L-Numbered Stars are a classification system used in astronomy to categorize stars based on their luminosity and temperature. The "L" stands for "Late," indicating that these stars are cooler and less luminous than other types, such as O-type or B-type stars. L-Numbered Stars typically have surface temperatures ranging from about 1,300 to 2,000 Kelvin. These stars are often found in the M-dwarf category and are known for their reddish appearance. They play a significant role in the study of stellar evolution and the search for exoplanets, as many L-Numbered Stars are stable and long-lived, providing a conducive environment for planetary systems.
