WEBStars are giant balls of hot gas – mostly hydrogen, with some helium and small amounts of other elements. Every star has its own life cycle, ranging from a few million to trillions of years, and its properties change as it ages.
Stellar structure - Wikipedia
WEBThe internal structure of a main sequence star depends upon the mass of the star. In stars with masses of 0.3–1.5 solar masses ( M ☉ ), including the Sun, hydrogen-to-helium fusion occurs primarily via proton–proton chains , which do not establish a …

WEBWe can’t see directly into a star’s interior. However, just as earthquakes on Earth’s surface reveal what’s going on inside the planet, the behavior of material on the surface of stars provides researchers with information about the interior. Asteroseismology is the study of vibrations of a star.
Star - Wikipedia
WEBA star is a luminous spheroid of plasma held together by self-gravity. [1] The nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night; their immense distances from Earth make them appear as fixed points of light.

WEBFeb 14, 2020 · Stars spend most of their lives repetitively compressing two hydrogen atoms into a single helium atom – plus a lot of energy, which is released as light and heat. What we can learn from the life...
How can we see inside stars? - All About Space
WEBThe art of building an image of a star’s insides is seeing how the sound waves vibrating through its innards cause the surface to slightly vary its brightness. So, since the Kepler Space Telescope stares at the stars constantly it can monitor these slight flickers.
