JINAbase: A database for chemical abundances of metal-poor stars

Understand

Reconstructing the chemical evolution of the Milky Way is crucial for understanding the formation of stars, planets, and galaxies throughout cosmic time.

• Different studies associated with element production in the early universe and how elements are incorporated into gas and stars are necessary to piece together how the elements evolved.
• These include establishing chemical abundance trends, as set by metal-poor stars, comparing nucleosynthesis yield predictions with stellar abundance data, and theoretical modeling of chemical evolution.
• To aid these studies, we have collected chemical abundance measurements and other information such as stellar parameters, coordinates, magnitudes, and radial velocities, for extremely metal-poor stars from the literature.
