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.
There is a group of stars which appears deep red like19 or TX Piscium. These are the carbon stars because they have abundance of carbon molecule such as C2, CH and CN in their outer layers which absorb most of photon in the blue and violet region of spectrum. Thus the light coming from the stars appears deep red in color. They are collectively referred to as type C (Carbon) stars. Conclusion: The color of a star is mainly decided by the surface temperature of the star but other factors also affect color of the star. Human eye is more sensitive to blue light than red in the night which gives bluish appearance to the stars.
