"WebSupergiants have the largest radius of all known stars. They evolve from large main-sequence stars. Supergiants can contain 8 - 200 times the mass of the Sun! They also shine brightly. One supergiant can be as bright as a million Suns. The colour of supergiants can be red or blue. Red supergiants have low surface temperatures, below 4,100 K. " - Red giant mass

WebA number of factors can contribute to the loss of mass in giant stars, including: Gravitational attraction of a binary companion; Coronal mass ejection-type events; Ascension to red giant or red supergiant status; Solar wind. The Sun, a low-mass star, loses mass due to the solar wind at a very small rate, (2–3) × 10 −14 solar masses per year. WebFusion creates extra radiation pressure and this will cause the Sun to expand. The outer layers of hydrogen will decrease in temperature, which will make them redder, and the Sun will then be a red giant. All main sequence stars that are about 1/5 to 10 times the mass of the Sun will become red giants. [1] Figure 12.1 Image credit
