On a new type of solving procedure for Laplace tidal equation

Sergey V. Ershkov, Roman V. Shamin

In this paper, we present a new approach for solving Laplace tidal equations (LTE) which was formulated first in [S.V.Ershkov, A Riccati-type solution of Euler-Poisson equations of…

Galileon-like vector fields

Pavel Petrov

We construct simple Lagrangians of vector fields which involve second derivatives, but nevertheless lead to second order field equations. These vector fields are, therefore, analog…

Radial trends in Galactic globular clusters and their possible origin

Valery V. Kravtsov

The relaxation time at the half-mass radius of Galactic globular clusters (GGCs) is typically within a few Gyr. Hence, the majority of GGCs are expected to be well relaxed systems,…

Properties of Kepler Stars with the Most Powerful Flares

M. M. Katsova, B. A. Nizamov

We analyze physical characteristics of late-type stars wherein the Kepler mission registered superflares. We use the revised stellar fundamental parameters, i.e. effective temperat…

Properties of at small opening angles in collisions with the ATLAS detector at TeV

ATLAS Collaboration

The fragmentation of high-energy gluons at small opening angles is largely unconstrained by present measurements. Gluon splitting to -quark pairs is a unique probe into the prop…
