The lifespan of L-type stars ranges from billions to tens of billions of years.
Stars are giant spheres made of glowing plasma—mainly hydrogen, helium, and trace amounts of heavier elements. Among the approximately 300 billion stars in the Milky Way system, the brightness of the star is called its magnitude. The brighter the star, the lower its magnitude. Astronomers also compiled star catalogs to facilitate research.
Stars undergo nuclear fusion in their cores to produce energy that is transmitted outward and then radiated from the surface into outer space. Once the nuclear reactions in the core are exhausted, the life of the star is about to end. At the end of their lives, stars also contain degenerate matter.
Differences in star size and mass will lead to different endings: white dwarf, neutron star, black hole. Two or more gravitationally bound stars can form binaries or clusters, and when such stars are in relatively close orbits, the exchange of material between them can have a significant impact on their evolution.
Basic information
The only organization recognized by the academic community to name stars or celestial bodies is the International Astronomical Union. There are many private companies that sell star names, but these names are neither recognized by the scientific community except by the buyers.
No one will use this name, and there are many organizations pretending to be astronomical institutions to commit fraud, tricking ignorant people into buying the names of stars.
