Detectability of Massive Boson Stars using Gravitational Waves from Fundamental Oscillations
Swarnim Shirke, Bikram Keshari Pradhan, Debarati Chatterjee +2
Boson Stars are macroscopic self-gravitating configurations made of complex scalar fields. These exotic compact objects would manifest as dark Boson stars and, in the absence of el…
Fundamental oscillations as a tool to distinguish boson stars from neutron stars and black holes
Swarnim Shirke, Bikram Keshari Pradhan, Debarati Chatterjee +2
Massive boson stars are self-gravitating configurations of self-interacting scalar fields and can be modeled by a massive scalar field with a quartic self-interaction potential. It…
Effects of Dark Matter on -mode oscillations of Neutron Stars
Swarnim Shirke, Bikram Keshari Pradhan, Debarati Chatterjee +2
The effect of dark matter (DM) on -mode oscillations in DM admixed neutron stars (NSs) is investigated in a comprehensive analysis with particular attention to the role of the n…
Post-Newtonian effects in compact binaries with a dark matter spike: A Lagrangian approach
Diego Montalvo, Adam Smith-Orlik, Saeed Rastgoo +3
We apply the Lagrangian method to study the post-Newtonian evolution of a compact binary system with environmental effects, including a dark matter spike, and obtain the resulting…
Binary systems in massive scalar-tensor theories: Next-to-leading order gravitational wave phase from effective field theory
Robin Fynn Diedrichs, Daniel Schmitt, Laura Sagunski
Neutron star binaries and their associated gravitational wave signal facilitate precision tests of General Relativity. Any deviation of the detected gravitational waveform from Gen…
Fermion Proca Stars: Vector Dark Matter Admixed Neutron Stars
Cédric Jockel, Laura Sagunski
Dark matter could accumulate around neutron stars in sufficient amounts to affect their global properties. In this work, we study the effect of a specific model for dark matter --…
Tidal Deformability of Fermion-Boson Stars: Neutron Stars Admixed with Ultra-Light Dark Matter
Robin Fynn Diedrichs, Niklas Becker, Cédric Jockel +3
In this work we investigate the tidal deformability of a neutron star admixed with dark matter, modeled as a massive, self-interacting, complex scalar field. We derive the equation…
Comparing Accretion Disks and Dark Matter Spikes in Intermediate Mass Ratio Inspirals
Niklas Becker, Laura Sagunski
Intermediate Mass Ratio Inspirals (IMRIs) will be observable with space-based gravitational wave detectors such as the Laser Interferometer Space Antenna (LISA). To this end, the e…
Circularization vs. Eccentrification in Intermediate Mass Ratio Inspirals inside Dark Matter Spikes
Niklas Becker, Laura Sagunski, Lukas Prinz +1
Inspirals of an Intermediate Mass Black Hole (IMBH) and a solar mass type object will be observable by space based gravitational wave detectors such as The Laser Interferometer Spa…
Neutron star mergers as a probe of modifications of general relativity with finite-range scalar forces
Laura Sagunski, Jun Zhang, Matthew C. Johnson +5
Observations of gravitational radiation from compact binary systems provide an unprecedented opportunity to test General Relativity in the strong field dynamical regime. In this pa…
