We present our implementation of cohesion in the parallel N-body code pkdgrav in order to model small bodies that are not fully monolithic but that have at least some degree of cohesion. Small bodies ...
Simulating the D/H ratio of water formed in the early solar nebula
collapsing core solar nebula dust chemistry D/H ratio of water
2017/4/11
Our solar system originated from a protoplanetary disk about 4.6 billion years ago. We simulate the formation of this
disk by a three-stage model of the solar nebula (SN) which describes the hydrodyn...
Simulating the Common Envelope Phase of a Red Giant Using SPH and Uniform Grid Codes
Simulating Common Envelope Phase Red Giant Using SPH Uniform Grid Codes
2011/10/21
We use three-dimensional hydrodynamical simulations to study the rapid infall phase of the common envelope interaction of a red giant branch star of mass equal to 0.88 \msun and a companion star of ma...
From Bipolar to Elliptical: Simulating the Morphological Evolution of Planetary Nebulae
From Bipolar Elliptical: Simulating Morphological Evolution Planetary Nebulae
2011/9/27
The majority of Proto-planetary nebulae (PPN) are observed to have bipolar morphologies. The majority of mature PN are observed to have elliptical shapes. In this paper we address the evolution of PPN...
