solar luminosity

Solar luminosity is about two thousand times that of its G8 companion.

Even the largest red dwarf has only about 10% of the Solar luminosity.

And solar luminosity dropped another quarter of one percent.

A mechanism that may account for periodic fluctuations in solar luminosity has also been proposed as an explanation.

The quasar's luminosity is estimated at 6.3x10 solar luminosities.

This rate of removal would be sufficient to counter the effects of increasing solar luminosity for the next two billion years.

Spectral type's a cool G. Main sequence, about three-fifths solar luminosity.

Luminosity is estimated to be 3000 Solar luminosity.

It is also the most luminous globular cluster in the Milky Way, at over one million solar luminosities.

Scientists have speculated on possible relationships between sunspots and solar luminosity since the historical sunspot area record began in the 17th century.

At this point in the simulation solar luminosity is programmed to decline, retracing its original path to its initial value.

An abbreviation for solar masses, solar radii, or solar luminosities.

The researchers showed that even with a constant solar luminosity the poles were capable of jumping between states of depositing or losing ice.

The luminosity of the Class 0 protostars is high - a solar-mass protostar may radiate at up to 100 solar luminosities.

One prediction of the simulation is that the biosphere works to regulate the climate, making it habitable over a wide range of solar luminosity.

Simultaneously, the Sphere's wall added another spurt of acceleration, and the solar luminosity dimmed by one half of one percent.

Solar luminosity is about 0.9 W/m brighter during solar maximum than during solar minimum.

Given a surface temperature of 5,068 Kelvin, theoretical calculations would yield a total luminosity for the star of about 60 times the solar luminosity.

The solar luminosity is related to the solar irradiance measured at the Earth or by satellites in Earth orbit.

It is this number which constitutes the basic metric used in astronomy and is known as 1 solar luminosity, the symbol for which is .

Various factors are known to influence the climate, including ocean currents, surface albedo, greenhouse gases, variations in the solar luminosity, and changes to the planet's orbit.

So the changes in the spectral lines tell us of changes in the Sun's temperature, which in turn reveal changes in the solar luminosity.

Flares usually occur in the presence of sunspots, and hence the two are correlated, but flares themselves make only tiny perturbations of the solar luminosity.

By investigating the measured fluxes, angular diameter, and mass of the nebula, a distance of 5.5kpc and luminosity of 38 solar luminosities was determined.
