Comparing telluric removal methods in their capability to recover injected exoplanet atmosphere signals with high resolution emission spectroscopy
Marcelo Aron Fetzner Keniger, Matteo Brogi, David Armstrong +1
For ground-based high-resolution spectroscopic exoplanet atmosphere studies, removing the contamination from telluric and stellar lines is a crucial step in the analysis process. D…
AGN in Gaia Alerts: from flares to Changing Look Quasars
M. Dennefeld, T. Pursimo, C. Carvalho +11
The Gaia Alerts system is providing alerts on a variety of objects displaying a significant photometric change detected by the Gaia satellite from one passage to the next one over…
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…
Obliquities of Exoplanet Host Stars: 19 New and Updated Measurements, and Trends in the Sample of 205 Measurements
Emil Knudstrup, Simon H. Albrecht, Joshua N. Winn +17
Measurements of the obliquities in exoplanet systems have revealed some remarkable architectures, some of which are very different from the Solar System. Nearly 200 obliquity measu…
