The Neptunian ridge planet WASP-156 b does not have a polar orbit
M. Lafarga, J. I. Espinoza-Retamal, H. M. Cegla +25
The population of short-period exo-Neptunes is thought to be shaped by an interplay between different dynamical mechanisms, such as orbital migration and tidal effects, and photoev…
A Decade of Solar High-Fidelity Spectroscopy and Precise Radial Velocities from HARPS-N
X. Dumusque, K. Al Moulla, M. Cretignier +53
We recently released 10 years of HARPS-N solar telescope and the goal of this manuscript is to present the different optimisations made to the data reduction, to describe data cura…
ATREIDES I. Embarking on a trek across the exo-Neptunian landscape with the TOI-421 system
V. Bourrier, M. Steiner, A. Castro-González +75
The distribution of close-in exoplanets is shaped by the interplay between atmospheric and dynamical processes. The Neptunian Desert, Ridge, and Savanna illustrate the sensitivity…
Towards understanding stellar variability at the sub m/s level: Isolating granulation signals in synthetic spectral lines
Ginger Frame, Heather M. Cegla, Veronika Witzke +5
Granulation in the photospheres of FGK-type stars induces variability in absorption lines, complicating exoplanet detection via radial velocities and characterisation via transmiss…
A possible misaligned orbit for the young planet AU Mic c
H. Yu, Z. Garai, M. Cretignier +98
The AU Microscopii planetary system is only 24 Myr old, and its geometry may provide clues about the early dynamical history of planetary systems. Here, we present the first measur…
