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…
Bayesian photon counting with electron-multiplying charge coupled devices (EMCCDs)
Kennet B. W. Harpsøe, Michael I. Andersen, Per Kjægaard
The EMCCD is a CCD type that delivers fast readout and negligible detector noise, making it an ideal detector for high frame rate applications. Because of the very low detector noi…
Qatar-2: A K dwarf orbited by a transiting hot Jupiter and a more massive companion in an outer orbit
Marta L. Bryan, Khalid A. Alsubai, David W. Latham +23
We report the discovery and initial characterization of Qatar-2b, a hot Jupiter transiting a V = 13.3 mag K dwarf in a circular orbit with a short period, P_ b = 1.34 days. The mas…
Microlensing Binaries Discovered through High-Magnification Channel
I. -G. Shin, J. -Y. Choi, S. -Y. Park +148
Microlensing can provide a useful tool to probe binary distributions down to low-mass limits of binary companions. In this paper, we analyze the light curves of 8 binary lensing ev…
Discovery and Mass Measurements of a Cold, 10-Earth Mass Planet and Its Host Star
Y. Muraki, C. Han, D. P. Bennett +125
We present the discovery and mass measurement of the cold, low-mass planet MOA-2009-BLG-266Lb, made with the gravitational microlensing method. This planet has a mass of m_p = 10.4…
I. Flux and color variations of the quadruply imaged quasar HE 0435-1223
D. Ricci, J. Poels, A. Elyiv +32
aims: We present VRi photometric observations of the quadruply imaged quasar HE 0435-1223, carried out with the Danish 1.54m telescope at the La Silla Observatory. Our aim was to m…
