The Ghost of TIC 160582982: Has TESS Found a Hidden Stellar-Mass Black Hole?

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.
