In this webinar, we'll explore the discoveries of compact objects like black holes and neutron stars in the universe. We'll discuss the star formation history and delve into the properties of black holes and neutron stars. Additionally, we'll provide a brief overview of the merger process of black hole-neutron star binary systems. We'll also cover the signature detection of these events through emitted radiation and observations from various observatories. By studying black hole-neutron star binaries, we aim to contribute valuable insights to the field of Astronomy.
