IVOA Recommendation: VOEvent Transport Protocol Version 2.0

Alasdair Allan, Robert B. Denny, John D. Swinbank

The IVOA VOEvent Recommendation defines a means of describing transient celestial events but, purposely, remains silent on the topic of how those descriptions should be transmitted…

Candidate Gravitational Microlensing Events for Future Direct Lens Imaging

C. B. Henderson, H. Park, T. Sumi +76

The mass of the lenses giving rise to Galactic microlensing events can be constrained by measuring the relative lens-source proper motion and lens flux. The flux of the lens can be…

Gravitational Binary-lens Events with Prominent Effects of Lens Orbital Motion

H. Park, A. Udalski, C. Han +58

Gravitational microlensing events produced by lenses composed of binary masses are important because they provide a major channel to determine physical parameters of lenses. In thi…

A possible binary system of a stellar remnant in the high magnification gravitational microlensing event OGLE-2007-BLG-514

N. Miyake, A. Udalski, T. Sumi +78

We report the extremely high magnification (A > 1000) binary microlensing event OGLE-2007-BLG-514. We obtained good coverage around the double peak structure in the light curve via…

OGLE-2008-BLG-510: first automated real-time detection of a weak microlensing anomaly - brown dwarf or stellar binary?

V. Bozza, M. Dominik, N. J. Rattenbury +103

The microlensing event OGLE-2008-BLG-510 is characterised by an evident asymmetric shape of the peak, promptly detected by the ARTEMiS system in real time. The skewness of the ligh…

Characterizing Lenses and Lensed Stars of High-Magnification Single-lens Gravitational Microlensing Events With Lenses Passing Over Source Stars

J. -Y. Choi, I. -G. Shin, S. -Y. Park +148

We present the analysis of the light curves of 9 high-magnification single-lens gravitational microlensing events with lenses passing over source stars, including OGLE-2004-BLG-254…
