A. Suárez MascareñoSay hello to two new nearby potentially habitable #exoplanets ! #GJ1002, a tiny red-dwarf, hosts two Earth-mass planets. The article, a collaboration between the #ESPRESSO and #CARMENES consortia, led by me, is available now on #arxiv https://arxiv.org/pdf/2212.07332.pdf #astronomy
The planets were detected using high precision radial velocities from #ESPRESSO and #CARMENES, which were analysed using multi-dimensional Gaussian processes to model the stellar activity and disentangle it from the planetary signal.
The #ESPRESSO data in particular looks astonishingly clean. You don't even need to phase fold it! It was not so long ago that we could only see this kind of easy-to-spot variations in the case of giant planets.
The phase folded curves look fantastic, and once again highlight the excellent performance of #ESPRESSO and the #ESO #VLT telescopes. Very likely the most powerful radial velocity facility in the world.
Both planets orbit within the #HabitableZone of the star. As #GJ1002 is a tiny red-dwarf, the habitable zone is very close to the star. With an orbital period of 10 days, GJ 1002 b receives a similar flux as the Earth.
The article involves the work of many people, from the
#ESPRESSO and #CARMENES consortia. Any of the two would have had much weaker results alone. This work, same as many others, highlights the importance of collaboration in science. Together we go further than alone

ESPRESSO and CARMENES discover two potentially habitable exo-Earths around a star near the Sun
An international scientific team led by researchers at the Instituto de Astrofísica de Canarias (IAC) has discovered the presence of two planets with Earth-like masses in orbit around the star GJ 1002, a red dwarf not far from the Solar System. Both planets are in the habitability zone of the star
So happy to see @nasa liking my work! https://exoplanets.nasa.gov/news/1719/discovery-alert-two-nearby-worlds-might-be-habitable/ #exoplanets #gj1002 #astrophysics
