The LIGO and Virgo observatories recently detected gravitational waves from a compact binary coalescence involving a 23 solar mass black hole and 2.6 solar mass compact object. The source has the most unequal mass ratio yet measured with gravitational waves, and its secondary component is either the lightest black hole or the heaviest neutron star discovered in a double compact-object system. These properties challenge current models for the formation and mass distribution of compact binaries. In this talk, I will discuss GW190814's unique features, investigate the nature of its secondary component, and highlight possible implications for the neutron-star equation of state.
