An extremely low-density and temperate giant exoplanet
A. Santerne, L. Malavolta, M. R. Kosiarek +68
Transiting extrasolar planets are key objects in the study of the formation, migration, and evolution of planetary systems. In particular, the exploration of the atmospheres of gia…
Using HARPS-N to characterise the long-period planets in the PH-2 and Kepler-103 systems
Sophie C. Dubber, Annelies Mortier, Ken Rice +26
We present confirmation of the planetary nature of PH-2b, as well as the first mass estimates for the two planets in the Kepler-103 system. PH-2b and Kepler-103c are both long-peri…
Testing the Spectroscopic Extraction of Suppression of Convective Blueshift
M. Miklos, T. W. Milbourne, R. D. Haywood +21
Efforts to detect low-mass exoplanets using stellar radial velocities (RVs) are currently limited by magnetic photospheric activity. Suppression of convective blueshift is the domi…
An 11 Earth-Mass, Long-Period Sub-Neptune Orbiting a Sun-like Star
Andrew W. Mayo, Vinesh M. Rajpaul, Lars A. Buchhave +27
Although several thousands of exoplanets have now been detected and characterized, observational biases have led to a paucity of long-period, low-mass exoplanets with measured mass…
The GAPS Programme with HARPS-N at TNG XIX. Atmospheric Rossiter-McLaughlin effect and improved parameters of KELT-9b
F. Borsa, M. Rainer, A. S. Bonomo +40
In the framework of the GAPS project, we observed the planet-hosting star KELT-9 (A-type star, VsinI110 km/s) with the HARPS-N spectrograph at the TNG. In this work we analys…
Temporal evolution and correlations of optical activity indicators measured in Sun-as-a-star observations
J. Maldonado, D. F. Phillips, X. Dumusque +29
(Abridged) We perform a detailed study of the main optical activity indicators (Ca II H & K, Balmer lines, Na I D D, and He I D) measured for the Sun…
