Performances of Planetary Magnetorheological Transmission Devices

open access: yesFrontiers in Materials, 2022
Magnetorheological transmission devices (MRTDs) are a type of power transmission device using magnetorheological fluids (MRFs) as the transmission medium, which have the advantages of rapid response and continuously adjustable output performances.

Planetary Internal Structures [PDF]

open access: yes, 2014
This chapter reviews the most recent advancements on the topic of terrestrial and giant planet interiors, including Solar System and extrasolar objects. Starting from an observed mass-radius diagram for known planets in the Universe, we will discuss the various types of planets appearing in this diagram and describe internal structures for each type ...

RETRACTED: Redox Evolution of the Crystallizing Terrestrial Magma Ocean and Its Influence on the Outgassed Atmosphere

open access: yesThe Planetary Science Journal, 2023
Magma oceans (MOs) are episodes of large-scale melting of the mantle of terrestrial planets. The energy delivered by the Moon-forming impact induced a deep MO on the young Earth, corresponding to the last episode of core-mantle equilibration.

The Temperature Structure of Dusty Planetary Nebulae [PDF]

open access: yesSymposium - International Astronomical Union, 2001
We have computed photoionization models of planetary nebulae containing dust. Photoelectric heating by small grains has an important effects on the temperature structure of the nebulae and could solve a number of problems that have found no satisfactory solution so far.

Value Gaps in the Planetary Matrix of the World Community as a Limitrophe of War and Peace [PDF]

open access: yes, 2018
The article describes the problem of spontaneous transformation of the planetary matrix of the social world, moving from the cell to the network structure, resulting not only in the changes of the world system of the planetary community, the shapes of ...

Morphological Structures of Planetary Nebulae [PDF]

open access: yesPublications of the Astronomical Society of Australia, 2010
AbstractSince various structural components of planetary nebulae (PN) manifest themselves differently, a combination of optical, infrared, submillimetre and radio techniques is needed to derive a complete picture of planetary nebulae. The effects of projection can also make derivation of the true 3-D structure difficult.

Dynamical Measurements of the Interior Structure of Exoplanets [PDF]

open access: yes, 2013
Giant gaseous planets often reside on orbits in sufficient proximity to their host stars for the planetary quadrupole gravitational field to become non-negligible. In presence of an additional planetary companion, a precise characterization of the system'

The Effects of Rotation Rate on Deep Convection in Giant Planets with Small Solid Cores [PDF]

open access: yes, 2006
We study how the pattern of thermal convection and differential rotation in the interior of a giant gaseous planet is affected by the presence of a small solid core as a function of the planetary rotation rate.

Composition of Massive Giant Planets [PDF]

open access: yes, 2010
The two current models for giant planet formation are core accretion and disk instability. We discuss the core masses and overall planetary enrichment in heavy elements predicted by the two formation models, and show that both models could lead to a ...
