Binary stars are all around us, new map of solar neighborhood shows
A UC Berkeley doctoral student has mined the most recent Gaia survey for all binary stars near Earth and created a 3D atlas of 1.3 million of them. The last local survey included about 200 binary pairs. With such census data, astronomers can conduct statistical analyses on binary populations. For pairs that contain white dwarfs, it's possible to determine the age of their main-sequence companion, and thus of any exoplanets around them. (2021-02-22)
