Planetary mass function and planetary systems [PDF]

open access: yesMonthly 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 ...

Theory of planet formation and comparison with observation

open access: yesEPJ Web of Conferences, 2011
The planetary mass-radius diagram is an observational result of central importance to understand planet formation. We present an updated version of our planet formation model based on the core accretion paradigm which allows us to calculate planetary ...

Dynamic changes in optical and chemical properties of tar ball aerosols by atmospheric photochemical aging [PDF]

open access: yesAtmospheric Chemistry and Physics, 2019
Following wood pyrolysis, tar ball aerosols were laboratory generated from wood tar separated into polar and nonpolar phases. Chemical information of fresh tar balls was obtained from a high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS)

Development and prospect of planetary optical remote sensing at Lenghu

open access: yes地球与行星物理论评, 2021
Planetary science is the one among the frontiers of science in the world and also is one of the key components of the development strategy of science and technology in China, which reflects the state of national natural science and the comprehensive ...

Evidence for benthic–pelagic food web coupling and carbon export from California margin bamboo coral archives [PDF]

open access: yesBiogeosciences, 2014
Deep-sea bamboo corals (order Gorgonacea, family Isididae) are known to record changes in water mass chemistry over decades to centuries. These corals are composed of a two-part skeleton of calcite internodes segmented by gorgonin organic nodes.

On the Potential of Silicon as a Building Block for Life

open access: yesLife, 2020
Despite more than one hundred years of work on organosilicon chemistry, the basis for the plausibility of silicon-based life has never been systematically addressed nor objectively reviewed.

A Remote Sensing Perspective on Mass Wasting in Contrasting Planetary Environments: Cases of the Moon and Ceres

open access: yesRemote Sensing, 2022
Mass wasting, as one of the most significant geomorphological processes, contributes immensely to planetary landscape evolution. The frequency and diversity of mass wasting features on any planetary body also put engineering constraints on its robotic ...

Planetary mass–radius relations across the galaxy [PDF]

open access: yesAstronomy & Astrophysics, 2020
Context. Planet formation theory suggests that planet bulk compositions are likely to reflect the chemical abundance ratios of their host star’s photosphere. Variations in the abundance of particular chemical species in stellar photospheres between different galactic stellar populations demonstrate that there are differences among the expected solid ...

Size-Resolved Community Structure of Bacteria and Fungi Transported by Dust in the Middle East

open access: yesFrontiers in Microbiology, 2021
The atmosphere plays an important role in transporting microorganisms on a global scale, yet the processes affecting the composition of the airborne microbiome, the aerobiome, are not fully outlined. Here we present the community compositions of bacteria

Isotopic evolution of planetary crusts by hypervelocity impacts evidenced by Fe in microtektites

open access: yesNature Communications, 2021
Fe isotopic composition of the distal ejecta of a terrestrial impact crater records both evaporation and condensation, refining the nature of the isotopic fractionation taking place during hypervelocity impacts in the Solar System.
