Wave dynamics and star formation in Taurus [PDF]
Symposium - International Astronomical Union, 1991 The mechanism underlying the formation of cores and larger scale structures in molecular clouds must play a fundamental role in the physics of star formation since young stellar objects are usually found within or very near cores (Myers et al 1987, Beichman et al 1986).

Photons generated by gravitational waves in the near-zone of a neutron star
Nuclear Physics B, 2022 When a gravitational wave or a graviton travels through an electric or magnetic background, it could convert into a photon with some probability. In this paper, a dipole magnetic field is considered as this kind of background in both the Minkowski ...

Wave chaos in rapidly rotating stars [PDF]
Physical Review E, 2008 Effects of rapid stellar rotation on acoustic oscillation modes are poorly understood. We study the dynamics of acoustic rays in rotating polytropic stars and show using quantum chaos concepts that the eigenfrequency spectrum is a superposition of regular frequency patterns and an irregular frequency subset respectively associated with near-integrable ...

Monster Radiative Shocks in the Perturbed Magnetospheres of Neutron Stars
The Astrophysical Journal, 2023 Magnetospheres of neutron stars can be perturbed by star quakes, interaction in a binary system, or sudden collapse of the star. The perturbations are typically in the kilohertz band and excite magnetohydrodynamic waves.

Optical detection of the density-wave instability in the kagome metal KV3Sb5
npj Quantum Materials, 2022 Coexisting density-wave and superconducting states along with the large anomalous Hall effect in the absence of local magnetism remain intriguing and enigmatic features of the AV3Sb5 kagome metals (A = K, Rb, Cs).

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.

Transmuted gravity wave signals from primordial black holes
Physics Letters B, 2018 Primordial black holes (PBHs) interacting with stars in binaries lead to a new class of gravity wave signatures that we explore. A small 10−16–10−7M⊙ PBH captured by a neutron star or a white dwarf will eventually consume the host.

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.
