Formation and transformation of the 3:1 mean-motion resonance in 55 Cancri System
, 2007 We report in this paper the numerical simulations of the capture into the 3:1 mean-motion resonance between the planet b and c in the 55 Cancri system. The results show that this resonance can be obtained by a differential planetary migration.

The Anatomical Record, EarlyView.Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.

Growth and evolution of satellites in a Jovian massive disc
, 2017 The formation of satellite systems in circum-planetary discs is considered to be similar to the formation of rocky planets in a proto-planetary disc, especially Super-Earths.

Period ratios in multi-planetary systems discovered by Kepler are consistent with planet migration
, 2012 The Kepler planet candidates are an interesting testbed for planet formation scenarios. We present results from N-body simulations of multi-planetary systems that resemble those observed by Kepler.

Batteries &Supercaps, EarlyView.The effect of the blending procedure on the C−S suspension and therefore, on the Li−S battery performance is investigated. By comparing a common laboratory blender with a high shear mixing device, the higher shear forces result in a lower porosity and improved homogeneity of the electrode leading to enhanced cycle life, especially in multi‐layered ...

The PFS View of TOI-677 b: A Spin–Orbit Aligned Warm Jupiter in a Dynamically Hot System
The Astronomical JournalTOI-677 b is part of an emerging class of “tidally detached” gas giants ( a / R _⋆ ≳ 11) that exhibit large orbital eccentricities and yet low stellar obliquities. Such sources pose a challenge for models of giant planet formation, which must account for

On the formation time scale and core masses of gas giant planets
, 2003 Numerical simulations show that the migration of growing planetary cores may be dominated by turbulent fluctuations in the protoplanetary disk, rather than by any mean property of the flow.

Streaming Torque in Dust–Gas Coupled Protoplanetary Disks
The Astrophysical JournalWe investigate the migration of low-mass protoplanets embedded in dust–gas coupled protoplanetary disks. Linear calculations are performed with respect to the Nakagawa–Sekiya–Hayashi (NSH) equilibrium within a shearing sheet. We find that the dusty quasi-
