A heliogyro is a rotating solar sail with the reflecting surface divided into a number of long and slender blades, which are stiffened by a spin-induced centrifugal force. Each blade can rotate around its own longitudinal axis so as to change the pit

Descartes’ and Fermat's method allowed to define many geometrical forms, including circles, on the coordinate plane by means of the arithmetic equations and to make necessary analytical operations in order to solve many problems of theoretical and

The fundamental plane (FP) is the relation between the surface brightness (I), velocity dispersion (σ) and radius (R). The tilt of FP from the virial plane (R = σ2 I) not only tells the dynamical states of the system but also its formation and evol

In the eighteenth century and earlier, complex numbers were called imaginary numbers and were manipulated algebraically without giving them any geometric meaning. In the early nineteenth century the concept of the complex plane was formulated with th

In this Note, a configuration factor between a circle and the three coordinate directions is presented. This new factor brings considerable independence and versatility to radiative transfer analysis as it allows determining the radiative energy for

The standardized Brazilian disc test is revisited considering the disc-jaw complex as a system of two elastic bodies in contact. The aim of the study is to shed light on the conditions at the disc-jaw interface in an effort to quantify the length of

Open clusters (OCs) are important objects for stellar dynamics studies. The short survival timescale of OCs makes them closely related to the formation of Galactic field stars. We motivate to investigate the dynamical evolution of OCs on the aspect o
