Post-main-sequence planetary system evolution [PDF]
Royal Society Open Science, 2016 The fates of planetary systems provide unassailable insights into their formation and represent rich cross-disciplinary dynamical laboratories. Mounting observations of post-main-sequence planetary systems necessitate a complementary level of theoretical

Excitation and Propagation of Eccentricity Disturbances in Planetary Systems [PDF]
, 2004 The high eccentricities of the known extrasolar planets remain largely unexplained. We explore the possibility that eccentricities are excited in the outer parts of an extended planetary disk by encounters with stars passing at a few hundreds of AU ...

Earth-like Habitats in Planetary Systems [PDF]
, 2014 Understanding the concept of habitability is related to an evolutionary knowledge of the particular planet-in-question. Additional indications so-called "systemic aspects" of the planetary system as a whole governs a particular planet's claim on ...

PARAMETER OPTIMIZATION FOR A THERMAL SIMULATION OF AN URBAN AREA [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023 Urban heat island (UHI) phenomenon is a significant challenge in urban planning, and accurate temperature predictions are crucial for effective decision-making. The choice of material parameters is crucial to simulate a realistic temperature distribution

Saving Planetary Systems: Dead Zones and Planetary Migration [PDF]
The Astrophysical Journal, 2007 The tidal interaction between a disk and a planet leads to the planet's migration. A long-standing question regarding this mechanism is how to stop the migration before planets plunge into their central stars. In this paper, we propose a new, simple mechanism to significantly slow down planet migration, and test the possibility by using a hybrid ...

On Populism, Planets, and Why Concepts Should Precede Definitions and Theory-Seeking
Sociologica, 2019 Despite its remarkable growth in recent years, the study of populism has long suffered from the lack of a comprehensive theory about its causes, development, and outcomes.

A new paradigm of governance for a carbon-pricing system [PDF]
, 2016 Throughout its life, the United Nations has played a pioneering role in the world of ideas. COP21 – also known as Paris 2015 – shows the path for the United Nations to establish a new governance that will enforce the compliance of a new planetary carbon ...

Stability and Formation of the Resonant System HD 73526 [PDF]
, 2007 Based on radial velocity measurements it has been found recently that the two giant planets detected around the star HD 73526 are in 2:1 resonance. However, as our numerical integration shows, the derived orbital data for this system result in chaotic ...

The record‐breaking heat wave of June 2019 in Central Europe
Atmospheric Science Letters, 2020 After being hit by several devastating heat waves in recent years, Europe experienced an exceptionally hot June in 2019 again. This June is the hottest one on record over Central Europe both in a monthly‐mean sense and in terms of the number of extremely
