The Survival Rate of Ejected Terrestrial Planets with Moons [PDF]

open access: yes, 2007
During planet formation, a gas giant will interact with smaller protoplanets that stray within its sphere of gravitational influence. We investigate the outcome of interactions between gas giants and terrestrial-sized protoplanets with lunar-sized ...

Detection of Laplace-resonant three-planet systems from transit timing variations [PDF]

open access: yes, 2013
Transit timing variations (TTVs) are useful to constrain the existence of perturbing planets, especially in resonant systems where the variations are strongly enhanced.

Direct imaging of exoplanets: Legacy and prospects

open access: yesComptes Rendus. Physique, 2023
Understanding how giant and terrestrial planets form and evolve, what is their internal structure and that of their atmosphere, represents one of the major challenges of modern astronomy, which is directly connected to the ultimate search for life at the

Investigation of the Sudden Solar Ionospheric Disturbance using Radio Telescope [PDF]

open access: yesEPJ Web of Conferences, 2020
Low-frequency radio telescopes are cheap and useful devices for the investigation of terrestrial and extra-terrestrial emissions. These emissions come either from the Sun and the planet Jupiter to terrestrial emissions.

The interiors of the terrestrial planets

open access: yesJournal of Geophysical Research, 1965
Conclusions regarding the internal constitution of the terrestrial planets are dependent on the assumption as to the nature of the earth's core. It has previously been supposed that if the terrestrial planets, Earth, Venus, and Mars, are of similar composition the material of the core must represent a phase change, but if the core material is ...

Are There Terrestrial Planets Lurking in the Outer Solar System?

open access: yesThe Astrophysical Journal Letters, 2023
Motivated by recent measurements of the free-floating-planet mass function at terrestrial masses, we consider the possibility that the solar system may have captured a terrestrial planet early in its history.

Einstein’s Problem

open access: yesJournal of World-Systems Research, 2023
This paper focuses upon the human migratory trajectory from eons on planet Earth to slowly moving out into orbital space and whether world-systems theory must craft new theoretical frames to grasp the possible problems arising from the existence of a ...

Formation of telluric planets and the origin of terrestrial water

open access: yesBIO Web of Conferences, 2014
Simulations of planet formation have failed to reproduce Mars’ small mass (compared with Earth) for 20 years. Here I will present a solution to the Mars problem that invokes large-scale migration of Jupiter and Saturn while they were still embedded in ...

Microplastic Pollution in Terrestrial Ecosystems and Its Interaction with Other Soil Pollutants: A Potential Threat to Soil Ecosystem Sustainability

open access: yesResources, 2023
The production and disposal of plastics have become significant concerns for the sustainability of the planet. During the past 75 years, around 80% of plastic waste has either ended up in landfills or been released into the environment.
