ANDES, the high-resolution spectrograph of the ELT: simulated performance of the CORO module and overview of the high-contrast capabilities for exoplanet observations
M. N'Diaye, A. Simonnin, A. Spang +19
We present the simulated performance of the coronagraph (CORO) module for ANDES, the Extremely Large Telescope (ELT) high-resolution spectrograph. ANDES aims to address a broad ran…
A systematic bias in template-based RV extraction algorithms
André M. Silva, N. C. Santos, J. P. Faria +30
In this paper we identify and explore a previously unidentified, multi meter-per-second, systematic correlation between time and RVs inferred through TM and LBL methods. We evaluat…
Two neighbours of the ultra-short-period Earth-sized planet K2-157 b in the warm Neptunian savanna
A. Castro-González, F. Bouchy, A. C. M. Correia +30
The formation and evolution of ultra-short-period (USP) planets is poorly understood. However, it is widely thought that these planets migrated inwards through interactions with ou…
Revisiting the multi-planetary system of the nearby star HD 20794: Confirmation of a low-mass planet in the habitable zone of a nearby G-dwarf
N. Nari, X. Dumusque, N. C. Hara +44
Close-by Earth analogs and super-Earths are of primary importance because they will be preferential targets for the next generation of direct imaging instruments. Bright and close-…
Galaxy Formation and Symbiotic Evolution with the Inter-Galactic Medium in the Age of ELT-ANDES
Valentina D'Odorico, James S. Bolton, Lise Christensen +21
High-resolution absorption spectroscopy toward bright background sources has had a paramount role in understanding early galaxy formation, the evolution of the intergalactic medium…
