Astronomers have discovered a massive, unseen object lurking in the orbit of a distant, pulsating star. By “listening” to the rhythmic vibrations of the star TIC 160582982, researchers detected the gravitational tug of a mysterious companion that is heavy enough to be a neutron star or even a stellar-mass black hole, yet emits no conspicuous light of its own.

The discovery, detailed in a recent paper by a team of astronomers including Chenglong Lv, Javier Pascual-Granado, and Ali Esamdin, highlights the power of a technique called asteroseismology, therefore the study of “starquakes” and stellar vibrations.
