Using @mcdonaldobs, we derived the detailed chemical fingerprint of 50 'twin' stars residing in wide binary stellar system, and found that typically (~80% of the time ) they are chemically identical (at a level of well below 0.05 dex)! This is good news for chemical tagging.

Chemical tagging is an idea that says one can uncover the birth place of a star given only its detailed chemical properties. If true, chemical tagging will allow astronomers to reconstruct the history of the Milky Way.

Though i have to admit the one of the best parts was collaborating with
@alexanderpji@johannateske, Kareem El-badry, Yuan-Sen Ting, and my own group of amazing grad and undergrads (Maddie Lucey,@DreiaCarrillo, Tyler Nelson, Megan Thompson and Dustin Katzburg)Prikaži ovu nit -
and for the astronomers here's the arxiv link : https://arxiv.org/abs/1912.08895
