We are now revealing the 3D structure of the atmosphere exoplanets. Thanks to @eso.org telescopes and the #ESPRESSO instrument, lead by a great work from Dr. Julia Seidel, we found strong jet streams (faster than any in our Solar System!) in the atmosphere of WAPS-121b. Published in @nature.com!

Happy International Day of Women and Girls in Science from the Remote Worlds Lab! Let's keep promoting science for all children and let's avoid absurd gender biases when buying gifts or clothes to our little creatures. The world is way better, fair and happy if we all contribute to everything.

Five years after he sadly passed away, Kobe Bryant now has two planets named after him. The exoplanets we discovered (nicknamed KOBE-1b and KOBE-1c) are two Neptune-like planets surrounding a late K-dwarf star. Two Mamba's in the sky. @paugasol.bsky.social and the LA Lakers will surely like this.

Since the planets do not transit a priori, we are unsure about their composition. They could still be telluric-dominated planets (super-Earths) or gas-dominated planets (mini-Neptunes). Although some hints of a transit signal of KOBE-1c point to the rocky scenario as the most plausible.

These two planets are inner to the habitable zone of this star, leaving room for additional components that might be revealed in future observations.

Now, one of our targets was KOBE-1 (aka HIP 5957). We obtained more than 80 radial velocity measurements in 3 years and found two very clear signals in the data. One at 8.5 days (KOBE-1b) and another at 29.7 days (KOBE-1c). Their masses are compatible with planets of around 9 and 12 Earth masses.

Today we are very happy to present you KOBE-1, the first planetary system detected by our KOBE experiment. Two small (potentially Neptune-like) planets around a late K-dwarf. Let me give you some insights into this interesting project and new planetary system.

How cool is the poster announcing the conference commemorating the 30th anniversary of the detection of the first exoplanet around a solar-like star? Looking forward to attend!

Adrien Masson, postdoc at our Remote Worlds Lab at @C_Astrobiologia, talking about exoplanet atmospheric escape at the Madrid Area Exoplanet Meeting organized by @esa_es!

On the way (by train!) to beautiful Marseille for a meeting about our #KOBE search for habitable worlds around late K-type stars. First results coming soon…

Hello Astro community! I am an astrophysicist working at the Center for Astrobiology in Madrid (Spain). I search for new planets, focusing on those with potential for supporting life. I also do outreach and love to talk about ethics and philosophy of the universe!
