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. Carbon monoxide is difficult to detect because it has no smell, taste or colour. This means you can inhale it without realising. Carbon monoxide is produced when fuels such as gas, oil, coal or wood do not burn fully. When a fire burns in an enclosed space, such as a room, the oxygen is gradually used up and replaced with carbon dioxide. The fuel is unable to burn fully and releases carbon monoxide.
