An ESPRESSO view of HD 189733 system. Broadband transmission spectrum, differential rotation, and system architecture
E. Cristo, E. Esparza Borges, N. C. Santos +25
The development of state-of-the-art spectrographs has ushered in a new era in the detection and characterization of exoplanetary systems. Our objective is to utilize the high-resol…
The Extreme Stellar-Signals Project III. Combining Solar Data from HARPS, HARPS-N, EXPRES, and NEID
Lily L. Zhao, Xavier Dumusque, Eric B. Ford +37
We present an analysis of Sun-as-a-star observations from four different high-resolution, stabilized spectrographs -- HARPS, HARPS-N, EXPRES, and NEID. With simultaneous observatio…
A compact multi-planet system transiting HIP 29442 (TOI-469) discovered by TESS and ESPRESSO. Radial velocities lead to the detection of transits with low signal-to-noise ratio
M. Damasso, J. Rodrigues, A. Castro-González +52
We followed-up with ESPRESSO the K0V star HIP 29442 (TOI-469), already known to host a validated sub-Neptune companion TOI-469.01. We aim to verify the planetary nature of TOI-469.…
TOI-332 b: a super dense Neptune found deep within the Neptunian desert
Ares Osborn, David J. Armstrong, Jorge Fernández Fernández +49
To date, thousands of planets have been discovered, but there are regions of the orbital parameter space that are still bare. An example is the short period and intermediate mass/r…
Homogeneous search for helium in the atmosphere of 11 gas giant exoplanets with SPIRou
R. Allart, P. -B. Lemée-Joliecoeur, A. Y. Jaziri +31
The metastable helium triplet in the near-infrared (10833Å) is among the most important probes of exoplanet atmospheres. It can trace their extended outer layers and constrain mass…
An unusually low-density super-Earth transiting the bright early-type M-dwarf GJ 1018 (TOI-244)
A. Castro-González, O. D. S. Demangeon, J. Lillo-Box +34
Small planets located at the lower mode of the bimodal radius distribution are generally assumed to be composed of iron and silicates in a proportion similar to that of the Earth.…
