WALTzER: Wide-band Atmospheric Laboratory for Transiting Exoplanet Research

A. G. Sreejith, L. Fossati, M. Lendl +81

Understanding the origin and evolution of planetary atmospheres, and the connection between their lower and upper atmospheric layers, remains a fundamental challenge in exoplanet s…

Transit timing and starspot-induced transit depth variations in the 17 Myr old HIP 67522 system

H. Chakraborty, M. Lendl, A. Nigioni +27

HIP 67522 is a one of the youngest multi-planetary systems discovered to date. The 17 Myr-old, Sun-like star is part of the Scorpius-Centarus OB association and is known to host tw…

Precise measurement of WASP-31 b's Rossiter-McLaughlin effect and characterization of the planet transmission spectra

M. Steiner, V. Bourrier, D. Ehrenreich +23

Context. Hot Jupiters are ideal natural laboratories to investigate atmospheric composition and dynamics. However, high-resolution transmission spectroscopy is currently limited by…

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…

The ESPRESSO transmission spectrum of HD189733b : Extracting the planetary sodium and lithium signatures amid stellar contamination

D. Mounzer, W. Dethier, C. Lovis +20

While transmission spectroscopy has allowed us to detect many atomic and molecular species in exoplanet atmospheres, the improvement in resolution and signal-to-noise ratio enabled…

CORALIE radial-velocity search for companions around evolved stars (CASCADES) IV: New planetary systems around HD 87816, HD 94890, and HD 102888 and an update on HD 121056

E. Fontanet, S. Udry, D. Ségransan +25

With around 200 detections of exoplanets around giant stars to date, our knowledge of the population of exoplanets orbiting evolved hosts more massive than the Sun remains limited.…

Three Hot Jupiters transiting K-dwarfs with a significant heavy element mass

Y. G. C. Frensch, F. Bouchy, G. Lo Curto +50

Albeit at a lower frequency than around hotter stars, short-period gas giants around low-mass stars ( K) do exist, despite predictions from planetary populat…

ESPRESSO reveals blueshifted neutral iron emission lines on the dayside of WASP-76 b

A. R. Costa Silva, O. D. S. Demangeon, N. C. Santos +34

Ultra hot Jupiters (gas giants, Teq>2000 K) are intriguing exoplanets due to their extreme atmospheres. Their torrid daysides can be characterised using ground-based high-resolutio…

SAGE: A tool to constrain impacts of stellar activity on transmission spectroscopy

Hritam Chakraborty, Monika Lendl, Babatunde Akinsanmi +2

Transmission spectroscopy is a proven technique to study a transiting exoplanet's atmosphere. However, stellar surface inhomogeneities, spots and faculae, alter the observed transm…
