MSc Astronomy student @ IAG/USP 🇧🇷 | Former: UFMG, Uppsala University | Interested in star clusters & stellar formation ✨ Looking for PhD positions for 2026!
I feel like whenever I get the feedback corrections of my supervisor over my dessertation (which I am currently writing), I get a little anxiou with all the small typos and mistakes I let pass. But at least that might be reasurring for her that I am not using any AI to write for me haha

I think Katabasis is a MUST read for every academic that enjoys fantasy, I am enjoying it a lot!

The Pleiades, a.k.a. The Seven Sisters or M45. Pleiades is known for its bright, blue stars and the surrounding reflection nebulae. Recent work has shown that it is a part of a much larger stellar complex that spans over 2,000 light years.

Amazing work!
New paper from my group!
Stars aren’t born alone—they form in massive associations. If we want to understand how stars and planetary systems form, we need to figure out where today’s clusters came from… and where all their long-lost siblings ended up.

Lost Sisters Found: TESS and Gaia Reveal a Dissolving Pleiades Complex
Most star clusters dissolve into the Galaxy over tens to hundreds of millions of years after they form. While recent Gaia studies have honed our view of cluster dispersal, the exact chronology of whic...

Here's a fantastic opportunity for a university student to work on outreach for cutting edge astronomical research: Gaia DR4.
I'd argue that the Gaia Mission should have had a full time person in this role since before 2018, but at least this is something, right?

3 months until my MSc defense. Things are starting to clear up, and I know that I am gonna finish on time. But still very scary, specially the presentation.

I simply found a Korean research group on star formation that works exactly with what I do. I might ask my supervisor to spend some time there during my PhD 👀

Currently characterizing the Ruprecht 79 open cluster using Gaia DR3 data. It is nice to see how its Cepheid agrees a lot with the mean cluster proper motion (as well as in the plx diagram) 🔭🧪

Selection functions are REALLY important - that's the conclusion of our new paper on the open cluster selection function! 🔭☄️ #galactic
Even simple things (like a cluster's orbit) can cause a *major* boost to cluster detectability, biasing results not corrected for selection effects in *big* ways.
