Description
In this seminar, I will present the latest results of the Millennium Nucleus of Young Exoplanets and their Moons (YEMS) team. We presented the first detection of an exosatellite around a BD companion. This discovery has been made with the use of the radial velocity technique, the same technique that was used to detect the first exoplanet around a solar-type star. In this case, the BD companion was the target of the radial velocity monitoring. We found a signal compatible with a sub-Jupiter mass satellite around the BD companion.
I will also present the confirmation of the youngest exoplanet ever detected, around the star Elias 2-24. The planet is still forming, and it is detected within the protoplanetary disk. The confirmation of Elias 2-24 b, currently the youngest planet detected through high-contrast imaging, has important implications for planet formation timescales, demonstrating that giant planets can form through core accretion at separations of ~50 au within only ∼ 1 Myr, supporting the idea that such planets are responsible for the gaps observed in large and bright disks at these young ages.
