Gravity Seminar: Scalar wave emission in theories with kinetic screening, Dina Traykova, AEI Potsdam

March 31, 2023 @ 2:30 pm - 4:00 pm

I will discuss a recent work studying the gravitational wave emission and in particular the scalar wave monopole and quadrupole modes in a scalar-tensor theory with a kinetic screening effect. This theory serves as a viable model of cosmic acceleration and passes existing tests of gravity. In this talk I will present our numerical simulations for a static and a non-spherically oscillating neutron star and discuss how the screening effect suppresses the scalar wave emission from the neutron star oscillations.
