Congrats! I wish you all the best 🥰

Thanks 🙂! Do you mean at 7.5 micron? Those two are Hydrogen lines from the Pfund and Humphreys series.

This is our logo! It shows Xué, the god of the Sun in the Muisca culture, surrounded by a proto-planetary disk. One of its arms is the actual #JWST MIRI spectrum of XUE1! Thanks to Maria Cristina Fortuna for the logo and the beautiful illustration!

We are now analysing the rest of our observations in order to understand how common is XUE1 It is a very exciting time to be an astronomer! You can read the paper here:

XUE stands for eXtreme UV Environments and the collaboration is formed by more than 30 scientists around the world. Xue is also the name of the god of the Sun in the Muisca culture 🇨🇴🌞!

We report on the discovery of water and other molecules in the terrestrial forming zone of XUE1, near one of the most massive stars in the Galaxy! We show that there are favourable conditions to form Earth-like planets and the ingredients for life even in the harshest environments in our Galaxy 🔭🌌!

Qué bueno, Jorge!! Me alegra por ti 😊

I agree! it was the nicest it could have been for the last day before the JWST deadline 😊

I was! Most of the day making Newton disks with our younger visitors 🌈 🔭. I hope you enjoyed your day 🙂

This is a great step to start linking variability to physical precesses in the disk, but we need more data of a larger sample in order to understand the big picture 🤓

In general, we find that even if these objects are very close to each other in the HRD, they have VERY different variability properties. Meaning that it is complicated ! There are probably several physical processes happening at the same time.
