Microlensig Binaries with Candidate Brown Dwarf Companions

I. -G. Shin, C. Han, A. Gould +152

Brown dwarfs are important objects because they may provide a missing link between stars and planets, two populations that have dramatically different formation history. In this pa…

High-precision photometry by telescope defocussing. IV. Confirmation of the huge radius of WASP-17b

John Southworth, M Dominik, X-S Fang +29

We present photometric observations of four transits in the WASP-17 planetary system, obtained using telescope defocussing techniques and with scatters reaching 0.5 mmag per point.…

The Transiting System GJ1214: High-Precision Defocused Transit Observations and a Search for Evidence of Transit Timing Variation

K. B. W. Harpsøe, S. Hardis, T. C. Hinse +37

Aims: We present 11 high-precision photometric transit observations of the transiting super-Earth planet GJ1214b. Combining these data with observations from other authors, we inve…

Age and helium content of the open cluster NGC 6791 from multiple eclipsing binary members. II. age dependencies and new insights

K. Brogaard, D. A. VandenBerg, H. Bruntt +11

Models of stellar structure and evolution can be constrained by measuring accurate parameters of detached eclipsing binaries in open clusters. Multiple binary stars provide the mea…

A New Type of Ambiguity in the Planet and Binary Interpretations of Central Perturbations of High-Magnification Gravitational Microlensing Events

J. -Y. Choi, I. -G. Shin, C. Han +118

High-magnification microlensing events provide an important channel to detect planets. Perturbations near the peak of a high-magnification event can be produced either by a planet…

Characterizing Low-Mass Binaries From Observation of Long Time-scale Caustic-crossing Gravitational Microlensing Events

I. -G. Shin, C. Han, J. -Y. Choi +119

Despite astrophysical importance of binary star systems, detections are limited to those located in small ranges of separations, distances, and masses and thus it is necessary to u…
