A very hungry planet! 🪐

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 🌞

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.

Exoplanet System

xkcd.com/3103/
Comic. [planets and astronomical bodies in various shapes with comments pointing to them] Typical Exoplanet System: Giant planet orbiting so close that it’s actually rolling on the star’s surface; Hot Jupiter; Mini Neptune; Planet that could be habitable, if there’s a form of life that hates water but loves acid and being on fire; Cold Jupiter; Potentially habitable void; Hot Mars; Planet that may actually be in the habitable zone, according to a very optimistic modeling paper by some desperate postdocs; There’s a pulsar here but it’s probably fine; A waterworld paradise with beautiful oceans and warm— Wait, no, we just got new measurements, it’s a hellish steam oven; Mini Pluto; Earthlike data artifact; Wet Saturn; Either a gas giant or a fist-sized rock, depending which calibration method you use; Faint dust cloud that will cause several papers to be retracted; Somehow this whole system is smaller than the orbit of Mercury?!; Planet whose surface may host conditions suitable for rocks

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. 🔭

Since numpy.distutils got removed (thanks NumPy devs 🙄) 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.

Über fehlende Diversität wurde ja schon vieles gesagt.

Aber was macht das eigentlich mit CDU-Wählern, wenn hier – egal was passiert – immer irgendwelche Hanseln aus Bayern mit am Tisch sitzen? Und erfahrungsgemäß auch selten die talentiertesten.
