Altitude-Dependent Near-Source Spectral Filtering of Meteor Infrasound Above 80 km and Consequences for Period-Based Energy Estimates
Elizabeth A. Silber, Igor P. Chunchuzov, Oleg E. Popov +1
Infrasound signal period is widely used as a proxy for source energy in bolide studies, but the reliability of period-yield relations for small, high-altitude regional meteors has…
Multi-Arrival Infrasound from Meteoroids: Fragmentation Signatures versus Propagation Effects in a Fine-Scale Layered Atmosphere
Igor P. Chunchuzov, Oleg E. Popov, Elizabeth A. Silber +1
Infrasonic signatures of meteoroid fragmentation are frequently ambiguous: do multiple arrivals signify a complex breakup or merely the distorting effects of a layered atmosphere?…
Effect of a Fine-Scale Layered Structure of the Atmosphere on Infrasound Signals from Fragmenting Meteoroids
Igor P. Chunchuzov, Oleg E. Popov, Elizabeth A. Silber +1
We investigate the influence of a fine-scale (FS) layered structure in the atmosphere on the propagation of infrasound signals generated by fragmenting meteoroids. Using a pseudo-d…
Linear instability of plane Couette and Poiseuille flows
Sergey G. Chefranov, Alexander G. Chefranov
It is shown that linear instability of plane Couette flow can take place even at finite Reynolds numbers which meets with known experimental data. This new result of the linear the…
Four-thirds law of energy and magnetic helicity in electron and Hall magnetohydrodynamic fluids
Yanqing Wang, Otto Chkhetiani
In this paper, by exploiting the feature of the Hall term, we establish some local version four-thirds laws for the dissipation rates of energy and magnetic helicity in both electr…
Hot Spots in Sgr A* Accretion Disk: Hydrodynamic Insights
E. P. Tito, V. P. Goncharov, V. I. Pavlov
The recent image of our galaxy's supermassive black hole Sgr A* derived from the 7 April 2017 data of the Event Horizon Telescope Collaboration shows multiple hot spots in its accr…
Investigating the dynamics of point helical vortices on a rotating sphere to model tropical cyclones
Sergey G. Cherfanov, Igor I. Mokhov, Alexander G. Chefranov
A general exact weak solution to the nonlinear equation of the conservation of the absolute vorticity in a thin layer of an incompressible medium on a rotating sphere is proposed.…
Dynamics of nanosecond laser pulse propagation and of associated instabilities in a magnetized underdense plasma
W. Yao, A. Higginson, J. -R. Marquès +19
The propagation and energy coupling of intense laser beams in plasmas are critical issues in laser-driven inertial confinement fusion. Applying magnetic fields to such a setup has…
Characterization and performance of the Apollon Short-Focal-Area facility following its commissioning at 1 PW level
K. Burdonov, A. Fazzini, V. Lelasseux +45
We present the results of the first commissioning phase of the ``short focal length'' area (SFA) of the Apollon laser facility (located in Saclay, France), which was performed with…
On discretizing sea-ice dynamics on triangular meshes using vertex, cell or edge velocities
S. Danilov, C. Mehlmann, V. Fofonova
Discretization of the equations of Viscous Plastic and Elastic Viscous Plastic (EVP) sea ice dynamics on triangular meshes can be done by placing discrete velocities at vertices, c…
Characterization of the stability and dynamics of a laser-produced plasma expanding across strong magnetic field
Weipeng Yao, Julien Capitaine, Benjamin Khiar +5
Magnetized laser-produced plasmas are central to many new studies in laboratory astrophysics, inertial confinement fusion, and industrial applications. Here we present the results…

The impact of the short-range interaction on the resonances occurrence in the anisotropic dipolar scattering in a plane was numerically investigated for the arbitrarily oriented di…
Point vortices dynamics on a rotating sphere and modeling of global atmospheric vortices interaction
Igor I. Mokhov, Sergey G. Chefranov, Alexander G. Chefranov
It is shown that the hydrodynamics equations for a thin spherical liquid layer are satisfied by the stream function of a pair of antipodal vortices-APV, in contrast to the stream f…
