Chemical cartography might help us better grasp the structure and evolution of our galaxy.
This, in turn, may aid in determining the positions of numerous astronomical objects, such as stars and planets, depending on their chemical composition.
Because we are located inside the Milky Way, astronomers have a limited view of it, making it difficult to explore those far-reaching spiral arms. “It’s like being in a big city. You can look around at the buildings and you can see what street you’re on, but it’s hard to know what the whole city looks like unless you’re in a plane flying above it,” explained Hawkins.
Hawkins believes that with the advent of advanced telescopes, scientists will be able to generate a more exact and sophisticated chemical mapping of the galaxy.Study abstract: Chemical Cartography, or mapping, of our Galaxy has the potential to fully transform our view of its structure and formation. In this work, we use chemical cartography to explore the metallicity distribution of OBAF-type disk stars from the LAMOST survey and a complementary sample of disk giant stars from Gaia DR3. We use these samples to constrain the radial and vertical metallicity gradients across the Galactic disk.
