 million years old. Both are massive stars, 15 and 9 times solar.
The radiative zone extends from ~25% to 85% of the solar radius. Here, and in the core, the primary transport of energy is by the movement of photons; temperatures range from 0.5-8 x 106 K with densities from 0.01-10 g/cm3.
Parker's model predicted that the wind should make the transition to supersonic flow at an altitude of about 4 solar radii from the photosphere; but the transition (or "sonic point") now appears to be much lower, perhaps only 1 solar radius above ...
068 solar radius. Saturn pulls the sun another 408,000 km (or 0.586 solar radius). This is known as the barycenter of a system. When all of the Jovian planets are on the same side, the tug is 2.169 solar radii.
Just knowing the solar radius and Mass and that the sun is supported in hydrostatic equilibrium basically sets the interior temperature.
The Earth-Sun distance is defined as the astronomical unit, and is equal to km (IAU 1976). The Sun's luminosity is J s-1, the solar mass is kg, and the solar radius is m. The sun is approximately 4.
5. The Sun appears to have a well-defined edge because the thickness of the _____ is only 0.1 percent of the solar radius. (Hint)
6. The most abundant element in the Sun is _____. (Hint) ...
Convection Zone
a layer in a star in which convection currents are the main mechanism by which energy is transported outward. In the Sun, a convection zone extends from just below the photosphere to about seventy percent of the solar radius.
Radius: The radius of a star or planet is the distance from the center of the star or planet out to its surface. Radius is equal to half the diameter. Star sizes are often compared to the solar radius which is 7 × 1010 cm.
the Earth-Sun distance) and that the spots show a variation of 500 degrees compared to the star's average temperature of 3,600 degrees kelvin. This is in stark difference to the Sun where the convection cells rarely exceed 1/20th of the solar radius ...
009 AU (less than half a solar radius). Their periods are scattered from 400 to 2,000 years, and their last passages occurred between 1880 and 1970. The most famous fragment of the group is Comet Ikeya-Seki 1965 VIII.
Or perhaps it would have the same radius but a more condensed core with a larger percentage of the solar radius in the low pressure, low density convective envelope.
