The ExoGRAVITY survey: A K-band spectral library of giant exoplanet and brown dwarf companions
J. Kammerer, T. O. Winterhalder, S. Lacour +106
Direct observations of exoplanet and brown dwarf companions with near-infrared interferometry, first enabled by the dual-field mode of VLTI/GRAVITY, provide unique measurements of…
Architecture of planetary systems with and without outer giant planets I. Inner planet detections around HD 23079, HD 196067, and HD 86226
J. -B. Delisle, J. P. Faria, D. Ségransan +22
Understanding the link between outer giant planets (OGPs) and inner light planets (ILPs) is key to understanding planetary system formation and architecture. The correlation betwee…
Spectral analysis of two directly imaged benchmark L dwarf companions at the stellar-substellar boundary
William Ceva, Elisabeth C. Matthews, Emily L. Rickman +7
We used multiple epochs of high-contrast imaging spectrophotometric observations to determine the atmospheric characteristics and thermal evolution of two previously detected bench…
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…
