Topic 3: The Spectroscope - Danielle`s science9 weebly
... The significance of the spectral lines was discovered about 50 years later when Kirschoff and Bunsen, two chemists used a spectroscope to observe various chemicals when they were heated. They found some of the lines missing in some of the chemicals. Each particular element had its own unique spectra ...

Observations and Theoretical Models of Subdwarfs

Four years later, Gerard Kuiper renamed them “subdwarfs” after observing that these intermediate stars had less in common with the degenerate white dwarfs than they did with main sequence dwarf stars [1].

Supernova - Mid-Pacific Institute
... A supernova is an explosion of a massive supergiant star. Occurs at the end of a stars lifetime when its nuclear fuel is exhausted and is no longer supported by the release of nuclear energy. The enrichment of the gas in our region of the milky way reached such a point that a sufficient quanti ...

P2_5 The Apparent Magnitude of α Orionis Supernova
... It has been found that when α Orionis becomes a supernova, it will be visible during the day. However, it will appear as a bright star rather than illuminating the Earth in the same way as the sun or moon. The moon has a mean apparent magnitude of -12.74 [6], and gives just enough light to help see ...

... D6. (2 pts) When modern astronomers redesigned the magnitude system, they set the scale so that every five magnitudes is 100 times brighter (or dimmer, depending on direction). If star A is 1 magnitude brighter than star B, how many times brighter is it? Give your answer to the nearest thousandth. ...

As time passes, we realize that they are moving utterly independently, not orbiting one another, so not a true binary at all. Their motions give us no useful information. ...
