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.
Carbon monoxide detectors and alarms are designed to alert you to unsafe levels of carbon monoxide. They do this by making noise and flashing lights. However, they also make noise and flash lights under other conditions.
