The parsec symbol: pc is a unit of length used to measure the large distances to astronomical objects outside the Solar System. One parsec is approximately equal to 31 trillion kilometres 3. A parsec is obtained by the use of parallax and trigonometryand is defined as the distance at which one astronomical unit subtends an angle of one arcsecond i. The parsec unit was probably first suggested in by the British astronomer Herbert Hall Turner.
Partly for this reason, it is the unit preferred in astronomy and astrophysicsthough the light-year remains prominent in popular science texts and common usage. Although parsecs are used for the shorter distances within the Milky Waymultiples of parsecs are required for the larger scales in the universe, including kiloparsecs kpc for the more distant objects within and around the Milky Way, megaparsecs Mpc for mid-distance galaxies, and gigaparsecs Gpc for many quasars and the most distant galaxies.
This corresponds to the small-angle definition of the parsec found in many contemporary astronomical references. The parsec is defined as being equal to the length of the longer leg of an extremely elongated imaginary right triangle in space. The two dimensions on which this triangle is based are its shorter leg, of length one astronomical unit the average Earth-Sun distanceand the subtended angle of the vertex opposite that leg, measuring one arc second.
Applying the rules of trigonometry to these two values, the unit length of the other leg of the triangle the parsec can be derived. One of the oldest methods used by astronomers to calculate the distance to a star is to record the difference in angle between two measurements of the position of the star in the sky. The first measurement is taken from the Earth on one side of the Sun, and the second is taken approximately half a year later, when the Earth is on the opposite side of the Sun.
The distance between the two positions of the Earth when the two measurements were taken is twice the distance between the Earth and the Sun. The difference in angle between the two measurements is twice the parallax angle, which is formed by lines from the Sun and Earth to the star at the distant vertex. Then the distance to the star could be calculated using trigonometry. The parallax of a star is defined as half of the angular distance that a star appears to move relative to the celestial sphere as Earth orbits the Sun.
Equivalently, it is the subtended angle, from that star's perspective, of the semimajor axis of the Earth's orbit. The star, the Sun and the Earth form the corners of an imaginary right triangle in space: the right angle is the corner at the Sun, and the corner at the star is the parallax angle. The length of the opposite side to the parallax angle is the distance from the Earth to the Sun defined as one astronomical unit auand the length of the adjacent side gives the distance from the sun to the star.
Therefore, given a measurement of the parallax angle, along with the rules of trigonometrythe distance from the Sun to the star can be found. A parsec is defined as the length of the side adjacent to the vertex occupied by a star whose parallax angle is one arcsecond. The use of the parsec as a unit of distance follows naturally from Bessel's method, because the distance in parsecs can be computed simply as the reciprocal of the parallax angle in arcseconds i.
No trigonometric functions are required in this relationship because the very small angles involved mean that the approximate solution of the skinny triangle can be applied.
Though it may have been used before, the term parsec was first mentioned in an astronomical publication in Astronomer Royal Frank Watson Dyson expressed his concern for the need of a name for that unit of distance.
He proposed the name astronbut mentioned that Carl Charlier had suggested siriometer and Herbert Hall Turner had proposed parsec. By definition, 1 Astronomical unit 1 au of arc length subtends an angle of 1 arc second 1" at the center of the circle of radius 1 parsec 1 pc. In the diagram above not to scaleS represents the Sunand E the Earth at one point in its orbit.
Thus the distance ES is one astronomical unit au. Through trigonometrythe distance SD is calculated as follows:. A corollary states that a parsec is also the distance from which a disc one astronomical unit in diameter must be viewed for it to have an angular diameter of one arcsecond by placing the observer at D and a diameter of the disc on ES.
Mathematically, to calculate distance, given obtained angular measurements from instruments in arcseconds, the formula would be:. The calculated stellar distance will be in the same measurement unit as used in Distance earth-sun e. As the astronomical unit was defined by the IAU as an exact SI length in metres, so now the parsec corresponds to an exact SI length in metres. To the nearest meter, the small-angle parsec corresponds to 30,, m. The parallax method is the fundamental calibration step for distance determination in astrophysics ; however, the accuracy of ground-based telescope measurements of parallax angle is limited to about 0.
Between andthe Hipparcos satellite, launched by the European Space Agency ESAmeasured parallaxes for about stars with an astrometric precision of about 0. Distances expressed in fractions of a parsec usually involve objects within a single star system.

I've just downloaded and install the last driver version and I still have the same issue no update for my previous driver version.
Please let us know if this chipset support this game. This is an article published for Battlefield 3 and 4 but also applicable to Need for Speed Rivals. You may have the "software version" of DirectX 11 installed, but Battlefield requires this specific Direct X hardware support.
