Searches for continuous-wave gravitational radiation
Living Reviews in Relativity, 2023 Now that detection of gravitational-wave signals from the coalescence of extra-galactic compact binary star mergers has become nearly routine, it is intriguing to consider other potential gravitational-wave signatures.

Observation of Star-Shaped Surface Gravity Waves [PDF]
Physical Review Letters, 2013 We report a new type of standing gravity wave of large amplitude, having alternatively the shape of a star and of a polygon. This wave is observed by means of a laboratory experiment by vertically vibrating a tank. The symmetry of the star (i.e., the number of branches) is independent of the container form and size, and can be changed according to the ...

Solution to the Dirichlet Problem of the Wave Equation on a Star Graph
Mathematics, 2023 In this paper, the solution to the Dirichlet problem for the wave equation on the star graph is constructed. To begin, we solve the boundary value problem on the interval (on one edge of the graph).

Detecting the Hadron-Quark Phase Transition with Gravitational Waves
Universe, 2019 The long-awaited detection of a gravitational wave from the merger of a binary neutron star in August 2017 (GW170817) marks the beginning of the new field of multi-messenger gravitational wave astronomy.

R-Mode Oscillations and Spindown of Young Rotating Magnetic Neutron Stars [PDF]
, 2000 Recent work has shown that a young, rapidly rotating neutron star loses angular momentum to gravitational waves generated by unstable r-mode oscillations.

Measuring Neutron-Star Properties via Gravitational Waves from Neutron-Star Mergers [PDF]
Physical Review Letters, 2012 We demonstrate by a large set of merger simulations for symmetric binary neutron stars (NSs) that there is a tight correlation between the frequency peak of the postmerger gravitational-wave (GW) emission and the physical properties of the nuclear equation of state (EoS), e.g., expressed by the radius of the maximum-mass Tolman-Oppenheimer-Volkhoff ...

A Brief Overview of Black Hole-Neutron Star Mergers
Frontiers in Astronomy and Space Sciences, 2020 Of the three main types of binaries detectable through ground-based gravitational wave observations, black hole-neutron star (BHNS) mergers remain the most elusive.

Gravitational Waves from Low-Mass X-ray Binaries: a Status Report [PDF]
, 2000 We summarize the observations of the spin periods of rapidly accreting neutron stars. If gravitational radiation is responsible for balancing the accretion torque at the observed spin frequencies of ~300 Hz, then the brightest of these systems make ...

Initial data for black hole-neutron star binaries, with rotating stars [PDF]
, 2016 The coalescence of a neutron star with a black hole is a primary science target of ground-based gravitational wave detectors. Constraining or measuring the neutron star spin directly from gravitational wave observations requires knowledge of the ...

Possible direct method to determine the radius of a star from the spectrum of gravitational wave signals [PDF]
, 2000 We computed the spectrum of gravitational waves from a dust disk star of radius R inspiraling into a Kerr black hole of mass M and specific angular momentum a. We found that when R is much larger than the wave length of the quasinormal mode, the spectrum
