Overview of this book

Jupyter has garnered a strong interest in the data science community of late, as it makes common data processing and analysis tasks much simpler. This book is for data science professionals who want to master various tasks related to Jupyter to create efficient, easy-to-share, scientific applications. The book starts with recipes on installing and running the Jupyter Notebook system on various platforms and configuring the various packages that can be used with it. You will then see how you can implement different programming languages and frameworks, such as Python, R, Julia, JavaScript, Scala, and Spark on your Jupyter Notebook. This book contains intuitive recipes on building interactive widgets to manipulate and visualize data in real time, sharing your code, creating a multi-user environment, and organizing your notebook. You will then get hands-on experience with Jupyter Labs, microservices, and deploying them on the web. By the end of this book, you will have taken your knowledge of Jupyter to the next level to perform all key tasks associated with it.

Using a complex orbit of multiple objects


The simulation scenario allows for easily adding more objects with varied orbit patterns.

How to do it...

We can use a script like this:

import rebound

# setup simulation
sim = rebound.Simulation()
sim.getWidget()

# add star
sim.add(m=1)

# add ten 'planets'
for i in range(10):
 sim.add(m=1e-3, a=0.4+0.1*i, inc=0.03*i, omega=5.*i)

# center all particles
sim.move_to_com()

# advance the simulation
sim.integrate(500)

# get our final display on screen
fig = rebound.OrbitPlot(sim)
fig

This results in a display like:

How it works...

Just as with the simpler case, we start a simulation. Then, in this case, we add a couple of objects. Each of the objects has a complex orbit about the star. We advance the clock by hundreds of cycles with sim.integrate(500) to gather a complete picture, and we display the results.
