मानक-मोमबत्ती इसके अंग्रेजी अर्थ का उदाहरण

The first "standard candles" were made from spermaceti wax.

By 1900 Price's Patent Candle were producing 130 differently named and specified sizes of candle, any one of which could in theory be manufactured in 60 different permutations of material, colour and hardness; the company regularly held 2,000 different standard candle products in stock.

He initially worked on the replacement of the standard candle, used to determine the quality of the gas for lighting, by the Harcourt pentane lamp.

Distances can also be measured using standard candles; many different types of standard candles and rulers are needed to construct the cosmic distance ladder.

Their consistent peak luminosity allows these explosions to be used as standard candles to measure the distance to their host galaxies: the visual magnitude of a type"nbsp;Ia supernova, as observed from Earth, indicates its distance from Earth.

Details of the pre-nova moments may help scientists better judge the quality of Type Ia supernovae as standard candles, which is an important link in the argument for dark energy.

Double degenerate scenarios raise questions about the applicability of Type"nbsp;Ia supernovae as standard candles, since total mass of the two merging white dwarfs varies significantly, meaning luminosity also varies.

In a series of papers in the 1990s the survey showed that while Type Ia supernovae do not all reach the same peak luminosity, a single parameter measured from the light curve can be used to correct unreddened Type Ia supernovae to standard candle values.

The original correction to standard candle value is known as the Phillips relationship.

The similarity in the absolute luminosity profiles of nearly all known Type"nbsp;Ia supernovae has led to their use as a secondary standard candle in extragalactic astronomy.
