Red noise versus planetary interpretations in the microlensing event OGLE-2013-BLG-446
For all exoplanet candidates, the reliability of a claimed detection needs to be assessed through a careful study of systematic errors in...
The VLT-FLAMES Tarantula Survey. XXIII. Two massive double-lined binaries in 30 Doradus
We investigate the characteristics of two newly discovered short-period, double-lined, massive binary systems, VFTS 450 (O9.7II--Ib+O7::)...
MLS110213:022733+130617: a new eclipsing polar above the period gap
This study confirms MLS110213:022733+130617 as a new eclipsing polar. We performed optical spectroscopic, polarimetric and photometric...
Identification of strong photometric activity in the components of LHS 1070
Activity in low-mass stars is an important ingredient in the evolution of such objects. Fundamental physical properties such as age,...
A photometric and spectroscopic study of NSVS 14256825: the second sdOB+ dM eclipsing binary
We present an analysis of UBVRCICJH photometry and phase-resolved optical spectroscopy of NSVS 14256825, an HW Vir type binary. The...
Two possible circumbinary planets in the eclipsing post-common envelope system NSVS 14256825
We present an analysis of eclipse timings of the post-common envelope binary NSVS 14256825, which is composed of an sdOB star and a dM...
OGLE-2011-BLG-0265Lb: A Jovian Microlensing Planet Orbiting an M Dwarf
We report the discovery of a Jupiter-mass planet orbiting an M-dwarf star that gave rise to the microlensing event OGLE-2011-BLG-0265....
