Impact of the neutron star crust on the tidal polarizability

Understand

The first detection of a binary neutron star merger has opened the brand new era of multimessenger astronomy.

• This historic detection has been instrumental in providing constraints on the tidal polarizability of neutron stars.
• In turn, the tidal polarizability has been used to impose limits on stellar radii and ultimately on the equation of state (EOS).
• The tidal polarizability is also sensitive to the second tidal Love number k2.
