SWEET-Cat updated. New homogenous spectroscopic parameters
S. G. Sousa, V. Adibekyan, E. Delgado-Mena +14
Context: Exoplanets have now been proven to be very common. The number of its detections continues to grow following the development of better instruments and missions. One key ste…
Planets around evolved intermediate-mass stars in open clusters II. Are there really planets around IC4651No9122, NGC2423No3 and NGC4349No127?
E. Delgado Mena, C. Lovis, N. C. Santos +10
(shorter version)The aim of this work is to search for planets around intermediate-mass stars in open clusters by using RV data obtained with HARPS from an extensive survey with mo…
Disentangling planetary and stellar activity features in the CoRoT-2 light curve
G. Bruno, M. Deleuil, J. -M. Almenara +7
[Abridged] Context. Stellar activity is an important source of systematic errors and uncertainties in the characterization of exoplanets. Most of the techniques used to correct for…
An extreme planetary system around HD219828. One long-period super Jupiter to a hot-neptune host star
N. C. Santos, A. Santerne, J. P. Faria +19
With about 2000 extrasolar planets confirmed, the results show that planetary systems have a whole range of unexpected properties. We present a full investigation of the HD219828 s…
Evidence for a spectroscopic direct detection of reflected light from 51 Peg b
J. H. C. Martins, N. C. Santos, P. Figueira +11
The detection of reflected light from an exoplanet is a difficult technical challenge at optical wavelengths. Even though this signal is expected to replicate the stellar signal, n…
