HADES RV Programme with HARPS-N at TNG VI. GJ 3942 b behind dominant activity signals
M. Perger, I. Ribas, M. Damasso +29
Short- to mid-term magnetic phenomena on the stellar surface of M-type stars cannot only resemble the effects of planets in radial velocity data, but also may hide them. We analyze…
X-shooter spectroscopy of young stellar objects in Lupus: Lithium, iron, and barium elemental abundances
K. Biazzo, A. Frasca, J. M. Alcalá +9
With the purpose of performing a homogeneous determination of elemental abundances for members of the Lupus T association, we analyzed three chemical elements: lithium, iron, and b…
The GAPS Programme with HARPS-N at TNG XV. A substellar companion around a K giant star identified with quasi-simultaneous HARPS-N and GIANO measurements
E. González - Álvarez, L. Affer, G. Micela +34
Context. Identification of planetary companions of giant stars is made difficult because of the astrophysical noise, that may produce radial velocity (RV) variations similar to tho…
The GAPS programme with HARPS-N at TNG. I: Observations of the Rossiter-McLaughlin effect and characterisation of the transiting system Qatar-1
E. Covino, M. Esposito, M. Barbieri +67
A long-term multi-purpose observational programme has started with HARPS-N@TNG aimed to characterise the global architectural properties of exoplanetary systems. In this first pape…
Long-term stability of spotted regions and the activity-induced Rossiter-McLaughlin effect on V889 Herculis. A synergy of photometry, radial velocity measurements, and Doppler imaging
K. F. Huber, U. Wolter, S. Czesla +4
The young active G-dwarf star V889 Herculis (HD 171488) shows pronounced spots in Doppler images as well as large variations in photometry and radial velocity (RV) measurements. Ho…
