Recovering planet radial velocity signals in the presence of starspot activity in fully convective stars
J. R. Barnes, S. V. Jeffers, G. Anglada-Escude +6
Accounting for stellar activity is a crucial component of the search for ever-smaller planets orbiting stars of all spectral types. We use Doppler imaging methods to demonstrate th…
Radial-Velocity Fitting Challenge. II. First results of the analysis of the data set
X. Dumusque, F. Borsa, M. Damasso +21
Radial-velocity (RV) signals induce RV variations an order of magnitude larger than the signal created by the orbit of Earth-twins, thus preventing their detection. The goal of thi…
No evidence for activity correlations in the radial velocities of Kapteyn's star
Guillem Anglada-Escudé, Mikko Tuomi, Pamela Arriagada +19
Stellar activity may induce Doppler variability at the level of a few m/s which can then be confused by the Doppler signal of an exoplanet orbiting the star. To first order, linear…
Precision radial velocities of 15 M5 - M9 dwarfs
J. R. Barnes, J. S. Jenkins, H. R. A. Jones +8
We present radial velocity measurements of a sample of M5V-M9V stars from our Red-Optical Planet Survey, ROPS, operating at 0.65-1.025 micron. Radial velocities for 15 stars, with…
Two Super-Earths Orbiting the Solar Analogue HD41248 on the edge of a 7:5 Mean Motion Resonance
James S. Jenkins, Mikko Tuomi, Ramon Brasser +2
The number of multi-planet systems known to be orbiting their host stars with orbital periods that place them in mean motion resonances is growing. For the most part, these systems…
