    Using Hubble, researchers measure the mass of a single white dwarf for the first time

    by Haygen Warren February 6, 2023
    written by Haygen Warren

    Of the trillions of stars scattered throughout the universe, one of the most common are the white dwarfs, which are the dormant, burned out, and leftover cores of low/medium mass stars. For decades, scientists have only measured the masses of white dwarfs within binary star systems. While these measurements provide insight into the true masses of white dwarfs, the measurements typically feature high amounts of uncertainty.

    With help from the joint NASA/European Space Agency (ESA) Hubble Space Telescope, a team of researchers directly measured the mass of an isolated white dwarf outside of a binary star system. Found to be approximately 56% of the Sun’s mass, the team’s results agree with previous white dwarf mass predictions and provide insight into the evolutionary processes of dead stars.
