Saving Planetary Systems: Dead Zones & Planetary Migration [PDF]

The Astrophysical Journal, 2006
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.

Planetary mass function and planetary systems [PDF]

Monthly Notices of the Royal Astronomical Society, 2010
With planets orbiting stars, a planetary mass function should not be seen as a low-mass extension of the stellar mass function, but a proper formalism needs to take care of the fact that the statistical properties of planet populations are linked to the ...

Forming Different Planetary Systems [PDF]

Research in Astronomy and Astrophysics, 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 ...

Dusty Planetary Systems [PDF]

, 2012
Extensive photometric stellar surveys show that many main sequence stars show emission at infrared and longer wavelengths that is in excess of the stellar photosphere; this emission is thought to arise from circumstellar dust.

Research Progress on the Dynamic Characteristics of Planetary Gear Transmission in a Non-Inertial System

Machines, 2023
Planetary gear systems have many advantages over other gear systems. Previous studies on its dynamic characteristics mostly used Earth as the reference system, which is inconsistent with the actual working conditions of many planetary gear systems, such ...

The protoplanetary disc HD 163296 as observed by ALMA

Vietnam Journal of Science, Technology and Engineering, 2022
HD 163296 is one of the few protoplanetary discs displaying rings in the dust component. The present work uses ALMA observations of the 0.9 mm continuum emission, which have significantly better spatial resolution (~8 au) than previously available, to ...

Paleo‐Permeability Structure of the Crustal Section of the Samail Ophiolite Based on Automated Detection of Veins in X‐Ray CT Core Images From the Oman Drilling Project

Geochemistry, Geophysics, Geosystems, 2023
To assess the paleo‐permeability structure of oceanic crust, we used 3‐D X‐ray Computed Tomography (XCT) images to quantify the distribution and geometry of mineral veins in core samples from Oman Drilling Project Holes GT1A, GT2A, and GT3A, which ...

The Deuterium Isotopic Ratio of Water Released From the Martian Caps as Measured With TGO/NOMAD

Geophysical Research Letters, 2022
We report vertical profiles of water and D/H for one Martian year as measured with the TGO/NOMAD instrument. The observations were performed via solar occultation, providing water profiles up to ∼100 km and D/H up to ∼60 km, with a vertical resolution of
