Finding Exoplanets Orbiting Young Active Stars. I. Technique
V. E. Moulds, C. A. Watson, X. Bonfils +2
Stellar activity, such as starspots, can induce radial velocity (RV) variations that can mask or even mimic the RV signature of orbiting exoplanets. For this reason RV exoplanet su…

Stellar jitter from variable gravitational redshift: implications for RV confirmation of habitable exoplanets
H. M. Cegla, C. A. Watson, T. R. Marsh +6
A variation of gravitational redshift, arising from stellar radius fluctuations, will introduce astrophysical noise into radial velocity measurements by shifting the centroid of th…

Disentangling stellar activity and planetary signals
I. Boisse, F. Bouchy, G. Hebrard +3
Photospheric stellar activity might be an important source of noise and confusion in the radial-velocity measurements. RV planet search surveys as well as follow-up of photometric…
