Forming Different Planetary Systems

open access: yes, 2012
With the increasing number of detected exoplanet samples, the statistical properties of planetary systems have become much clearer. In this review, we summarize the major statistics that have been revealed mainly by radial velocity and transiting ...

AMD-stability and the classification of planetary systems [PDF]

open access: yes, 2017
We present here in full detail the evolution of the angular momentum deficit (AMD) during collisions as it was described in (Laskar, PRL,2000). Since then, the AMD has been revealed to be a key parameter for the understanding of the outcome of planetary ...

Formation, Orbital and Internal Evolutions of Young Planetary Systems [PDF]

open access: yesSpace Science Reviews, 2016
The growing body of observational data on extrasolar planets and protoplanetary disks has stimulated intense research on planet formation and evolution in the past few years. The extremely diverse, sometimes unexpected physical and orbital characteristics of exoplanets lead to frequent updates on the mainstream scenarios for planet formation and ...

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges

open access: yesAdvanced Functional Materials, EarlyView.
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

Planetary Formation Constrained by Collisions between Millimeter-sized Lunar Particles and Lunar Surface from Chang’E-4 Mission

open access: yesThe Astrophysical Journal
Exploring low-velocity collisions is crucial for unraveling intricate processes in planetary formation, particularly the bouncing barrier that impedes the aggregation of dust into sizable planetesimals.

Asteroid flux towards circumprimary habitable zones in binary star systems: I. Statistical Overview

open access: yes, 2015
So far, multiple stellar systems harbor more than 130 extra solar planets. Dynamical simulations show that the outcome of planetary formation process can lead to various planetary architecture (i.e.

Architectures of planetary systems and implications for their formation [PDF]

open access: yesProceedings of the National Academy of Sciences, 2014
SignificancePrior to the discovery of exoplanets, astronomers fine tuned theories of planet formation to explain detailed properties of the solar system. The discovery of exoplanets has significantly increased our appreciation for the diversity of planetary systems in nature.

Dual‐Programmable Architected Magnetic Soft Materials: Tuning Mechano–Electric Responses by Inverse Design

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Materials that can deform, sense, and autonomously generate power in response to wireless magnetic fields, through both magnetic‐actuated shape transformation and charge generation, are an emerging focus in advanced functional materials research.

Streaming Torque with Turbulent Diffusion

open access: yesThe Astrophysical Journal
Fast type I migration of (proto)planets poses a challenging problem for the core accretion formation scenario. We found that the dust-induced “Streaming Torque” (ST) may slow down or even reverse the planet migration in Q. Hou & C. Yu.

When and why formation of large bodies in circumstellar discs could take place?

open access: yesEPJ Web of Conferences, 2013
We outlined the scenario of the planetary system formation, where large bodies are formed on the stage of massive discs. On this stage the whole of factors: chemical composition, chemical catalytic reactions, the disc self- gravitation, the increased ...
