For example, the giant elliptical galaxy M87 has an absolute magnitude of − 22 ( i. e. as bright as about 60, 000 stars of magnitude − 10 ).

For nearby astronomical objects ( such as stars in our galaxy ) luminosity distance D < sub > L </ sub > is almost identical to the real distance to the object, because spacetime within our galaxy is almost Euclidean.

For the most part, Bayer assigned Greek and Latin letters to stars in rough order of apparent brightness, from brightest to dimmest, within a particular constellation.

For example, the asterism known as the Big Dipper corresponds to the seven brightest stars of the larger IAU constellation of Ursa Major.

For example, the " Little Dipper " asterism of the constellation Ursa Minor has ten stars with Bayer designation, α UMi to π UMi.

For the Sun and stars with low temperatures, the prominence of the H and K lines can be an indication of strong magnetic activity in the chromosphere.

For more massive stars, electron degeneracy pressure will not keep the iron core from collapsing to very great density, leading to formation of a neutron star, black hole, or, speculatively, a quark star.

( For very massive, low-metallicity stars, it is also possible that instabilities will destroy the star completely.

For instance, galaxies contain more young stars and are less clustered, and quasars appear more numerous.

For example, if there is a triple star system in which two stars orbit each other closely while a third star is in a more distant orbit, the two closely orbiting stars would be considered a component with two subcomponents.

For example, teachers can alter student behavior by systematically rewarding students who follow classroom rules with praise, stars, or tokens exchangeable for sundry items.

For example, it implies the existence of black holes — regions of space in which space and time are distorted in such a way that nothing, not even light, can escape — as an end-state for massive stars.

For example, following the ideas of Greek philosopher and scientist Aristotle, scientists reasoned that a cannonball falls down because its natural position is in the earth ; the sun, the moon, and the stars travel in circles around the earth because it is the nature of heavenly objects to travel in perfect circles.

For this purpose he used a set of stars that had reliable parallaxes and many of which had been categorized at Harvard.

For the cooler stars, dwarfs such as red dwarfs, orange dwarfs, and yellow dwarfs are indeed much smaller and dimmer than other stars of those colors.

For those stars the terms dwarf and giant refer to differences in spectral lines which indicate if a star is on the main sequence or off it.

For example, white dwarfs are a different kind of star that is much smaller than main-sequence stars — being roughly the size of the Earth.

For the Praesepe, he found more than 40 stars.

For a typical cluster with 1, 000 stars with a 0. 5 parsec half-mass radius, on average a star will have an encounter with another member every 10 million years.

* For the company's 90th anniversary, in 2002, a completely new version of the logo was introduced in which shooting stars would fall from a night sky to form the arc while the Paramount logo would fly into place between them.

For example, a few percent change in the value of the fine structure constant would be enough to eliminate stars like our Sun.

For example, children with childhood absence epilepsy may be susceptible to hyperventilation.

For example, in the absence of any new technologies, copper prices would indeed be expected to increase as growing economies demanded more copper to meet the needs of expanding communication networks and plumbing infrastructure.

For instance, in the Atlas Mountains of northwest Africa, the end of the Upper Paleolithic period coincides with the end of the Aterian tradition of producing laminar microliths, and deposits can be dated by the presence or absence of these artifacts.

For example, photoreceptor cells in the retina constantly release the neurotransmitter glutamate in the absence of light.

For example, the absence of the tuple (' John ', ' Spanish ') from a table of language skills cannot necessarily be taken as evidence that John does not speak Spanish.

For them, ' primitive ' denotes irrational use of resources and absence of the intellectual and moral standards of ' civilised ' human societies .... From the standpoint of anthropological knowledge, both these views are equally one-sided and simplistic.

For a thing whose presence or absence makes no visible difference, is not an organic part of the whole.

For quadrupedal species, there are numerous gaits which may be termed walking or running, and distinctions based upon the presence or absence of a suspended phase or the number of feet in contact any time do not yield mechanically correct classification.

For some time, it was unclear whether Carey would return to AFL football, but after the end of the 2002 season and a 12 month absence from football, Carey was signed up by the Adelaide Crows, where he played for the next two seasons.
