solar radius

This star has nearly 11 times the solar radius and is about 62 times the luminosity of the Sun.

In astronomy, the 'solar radius' is a unit of length used to express the size of stars.

Their orbital period is 1.57 days and they are separated by an estimated distance of only 15 solar radii along a circular orbit.

Instead, the white dwarf stabilized at an orbit approximately one solar radius away from the pulsar.

This allows a direct calculation of the actual diameter, which is in good agreement with the 1,050 solar radii derived by other methods.

After all this time, she had drifted to within no more than a third of a Solar radius of the center of the Sun itself.

If Gilliland is correct, the true value of the mean solar radius is more nearly 959.8 seconds of arc.

In solar-terrestrial terms, a large gaseous stream (surge) that moves outward more than 0.15 solar radius above the limb.

The simulations only cover a very small fraction of the solar radius, and are evidently far too time-consuming to be included in general solar modeling.

The star's angular diameter and a linear radius of 450 Solar radii have been measured in three colors by lunar occultation.

Below about 0.7 solar radii, solar material is hot and dense enough that thermal radiation is the primary means of energy transfer from the core.

Since the Earth is about 216 solar radii from the Sun, the solar-wind image must be enlarged about 216 times when it reaches us.

The radius of the primary is estimated at 60 solar radii, and its mass is estimated to be 25 solar masses.

Radius is measured in standard solar radii or kilometers, and mass in standard solar masses.

Alan D. Fiala (b. 1942) is an expert on predicting and observing eclipses, with special application to precise measurement of the solar radius.

They are confined to the interior of the sun below the convection zone (which extends from 0.7-1.0 solar radius), and are practically inobservable at the surface.

David Herald and Paul Muller presented their analysis under the heading 'Observation of a probable change in the solar radius between 1715 and 1979'.

In other words, the solar radius at which we see the optical depth as being unity increases as we move our line of sight towards the limb.

Observations made in the near-infrared spectrum indicate that it has a radius of 500 solar radii, and its temperature is between 2405 and 2485 degrees Kelvin.

This is a region where rotation changes from differential in the convection zone to nearly solid-body rotation in the interior, at 0.71 solar radii from the center.

The red supergiant primary, known as VV Cephei A, is currently recognised as one of the largest stars in the galaxy, with an estimated solar radius between 1,050 and 1,900.

Has a radius larger than 2.6 times the solar radius and a 60% greater mass than the Sun The projected rotation speed measured in the km/s- -42 probably corresponds to this star.

The star is approximately 1000 times larger than our Sun's solar radius, and were it placed in the Sun's position, its radius would reach between the orbit of Jupiter and Saturn.

The Solar Orbiter (SOLO) will approach to 62 solar radii to view the solar atmosphere with high spatial resolution in visible, XUV, and X-rays.

But measurements of the solar constant since 1850 implied that the solar radius must have been constant to within 0.3 seconds of arc per century, less than half the variation in the records at Greenwich.
