When Gaia meets Hubble: accurate proper motions for faint stars
A powerful new tool combines data from Gaia and the Hubble Space Telescope and accurately measures how stars move on the plane of the sky. Find out how it’s done in today’s Astrobite!
Going with the Tide: Does tidal dissipation play an important role in stellar/black hole mergers?
In today’s paper: how does tidal dissipation and gravitational wave emission affect the result of encounters between stars and black hole binaries in stellar clusters?
