Trickle-Down The Solution The Planetary Core Formation
2017/12/19
Scientists have long pondered how rocky bodies in the solar system—including our own Earth—got their metal cores. According to research conducted by The University of Texas at Austin, evidence points ...

Research by Rice University Earth scientists suggests that virtually all of Earth’s life-giving carbon could have come from a collision about 4.4 billion years ago between Earth and an embryonic plane...
N-body simulations of cohesion in dense planetary rings:A study of cohesion parameters
Planetary rings Saturn, Rings Tides, Solid body Ices, Mechanical properties Collisional physics
2015/12/25
We present results from a large suite of simulations of Saturn’s dense A and B rings using a new model of particle sticking in local simulations (Perrine, R.P., Richardson, D.C., Scheeres, D.J. [2011]...
A numerical model of cohesion in planetary rings
Planetary rings Saturn, Rings Rotational dynamics Tides, Solid body Ices, Mechanical properties Collisional physics
2015/12/25
We present a numerical method that incorporates particle sticking in simulations using the N-body code pkdgrav to study motions in a local rotating frame, such as a patch of a planetary ring. Particle...

celestial mechanics stellar dynamics E minor planets asteroids
2015/12/25
Until recently, most asteroids were thought to be solid bodies whose shapes were determined largely by collisions with other asteroids. Recent work by Burns and others has shown that many asteroids ma...
SwRI scientists think “planetary pebbles” were the building blocks for the largest planets
SwRI scientists planetary pebbles building blocks largest planets
2015/9/9
Researchers at Southwest Research Institute (SwRI) and Queen’s University in Canada have unraveled the mystery of how Jupiter and Saturn likely formed. This discovery, which changes our view of how al...
