The HARPS search for southern extra-solar planets. XXXIX. HD175607 b, the most metal-poor G dwarf with an orbiting sub-Neptune
A. Mortier, J. P. Faria, N. C. Santos +16
Context. The presence of a small-mass planet (M0.1\,M) seems, to date, not to depend on metallicity, however, theoretical simulations have shown that stars with subsol…
Ghost in the time series: no planet for Alpha Cen B
Vinesh Rajpaul, Suzanne Aigrain, Stephen J. Roberts
We re-analyse the publicly available radial velocity (RV) measurements for Alpha Cen B, a star hosting an Earth-mass planet candidate, Alpha Cen Bb, with 3.24 day orbital period. W…
A Gaussian process framework for modelling stellar activity signals in radial velocity data
Vinesh Rajpaul, Suzanne Aigrain, Michael A. Osborne +2
To date, the radial velocity (RV) method has been one of the most productive techniques for detecting and confirming extrasolar planetary candidates. Unfortunately, stellar activit…
