The BANANA project. V. Misaligned and precessing stellar rotation axes in CV Velorum
Simon Albrecht, Joshua N. Winn, Guillermo Torres +8
As part of the BANANA project (Binaries Are Not Always Neatly Aligned), we have found that the eclipsing binary CV Velorum has misaligned rotation axes. Based on our analysis of th…
The ESPRI project: astrometric exoplanet search with PRIMA I. Instrument description and performance of first light observations
J. Sahlmann, T. Henning, D. Queloz +42
The ESPRI project relies on the astrometric capabilities offered by the PRIMA facility of the Very Large Telescope Interferometer for the discovery and study of planetary systems.…
BANANA IV: Two aligned stellar rotation axes in the young eccentric binary system EP Crucis: primordial orientation and tidal alignment
Simon Albrecht, Johny Setiawan, Guillermo Torres +2
With observations of the EP Cru system, we continue our series of measurements of spin-orbit angles in eclipsing binary star systems, the BANANA project (Binaries Are Not Always Ne…
Planetary companions around the metal-poor star HIP 11952
J. Setiawan, V. Roccatagliata, D. Fedele +6
Aims. We carried out a radial-velocity survey to search for planets around metal-poor stars. In this paper we report the discovery of two planets around HIP 11952, a metal-poor sta…
U Sco 2010 outburst: a new understanding of the binary accretion disk and the secondary star
Elena Mason, Alessandro Ederoclite, Robert E. Williams +2
We present optical and NIR spectroscopic observations of U Sco 2010 outburst. From the analysis of lines profiles we identify a broad and a narrow component and show that the latte…
Optical spectroscopy of EX Lupi during quiescence and outburst: Infall, wind, and dynamics in the accretion flow
Aurora Sicilia-Aguilar, Ágnes Kóspál, Johny Setiawan +6
We explore the accretion mechanisms in EX Lupi, prototype of EXor variables, during its quiescence and outburst phases. We analyse high-resolution optical spectra taken before, dur…
