Build-A-Planet Workshop: Planet Formation, One Bump at a Time Today's bite looks at how planets are formed in the "bumps" of protoplanetary disks.

A white protoplanetary disc at the centre of the picture takes up most of the frame. The elliptical cloud of dust and gas consists of some gaps creating a ring-like structure to the cloud. In one of the larger gaps/rings a little dot (a planet) is visible.

A very hungry planet! πŸͺ

What appears to be a ripple in space is actually a newborn planet, eating its way through its dusty cradle around a younger version of our Sun 🌞

And before anyone asks, the correct ranking of Paulaner sodas is:

With the #ALMA deadline approaching rapidly, did you know that you can easily create (sub-)mm images of your favorite DustPy model with RADMC-3D using the radiative transfer libraries of DustPyLib?
The latest release (v0.7.0) even contains a lightweight slab model. πŸ”­

Since numpy.distutils got removed (thanks NumPy devs πŸ™„) I had a hard time packing Fortran routines in my Python packages.

To save you some headaches here is a minimum working example of how you can do this.
