The CARMENES Search For Exoplanets Around M Dwarfs, Wolf 1069 b: Earth-mass Planet In The Habitable Zone Of A Nearby, Very Low-mass Star
We present the discovery of an Earth-mass planet (Mbsini=1.36±0.21M⊕) on a 15.6d orbit of a relatively nearby (d∼9.6pc) and low-mass (0.167±0.011M⊙) M5.0V star, Wolf 1069.

ESPRESSO and CARMENES Discover Two Potentially Habitable Exo-Earths Around A Star Near The Sun
“Nature seems bent on showing us that Earth-like planets are very common. With these two we now know 7 in planetary systems quite near to the Sun” explains Alejandro Suárez […]

Two Temperate Earth-mass Planets Orbiting The Nearby Star GJ1002
We report the discovery and characterisation of two Earth-mass planets orbiting in the habitable zone of the nearby M-dwarf GJ~1002 based on the analysis of the radial-velocity (RV) time series […]

Spectropolarimetry as a Means to Address Cloud Composition and Habitability for a Cloudy Exoplanetary Atmosphere in the Habitable Zone
In our solar system, the densely cloud-covered atmosphere of Venus stands out as an example of how polarimetry can be used to gain information on cloud composition and particle mean […]

HD 191939 Revisited: New And Refined Planet Mass Determinations, And A New Planet In The Habitable Zone
HD 191939 (TOI-1339) is a nearby (d=54pc), bright (V=9mag), and inactive Sun-like star (G9 V) known to host a multi-planet transiting system. Ground-based spectroscopic observations confirmed the planetary nature of […]
