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

Great congrats Bibiana! Outstanding results you two publish today!

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.

Let’s go for it!

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