Statins are a group of medicines that can help lower the level of low-density lipoprotein (LDL) cholesterol in the blood. LDL cholesterol is often referred to as bad cholesterol, and statins reduce the production of it inside the liver.aving a high level of LDL cholesterol is potentially dangerous, as it can lead to a hardening and narrowing of the arteries (atherosclerosis) and cardiovascular disease (CVD) . CVD is a general term that describes a disease of the heart or blood vessels. It is the most common cause of death in the UK.
The colour of a star is primarily a function of its effective temperature. You should recall that a star approximates the behaviour of a black body radiator. As a black body gets hotter its colour changes. If you were to heat a solid shot put it would first emit radiation in the infrared region.
Cool stars (such as Betelgeuse, which has a surface temperature of T = 3500 Kelvin) emit more red and orange light than blue and violet light. Thus, cool stars are red. Hot stars (such as Rigel, which has a surface temperature of T = 15,000 Kelvin) emit more blue and violet light than red and orange light. Thus, hot stars are blue. One way of classifying stars is by their temperature; stellar temperatures run from about 2500 Kelvin to about 50,000 Kelvin.
