A Planetary Companion around a Metal-Poor Star with Extragalactic Origin
J. Setiawan, R. Klement, T. Henning +4
We report the detection of a planetary companion around HIP 13044, a metal-poor star on the red Horizontal Branch. The detection is based on radial velocity observations with FEROS…
A Giant Planet Around a Metal-poor Star of Extragalactic Origin
Johny Setiawan, Rainer J. Klement, Thomas Henning +6
Stars in their late stage of evolution, such as Horizontal Branch stars, are still largely unexplored for planets. We report the detection of a planetary companion around HIP 13044…
The barycentric motion of exoplanet host stars: tests of solar spin-orbit coupling
M. A. C. Perryman, T. Schulze-Hartung
Empirical evidence suggests a tantalising but unproven link between various indicators of solar activity and the barycentric motion of the Sun. The latter is exemplified by transit…
