bennu

Code and display software used for this paper on Bennu
https://arxiv.org/abs/1804.02058

The mass-spring model code is built upon the N-body code rebound, see https://github.com/hannorein/rebound

The Bennu code example is in myexamples/bennu2/ and uses the Bennu shape model by Nolan, M.C., et al. 2013, Shape model and surface properties of the OSIRIS-REx target Asteroid (101955) Bennu from radar and light-curve observations. Icarus 226, 629-640.

The bennu2 directory also contains parameter files used in the paper.

Associated jupyter notebooks for looking at outputs is in myexamples/pylab/
(though I tend to move code outputs into subdirectories before running it). The bennu_spec notebook lets you look at the spectrum of normal mode excitation.

Slightly edited rebound code is in src/

Spring routines (not part of rebound) are in src_spring/
