Empirical Contrast Model for High-Contrast Imaging -- A VLT/SPHERE Case Study
Benjamin Courtney-Barre, Robert De Rosa, Rosita Kokotanekova +4
The ability to accurately predict the contrast achieved from high contrast imagers is important for efficient scheduling and quality control measures in modern observatories. We ai…
Two long-period transiting exoplanets on eccentric orbits: NGTS-20 b (TOI-5152 b) and TOI-5153 b
S. Ulmer-Moll, M. Lendl, S. Gill +50
Long-period transiting planets provide the opportunity to better understand the formation and evolution of planetary systems. Their atmospheric properties remain largely unaltered…
SPHERE adaptive optics performance for faint targets
M. I. Jones, J. Milli, I. Blanchard +3
Context: High contrast imaging is a powerful technique to detect and characterize planetary companions at large orbital separations from their parent stars. Aims: We aim at studyin…
Precise radial velocities of giant stars XVI. Planet occurrence rates from the combined analysis of the Lick, EXPRESS, and PPPS giant star surveys
Vera Wolthoff, Sabine Reffert, Andreas Quirrenbach +3
RV surveys of evolved stars allow us to probe a higher stellar mass range compared to main-sequence samples. Differences between the planet populations can be caused by either the…
HD 76920b pinned down: a detailed analysis of the most eccentric planetary system around an evolved star
C. Bergmann, M. I. Jones, J. Zhao +9
We present 63 new multi-site radial velocity measurements of the K1III giant HD 76920, which was recently reported to host the most eccentric planet known to orbit an evolved star.…
Four Jovian planets around low-luminosity giant stars observed by the EXPRESS and PPPS
M. I. Jones, R. Wittenmyer, C. Aguilera-Gómez +12
We report the discovery of planetary companions orbiting four low-luminosity giant stars with M between 1.04 and 1.39 M. All four host stars have been independently…
