Stellar Evolution: From Protostars to the Main Sequence. (also see Review of Heat Flow Inside Stars) As previously discussed, most of the formation time between the initial collapse of an interstellar cloud and the formation of the star that results from that collapse is spent in a slow contraction.
Carbon monoxide is an odorless, colorless, and tasteless gas that is near impossible to identify without a proper detector. It is caused by fuels not burning completely, including wood, gasoline, coal, propane, natural gas, gasoline, and heating oil.
The difference between a Carbon Monoxide (CO) detector and a Combustible Gas detector is not always clear. Carbon Monoxide (CO) is the byproduct of combustion. Sources of Carbon Monoxide can include furnaces, gas appliances, vehicles (garages), and anything else that uses a combustion process (i.e., a flame). Carbon Monoxide is particularly dangerous because it is odorless.
