A reversible N-body integrator with JANUS
Crowned the god of doorway and passages in Roman mythology, Janus had access to the future and the past. In modern times, he is reincarnated into a secret code that turns back time, in computer simulations.
Breaking Planet Chains and Cracking the Kepler Dichotomy
Why can’t more exoplanet systems be like TRAPPIST-1? Why do so many Kepler systems have only one transiting planet? Today’s paper tries to answer both questions.
Teaching Computers How Galaxies Form
After learning about galaxy formation, computers can imitate millions of hours of calculations in just a few minutes.
Planet IX
Get ready to come up with a new mnemonic for the planets. The orbits of distant objects suggest that there may be something lurking in the outer Solar System as big as Neptune!
UR #16: Star Cluster Evolution
This month’s undergraduate research post features a student who created N-body simulations of star clusters. Read on to find out what she learned about the clusters’ evolution!
Tidal tails of dwarf galaxies on different orbits around the Milky Way
A phenomenological series of simulations of dwarf galaxies placed on different orbits around a Milky Way-like galaxy, in order to learn about the properties (and observability) of tidal tails in dwarf galaxies around our Milky Way.
