Magnetic cycles and radial-velocity for 8 stars
The ever increasing level of precision achieved by present and future radial velocity instruments is opening the way to the discovery of very low mass, long period planets (e.g.... -
HD 147018, 171238 and 204313 radial velocities
We report the detection of a double planetary system around HD140718 as well as the discovery of two long period and massive planets orbiting HD171238 and HD204313. Those... -
Abundances in solar analogs
We derive the abundance of 19 elements in a sample of 64 stars with fundamental parameters very similar to solar, which minimizes the impact of systematic errors in our... -
Stellar parameters of metal-rich solar-type stars
To date, metallicity is the only parameter of a star that appears to clearly correlate with the presence of planets and their properties. To check for new correlations between... -
ELODIE survey for northern extrasolar planets III
We present here the radial-velocity measurements for 9 solar-type stars: Ups And (HD 9826), HD 74156, 55 Cnc (HD 75732), 47 UMa (HD 95128), 70 Vir (HD 117176), 14 Her (HD... -
Magnetic activity of 6 young solar stars. II
The present paper is the second of a series dedicated to the study of the magnetic activity in a selected sample of young solar analogues. The sample includes five single G0-G5V... -
Starspot cycles of six young solar analogues
A long-term photometric monitoring of a selected sample of solar analogues has been carried out since early nineties as part of "The Sun in tim" project, which is aimed at a... -
Fast-rotating nearby solar-type stars. I.
We present the results of high-resolution spectroscopic and high-precision photometric observations on a sample of 129 late-F and G-type nearby stars selected on the basis of...
