The concept of apparent black-body temperature is used to describe the radiation received from the moon and the planets.

The use of this concept does not specify the origin of the radiation, and only if the planet really radiates as a black body, will the apparent black-body temperature correspond to the physical temperature of the emitting material.

* Limb ( astronomy ) The outer edge of the apparent disk of as celestial body.

This raises the apparent position of the bottom edge more than the top, reducing the apparent height of the solar disk.

Without an atmosphere, a small star would have an apparent size, an " Airy disk ", in a telescope image determined by diffraction and would be inversely proportional to the diameter of the telescope.

As the investigation unfolded, it became apparent that the entire fan disk and blade assembly from engine number 2, a component approximately in diameter and made of titanium alloy, was missing from the accident scene.

It may be that none of the rings are apparent, in which case the star image appears as a disk ( central maximum only ) rather than as a full diffraction pattern.

of the geometric center of the sun's apparent disk and the ( idealized ) horizon.

Having a uniform disk diameter of arcsec, and given its distance, it is currently believed to be the star with the second largest apparent size as viewed from Earth ( right after the Sun ).

This accretion disk blocks our view of the secondary star, lowering its apparent luminosity and making it difficult for astronomers to pinpoint what its stellar type is.

found a relation for the bias for stars in a galaxy which relates the correction to the variance of the sample and the apparent magnitude, absolute magnitude, and the height above the galactic disk.

The apparent disk of Venus ' extreme crescent measures between 60. 2 and 66 seconds of arc, depending on the distance from Earth.

This transition to BEC occurs below a critical temperature, which for a uniform three-dimensional gas consisting of non-interacting particles with no apparent internal degrees of freedom is given by:

The city is also very windy, which may decrease the apparent temperature.

The temperature difference usually is larger at night than during the day, and is most apparent when winds are weak.

Though the warmer air temperature within the UHI is generally most apparent at night, urban heat islands exhibit significant and somewhat paradoxical diurnal behavior.

This is seen as a variation in effective temperature over the star: the polar temperature is near 10, 000 K, while the equatorial temperature is 7, 600 K. As a result, if Vega were viewed along the plane of its equator, then the luminosity would be about half the apparent luminosity as viewed from the pole.

Remembering that Wien's displacement constant is about 3 mm K, and the temperature of the Big Bang background radiation is about 3 K ( actually 2. 7 K ), it is apparent that the microwave background of the sky peaks in power at 2. 9 mm K / 2. 7 K = just over 1 mm wavelength in the microwave spectrum.

This yields an apparent effective average earth temperature of.

In hot summer weather, a rise in relative humidity increases the apparent temperature to humans ( and other animals ) by hindering the evaporation of perspiration from the skin.

* 1850 – Rankine uses his vortex theory to establish accurate relationships between the temperature, pressure, and density of gases, and expressions for the latent heat of evaporation of a liquid ; he accurately predicts the surprising fact that the apparent specific heat of saturated steam will be negative.

This would raise the apparent temperature so high that people could take off their clothes.

Its mass is about 0. 61 – 0. 62 solar mass, with a surface temperature of 125, 000 ± 5, 000 K. Currently it is 200 times more luminous than the Sun, but its apparent magnitude is only + 15. 75.

The result is also known as the " felt air temperature " or " apparent temperature ".

For example, a wind will lower the apparent temperature by a wider margin at an air temperature of, than a wind of the same speed would if the air temperature were.

However, a study in 2008 suggests that the temperature drop of about 0. 3 ° C in 1945 could be the apparent result of uncorrected instrumental biases in the sea surface temperature record.

The one apparent connection between the two is a score of buildings which somehow or other have survived and which naturally enough are called `` historical monuments ''.

Today our surging strength is apparent to everyone.

After allowing for group exposures, it is apparent that other factors must be considered if we are to comprehend fanaticism.

When we turn to Aristotle's ideas on the moral measure of literature, it is at once apparent that he is at times equally concerned about the influence of the art.

His revolutionary anger is apparent in most of his early poems.

It should be appallingly apparent that city-trading is not a profitable military tactic.

It is apparent from the above and from experimental evidence that the cooling requirements for the anode of free burning arcs are large compared with those for the cathode.

It is presumed that this negative head was associated with some geometric factor of the assembly, since different readings were obtained with the same fluid and the only apparent difference was the assembly and disassembly of the apparatus.

In some programs, treatment is concentrated over a short period of time, while in others, after the initial contact is established, flexible spacing of interviews has been experimentally used with apparent success.

There is no apparent reason why we should feel bound by Swadesh's rules and procedure since his predilections and aims have grown so vast.

A training program in a depressed area may have few enrollees unless there is some apparent prospect for better employment opportunities afterwards, and the prospect may be poor if the training is aimed solely at jobs in the local community.

It is apparent, therefore, that the teacher needs to know what factors have a vital bearing on the learning and adjustment of children.

Although slab stock appeared first, it soon became apparent that for the production of cushions with irregular shapes, crowned contours, or rounded edges, the cutting of slab stock is a wasteful and uneconomical process.

Within the first five minutes of this interview it is apparent to the therapist that `` everybody '' truthfully refers to the woman's husband.

The secretary's greatest achievement is perhaps the rekindling of NATO realization that East-West friction, wherever it take place around the globe, is in essence the general conflict between two entirely different societies, and must be treated as such without regard to geographical distance or lack of apparent connection.

But it is apparent that no acceptable formula has been found to prevent such a possibility.

Hughes said Monday, `` It is the apparent intention of the Republican Party to campaign on the carcass of what they call Eisenhower Republicanism, but the heart stopped beating and the lifeblood congealed after Eisenhower retired.

It is this spirit which explains some of the anomalies of American Catholic higher education, in particular the wasteful duplication apparent in some areas.

The need for lifetime reading is apparent.
