The 3D structure shows a lower layer distributing energy towards both sides from the substellar point (the point of the planet facing the star), the middle layer shows incredibly accelerating jets (13 km/s to 26 km/s!) and the upper layer is blowing away hydrogen due to the heating of the atmosphere

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!

Great congrats Bibiana! Outstanding results you two publish today!

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.

Amazing art work from children to commemorate the International Day of Women and Girls in Science. Check out the winners of the Spanish Astronomical Society contest. I am fully amazed of the quality of the drawings. Brith future ahead!

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.

KOBE 1: The first planetary system from the KOBE survey. Two planets likely residing in the sub-Neptune mass regime around a late K-dwarf. O. Balsalobre-Ruza et. al. https://arxiv.org/abs/2502.01249

This paper is the result of a great effort from the KOBE team, composed by researchers from Porto, Marseille, Geneva and Madrid. The paper, lead by Olga Balsalobre-Ruza (from the Center for Astrobiology in Madrid) is available in A&A. www.aanda.org/articles/aa/...

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.

Why focusing on late K-dwarfs? Because 1) we can detect planets in their habitable zone easier than in the hotter G-dwarfs and 2) because their habitable-zone planets are not threatened as much as those around M-dwarfs. late K-dwarfs are the Goldlilock environments for habitability!

KOBE is a radial velocity survey using the CARMENES instrument (Calar Alto, Spain), focused on the search for habitable worlds around late K-dwarfs. 50 stars in this regime are being followed since January 2021 with the objective of finding planets in their habitable zones.

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!

Totalmente de acuerdo con mi amigo Carlos Briones (@brionesci.bsky.social). El espacio, y Marte en particular, debe ser contemplado con admiración y mucho respeto. Su explotación, además, nos pone a todos en peligro.

Glad to see many new people in this plataform movimg away from crazyness. So: I am an astrophysicist looking for new exoplanets and studying those new pale dots. I work at the Center for Astrobiology in Madrid. I use this account to learn and disseminate the work of my team, the Remote Worlds Lab.

Let’s go for it!

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…

The PhD supervisors would be myself (Jorge Lillo-Box,
@jlillobox), David Barrado (@David_Barrado) and Nuria Huélamo.

More information about the group at:
remote-worlds-lab.cab.inta-csic.es/index.html

The PhD project is related to "the KOBE experiment" (kobe.caha.es) that we are leading from the Remote Worlds group at CAB.

The deadline for submitting applications is *November 7*. You can find the call at this link:
www.inta.es/INTA/es/bols...

We are offering a 4-year PhD contract at the
@C_Astrobiologia to study exoplanetary systems in K-type stars with the @ESA_Plato and @ESA_JWST missions as well as terrestrial instrumentation. Anyone interested, please contact us as soon as possible. +info👇

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!
