Characteristics determines color of star
WebIf m1 and m2 are the magnitudes of two stars, then we can calculate the ratio of their brightness ( b 2 b 1) using this equation: m 1 − m 2 = 2.5 log ( b 2 b 1) or b 2 b 1 = 2.5 m 1 − m 2. Here is another way to write this equation: b 2 b 1 = ( 100 0.2) m 1 − m 2. Let’s do a real example, just to show how this works. WebFeb 25, 2015 · Thus, they appear red, while hot stars — in which particles are moving much more quickly — emit more energy and thus emit mostly at blue and ultra-violet wavelengths, making them appear blue or white. Age Throughout most of a star's life, it is burning hydrogen at its core, which creates lots of energy and thus makes it appear blue.

WebA) All stars put out most of their light in the visible range of the spectrum. B) In order to measure the total apparent brightness of a star, you must measure its brightness in all wavelengths, and this is difficult to do. The only wavelengths you can measure from the surface of Earth are visible and radio wavelengths. WebJul 20, 2016 · The colour of a star determines by its temperature.

WebThe surface temperature of the stars are plotted on the x axis and the absolute brightness on the y axis. Most stars are are main sequence stars. As main sequence stars surface … WebAs shown in the Hertzsprung-Russell Diagram, Main Sequence stars span a wide range of luminosities and colors, and can be classified according to those characteristics. The smallest stars, known as red dwarfs, may contain as little as 10% the mass of the Sun and emit only 0.01% as much energy, glowing feebly at temperatures between 3000-4000K.

Super Giant - Low temperature, high luminosity stars. Main sequence - Small dim stars that remain after nuclear fusion.
WebThe total energy emitted per second by a star is called its luminosity. How bright a star looks from the perspective of Earth is its apparent brightness. The apparent brightness of a star depends on both its luminosity and its distance from Earth. Thus, the determination of apparent brightness and measurement of the distance to a star provide ...
