Check out the last press release of the #XUE collaboration. Very proud of our PhD student Kenny for all the work she put in to get those nice results!

OH MY GOD!! WE HAVE THE COMBINED WEBB AND CHANDRA VIEW OF NGC 602!! IT’S SO BEAUTIFUL 🤩🌌
This is a composite image of star cluster NGC 602, in vibrant and festive colors. The shape of the star cluster strongly resembles a holiday wreath. The cluster includes a giant dust cloud ring, shown in greens, yellows, blues, and oranges. The green hues and feathery edges of the ring cloud create the appearance of a wreath made of evergreen boughs. Hints of red representing X-rays provide shading, highlighting layers within the wreath-like ring cloud. The image is aglow with specks and dots of colorful, festive light, in blues, golds, whites, oranges, and reds. These lights represent stars within the cluster. Some of the lights gleam with diffraction spikes, while others emit a warm, diffuse glow. Upon closer inspection, many of the glowing specks have spiraling arms, indicating that they are, in fact, distant galaxies. Credit: X-ray: NASA/CXC; Infrared: ESA/Webb, NASA & CSA, P.

Können Planeten auch in Stern­ent­stehungs­regionen entstehen, die vom energiereichen UV-Licht massereicher Sterne durchflutet werden? @mpoessel.de und @astrophysikerin.bsky.social fragen heute Abend bei Astro & Co @maclart.bsky.social vom @mpi-astro.bsky.social

Ankündigung der Online-Talkrunde zum Thema "Planetenentstehung unter härtesten Bedingungen" mit Carolin Liefke, Markus Pössel und María Claudia Ramírez-Tannus am 22. Januar 2024 um 19 Uhr live auf der Facebook-Seite und auf dem Youtube-Kanal des Hauses der Astronomie mit einer künstlerischen Darstellung einer protoplanetaren Scheibe in einem Nebel. In der Ferne ein Stern, der eine leere Blase um sich gebildet hat

Strong UV radiation? Doesn't matter, water and organic molecules still form in protoplanetary discs, as @maclart.bsky.social from MPIA and her team have found out with JWST

Observations of planetary cradles find water and conditions for forming Earth-like planets even in h...
Planets like our Earth, including planets with water, could form even in the harshest known star-forming environments, drenched by hard UV light from massive stars. That is a main result of analyses o...

Starke UV-Strahlung? Egal, Wasser und organische Moleküle bilden sich trotzdem in protoplanetaren Scheiben, wie María Claudia Ramírez-Tannus vom MPIA und ihr Team mit dem JWST herausgefunden haben

Beobachtungen zeigen: Wasser und erdähnliche Planeten auch in unwirtlichen kosmischen Regionen
Planeten wie unsere Erde, auch solche mit Wasser, könnten sogar in den unwirtlichsten bekannten Sternentstehungsumgebungen entstehen, die von energiereichem UV-Licht massereicher Sterne durchflutet w...

A couple of weeks ago the first paper of the XUE collaboration was accepted 🔭. We are studying the properties of disks in extreme UV radiation environments and trying to figure out what massive stars do to the forming sites of Earth-like planets.

🚨Paper alert!! 🔭🚨

This is the first first author paper of A. Derkink from API in Amsterdam. We present a study of the spectroscopic variability of massive pre-main sequence stars in order to learn about the physical processes happening in their disks...

👋 Hola!! I'm new 🙃... I'm a Colombian astronomer 🇨🇴 now a postdoc fellow at MPIA 🔭 in Heidelberg 🇩🇪. I study young massive stars and planet formation in extreme radiation environments 🌌. I'm the PI of the XUE collaboration 🌞 and the mom of a two year old.
