We develop a simple model for computing planetary formation based on the core instability model for the gas accretion and the oligarchic growth regime for the accretion of the solid core. In this model several planets ca...

Context. Co-orbital objects, also known as Trojans, are celestial bodies that share a 1:1 mean motion resonance orbit with a planet. Many planets in our Solar System hold Trojans, yet none has been confirmed in exoplanet...

Context. Astronomical environments are governed by a complex interplay of physical processes, including gravitational dynamics, radiative transfer, stellar evolution, chemistry, and hydrodynamics. These processes span a ...

"Education, in and of itself, is neither irrelevant nor outmoded. However, the current need to educate a planetary citizenry under conditions relevant to the living context of our planet is palpable. A new education para...

Context: Binary systems with similar components are ideal laboratories that allow several physical processes to be tested, such as the possible chemical pattern imprinted by the planet formation process. Aims. We explore...

The secular approximation of the hierarchical three body systems has been proven to be very useful in addressing many astrophysical systems, from planets to stars to black holes. In such a system, two objects are on a ti...

Context. A growing number of white dwarfs (WDs) exhibit one or more signs of remnant planetary systems, including transits, infrared excesses, and atmospheric metal pollution. WD 1054-226 stands out for its unique, highl...

Food waste (FW) in collective catering settings remains a critical barrier to sustainable food systems, due to its magnitude and multidimensional negative impacts. Food waste reduction and prevention measures are often d...

The paper analyses the legally established practice of agriculture has been forced out of the urban environment as land value increases with higher population densities. It’s stated, that cities and surrounding urban e...

Introduction According to modern scholars (N. Maslova, B. Astafiev), one of the important reasons for the global planetary crisis, including modern educational system in particular, is violation of the conformity of natu...

Humanity is on a deeply unsustainable trajectory. We are exceeding planetary boundaries and unlikely to meet many international sustainable development goals and global environmental targets. Until recently, there was no...

In this paper we present a new mixed-variables symplectic tree code for planetesimal dynamics, which allows to use a very large number of particles in numerical simulations of planet disk interaction. Furthermore, we dis...
