A single origin story for the Milky Way's most mysterious stars

Astronomers discovered black hole stars, described as ancient, bright, and gargantuan objects. One such object, MoM-BH*-1, is the size of our solar system. Researchers believe these objects may explain the little red dots observed by the James Webb Space Telescope in the early universe. This discovery follows previous theories suggesting that young, massive stars orbiting Sagittarius A* originated from a single gas disk reshaped by an intermediate-mass companion.

  1. Researchers identify black hole stars as possible early universe markers

    Astronomers discovered black hole stars, described as ancient, bright, and gargantuan objects. One such object, MoM-BH*-1, is the size of our solar system. Researchers believe these objects may explain the little red dots observed by the James Webb Space Telescope in the early universe. This discovery follows previous theories suggesting that young, massive stars orbiting Sagittarius A* originated from a single gas disk reshaped by an intermediate-mass companion.

    Why it matters

    The composition of a galaxy's stellar population drives its overall evolution. In the Milky Way's bulge and disk, stars and stellar remnants account for roughly 85% of the baryonic mass.

    Still unconfirmed

    • MoM-BH*-1 is a black hole star the size of our solar system.
    • Black hole stars are ancient, bright, and gargantuan.
    • Black hole stars may explain the little red dots in the early universe.
    • Stars and dead stars make up about 85% of the baryonic mass in the Milky Way's disk and bulge.

    What to watch next

    • Confirmation of the physical properties of MoM-BH*-1 via additional telescope data.
    • Peer review of the link between black hole stars and little red dots.

  2. Unified Origin Theory for Mysterious Milky Way Stars

    A research team has proposed a single dynamical model to explain young, massive stars orbiting Sagittarius A*. These stars exhibit three different orbital behaviors that may have originated from one gas disk. An intermediate-mass companion likely reshaped their orbits.

    What's confirmed:

    • Sagittarius A* is a supermassive black hole with a mass four million times that of the sun.
    • Three groups of young, massive stars near Sagittarius A* show radically different orbital behaviors.

    Still unconfirmed:

    • IRS-13E is the prime suspect for the intermediate-mass companion that reshaped the stars' orbits.
    • A team led by Xiaochen Zheng at the Beijing Academy of Science and Technology proposed the unified dynamical model.
