Sentences with phrase «angular distance from»

Factors affecting that difference apart from those already mentioned are: the different angular distance from a target within which EBs become diluted and cause a false positive; here Brown uses a radius of 20 whereas for CoRoT, diluted EBs found by the photometric follow - up infer a radius of about 17 (Deeg et al. 2009).

Not exact matches

A planet's angular momentum equals the mass of an object multiplied by its distance from the Sun, and corresponds with the force that the planet exerts on the overall system's spin.

By comparing the angular differences in those paths to the geographic distances between the observers, astronomers could calculate Earth's distance from Venus.

Despite their hunches, researchers have been unable to prove that the visual system measures distance with angles because they couldn't separate angular declination from other visual cues.

The spin of such cosmic objects is described by a conserved quantity called angular momentum, which accounts for both the speed of the rotating mass and its distance from the spin axis.

This list is every galaxy with an angular size greater than 1.8 arcminutes within 7.5 degrees of the centre of the cluster which at a distance of 52 million light years corresponds to every galaxy with a diameter greater than 30 thousand light years within 7 million light years from the centre.

The linear distance from the galaxy center = -LSB-(2p × (distance to the galaxy) × (angular distance in degrees)-RSB- / 360 °.

The new technique is similar to that used by land surveyors on earth, who measure both the physical and angular — or «apparent» — size of a distant object, to calculate its distance from Earth.

The angular distance of the piece of the disk from the center is measured, but to use the enclosed mass formula, the piece of the disk's actual linear distance from the center must be found.

Remember way back in the planetary science chapter that the linear distance can be found from the angular distance if you know the distance to the object?

A point source is detected at an angular distance of 3.5» from the central star.

If the angular distance of a star from the radiant is λ and if the velocity of the cluster as a whole with respect to the Sun is V, then the radial velocity of the star, Vr, is Vr = V cos λ.

There is a significant loss of rotational energy due to tidal drag transferring angular momentum from Earth's axial rotation to the Earth - Moon system (Earth slows, EM distance increases).

I accept that there are complex weather systems bubbling away at any given point over the earth's surface but, on a planetary scale as the earth rotates on its axis, I suggest these will essentially average out, at similar angular distances as from the sub-solar point, at decadal and centennial timeframes.

Another thing which I would like clarified is the planet's distance from the Sun, its Angular Momentum and its consequent effect on the Sun.

The chord can be described using the angular position of the endpoints, or the coordinates of the midpoint, or the orientation and distance from the centre.

A planet's angular momentum equals the mass of an object multiplied by its distance from the sun, and corresponds with the force that the planet exerts on the overall system's spin.
