Testing fundamental physics with solar twin stars

点击翻译按钮获取中文摘要

This project aims to test the variation of fundamental physical constants across our galaxy by using twins of our Sun, a new probe that unlocks a 1000-fold sensitivity gain. The standard model of nature's laws cannot explain fundamental constants, like electromagnetism's strength, alpha. By discovering distant solar twins, the project intends to probe alpha in regions of very different Dark Matter density, opening an unexplored discovery space. Expected outcomes include the most precise astronomical measurement of a fundamental constant, and the first test of variations in alpha across our Galaxy's Dark Matter field.
