This was posted to Mastodon by Dr. Alexandre Santerne. Just had a go and it looks really nice and smooth, and has few options to change the simulation parameters.

Do you know how #astronomers are hunting for #exoplanets ? Most of them are discovered with the transit and/or radial velocity techniques.

We developed at #LAM (#laboratoire d'#astrophysique de #Marseille) a web tool that simulate an #exoplanet and show you their photometric and radial velocity signals. Feel free to play with the parameters and see how they change the signals.

Astronomy is making fantastic new discoveries all the time, not just with space based telescopes but with ground based observatories too.

By harnessing the capabilities of the Gemini South telescope in Chile, astronomers have obtained the sharpest image ever of the star R136a1, the most massive known star in the universe. Their research challenges our understanding of the most massive stars and suggests that they may not be as massive as previously thought. 

This article explains more.

We are improving our knowledge and understanding all the time, with new telescopes both earth and space based due to come online over the next decade alone. This is probably a good time to start looking at studying astronomy and being part of something really exciting.

This looks like a really interesting paper, published on Oxford Academic [1], examining, what appears to be the unusual composition of Przybylski's star [2]. According to Wikipedia [3]* is in the “Southern constellation of Centaurus”

• See [4] for a better reference.
  

There seems to be quite a few heavier element detected.
