Intriguing Revelations from Lithium, Beryllium, and Boron

The three elements, Li, Be, and B, are very rare in the Universe. Although they are made in stars, they are readily destroyed by nuclear reactions in stellar interiors. Even so, their surface contents have provided astronomers with insights into the insides of stars. Some Li is produced in the Big Bang and the Li content of the oldest stars has contributed to our understanding of the early universe. Some of the history and the puzzles in this field will be presented.
