The time variability and spectra of directly imaged companions provide insight into their physical properties and atmospheric dynamics.
We analyze data from the final two years of the Cassini mission to retrieve the distributions of methane, ethane, acetylene, ethylene, and benzene in Saturn’s upper stratosphere and mesosphere from […]
ESPRESSO (Echelle SPectrograph for Rocky Exoplanets and Stable Spectroscopic Observations) is a VLT ultra-stable high resolution spectrograph installed at ESO’s Paranal Observatory in Chile at the end of 2017 and […]
For the first time, an instrument to find planets light years away was used on an object in the Solar System, in a study on Jupiter’s winds.
The latest generation of high-resolution spectrograph instruments on 10m-class telescopes continue to pursue challenging science cases. Consequently, ever more precise calibration methods are necessary to enable trail-blazing science methodology.
As we enter the era of TESS and JWST, instrumentation that can carry out radial velocity measurements of exoplanet systems is in high demand.
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.
“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 […]
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 […]
Aims. The project aims to understand better the role of wide brown dwarf companions on planetary systems.
