Oligarchic planetesimal accretion and giant planet formation II [PDF]

open access: yes, 2009
The equation of state calculated by Saumon and collaborators has been adopted in most core-accretion simulations of giant-planet formation performed to date.

Giant Planet Occurrence in the Stellar Mass-Metallicity Plane [PDF]

open access: yes, 2010
Correlations between stellar properties and the occurrence rate of exoplanets can be used to inform the target selection of future planet search efforts and provide valuable clues about the planet formation process.

Rotary-Percussive Ultrasonic Drill: An Effective Subsurface Penetrating Tool for Minor Planet Exploration

open access: yesIEEE Access, 2018
Compared with conventional drill, an ultrasonic drill can break into rocks under lower weight on bit and lower power, which is more suitable to sample in low gravity environment for deep-space exploration. However, the ultrasonic drill cannot remove rock

Two drastically different climate states on an Earth-like terra-planet [PDF]

open access: yesEarth System Dynamics, 2018
We study an Earth-like terra-planet (water-limited terrestrial planet) with an overland recycling mechanism bringing fresh water back from the high latitudes to the low latitudes.

Jupiter - friend or foe? II: the Centaurs [PDF]

open access: yes, 2009
It has long been assumed that the planet Jupiter acts as a giant shield, significantly lowering the impact rate of minor bodies upon the Earth, and thus enabling the development and evolution of life in a collisional environment which is not overly ...

Orbits of the Asteroids Discovered at the Molėtai Observatory in 2000–2004

open access: yesOpen Astronomy, 2014
The paper presents statistics of the asteroids observed and discovered at the Molėtai Observatory, Lithuania in 2000–2004 within the project for astrometric observations of the near-Earth objects (NEOs), the main belt asteroids and comets.

A Survey for Massive Giant Planets in Debris Disks with Evacuated Inner Cavities [PDF]

open access: yes, 2007
The commonality of collisionally replenished debris around main sequence stars suggests that minor bodies are frequent around Sun-like stars. Whether or not debris disks in general are accompanied by planets is yet unknown, but debris disks with large ...

Misaligned Rings Around Minor Planets with Moons

open access: yesUniverse
Recent observations have confirmed the existence of rings around minor bodies in the outer solar system. These objects may possess satellites as well. Here, we analytically investigate the interaction between such rings and satellites.
