Limb-darkening measurements for a cool red giant in microlensing event OGLE 2004-BLG-482

M. Zub, A. Cassan, D. Heyrovsky +47

Aims: We present a detailed analysis of OGLE 2004-BLG-482, a relatively high-magnification single-lens microlensing event which exhibits clear extended-source effects. These events…

Interpretation of Strong Short-Term Central Perturbations in the Light Curves of Moderate-Magnification Microlensing Events

C. Han, K. -H. Hwang, D. Kim +87

To improve the planet detection efficiency, current planetary microlensing experiments are focused on high-magnification events searching for planetary signals near the peak of len…

Mass measurement of a single unseen star and planetary detection efficiency for OGLE 2007-BLG-050

V. Batista, Subo Dong, A. Gould +93

We analyze OGLE-2007-BLG-050, a high magnification microlensing event (A ~ 432) whose peak occurred on 2 May, 2007, with pronounced finite-source and parallax effects. We compute p…

Difference imaging photometry of blended gravitational microlensing events with a numerical kernel

M. D. Albrow, K. Horne, D. M. Bramich +23

The numerical kernel approach to difference imaging has been implemented and applied to gravitational microlensing events observed by the PLANET collaboration. The effect of an err…

Period-Luminosity Relations for Type II Cepheids and their Application

Noriyuki Matsunaga, Michael W. Feast, John W. Menzies

JHKs magnitudes corrected to mean intensity are estimated for LMC type II Cepheids in the OGLE-III survey. Period-luminosity (PL) relations are derived in JHKs as well as in a redd…

Discovery of the first symbiotic star in NGC6822

A. Kniazev, P. Vaisanen, P. A. Whitelock +10

We report the discovery of the first symbiotic star (V=21.6, K_S=15.8 mag) in the Local Group dwarf irregular galaxy NGC6822. This star was identified during a spectral survey of H…

A systematic fitting scheme for caustic-crossing microlensing events

N. Kains, A. Cassan, K. Horne +42

We outline a method for fitting binary-lens caustic-crossing microlensing events based on the alternative model parameterisation proposed and detailed in Cassan (2008). As an illus…
