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

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

1. Spezi
2. Zitrone
3. Orange

Protoplanetary disk HD 163296 from Andrews et al. (2018) using Paulaner Colormaps.

Is it incredibly useful? Probably not.
Do you need it? Hell, yeah!

Three example of the Paulaner colormaps on the protoplanetary disk HD 163296 showing an almost axisymmetric disk with distinct rings and gaps substructures and a small vortex-like feature in the Southwest direction. Left: Spezi color scheme going from purple via red to yellow. Center: Orange color scheme going from red to yellow. Right: Lemon color scheme going from green to yellow.

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. 🔭

If anything in this repository is inefficient, not exactly "best practice", or simply plain wrong, I appreciate any input on how to improve it.

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.

Dann hätte die CSU vermutlich keinen der vier Münchner Wahlkreise gewonnen und wir könnten uns diese ganze Diskussion um verfallene Direktmandate sparen.

Sebastian Stammler @stammler.bsky.social · Feb 26

Vorschlag: Direktmandat nur bei >50 %. Ansonsten zweiter Wahlgang mit Stichwahl. Alternativ: Ein Wahlgang mit Ranked Voting.
