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…

H-activity and ages for stars in the SARG survey
E. Sissa, R. Gratton, S. Desidera +7
Stellar activity influences radial velocity (RV) measurements and can also mimic the presence of orbiting planets. As part of the search for planets around the components of wide b…

A vigorous activity cycle mimicking a planetary system in HD200466
E. Carolo, S. Desidera, R. Gratton +9
Stellar activity can be a source of radial velocity (RV) noise and can reproduce periodic RV variations similar to those produced by an exoplanet. We present the vigorous activity…
