Dynamical Outcomes of Planet‐Planet Scattering [PDF]
Observations in the past decade have revealed extrasolar planets with a wide range of orbital semimajor axes and eccentricities. Based on the present understanding of planet formation via core accretion and oligarchic growth, we expect that giant planets often form in closely packed configurations.

Ontosonographic Maps: Toward a Theoretization of Soundscape Forms in the Anthropocene Epoch
This paper deals with the ways in which it is possible to conceptualize and map forms of soundscape in the epoch of the Anthropocene. After humans became a geological force, which is a role that used to be reserved for the planet itself, one can pose the

A new family of planets? “Ocean-Planets” [PDF]
A new family of planets is considered which is between rochy terrestrial planets and gaseous giant ones: "Ocean-Planets". We present the possible formation, composition and internal models of these putative planets, including that of their ocean, as well as their possible Exobiology interest.

The Gemini Planet Imager Exoplanet Survey: Giant Planet and Brown Dwarf Demographics from 10 to 100 au [PDF]
We present a statistical analysis of the first 300 stars observed by the Gemini Planet Imager Exoplanet Survey. This subsample includes six detected planets and three brown dwarfs; from these detections and our contrast curves we infer the underlying ...

Water vapour in the atmosphere of the habitable-zone eight-Earth-mass planet K2-18 b [PDF]
In the past decade, observations from space and the ground have found water to be the most abundant molecular species, after hydrogen, in the atmospheres of hot, gaseous extrasolar planets1–5. Being the main molecular carrier of oxygen, water is a tracer

Specific Analysis of Web Camera and High Resolution Planetary Imaging [PDF]
Web camera is usually used for video communication between PC, it has small sensing area, cannot using long exposure application, so that is insufficient for astronomical application.

A giant planet candidate transiting a white dwarf [PDF]
Astronomers have discovered thousands of planets outside the Solar System1, most of which orbit stars that will eventually evolve into red giants and then into white dwarfs.
