Deciphering the 3D structure of the old Galactic bulge from the OGLE RR Lyrae stars
P. Pietrukowicz, S. Kozlowski, J. Skowron +10
We have analyzed a sample of 27,258 fundamental-mode RR Lyrae variable stars (type RRab) detected recently toward the Galactic bulge by the Optical Gravitational Lensing Experiment…
Pathway to the Galactic Distribution of Planets: Combined Spitzer and Ground-Based Microlens Parallax Measurements of 21 Single-Lens Events
S. Calchi Novati, A. Gould, A. Udalski +82
We present microlens parallax measurements for 21 (apparently) isolated lenses observed toward the Galactic bulge that were imaged simultaneously from Earth and Spitzer, which was…
OGLE-ing the Magellanic System: Stellar populations in the Magellanic Bridge
D. M. Skowron, A. M. Jacyszyn, A. Udalski +11
We report the discovery of a young stellar bridge, that forms a continuous connection between the Magellanic Clouds. This finding is based on number density maps for stellar popula…
OGLE-BLG-RRLYR-12245: An RR Lyrae Star that Switched from a Double- to Single-mode Pulsation
I. Soszynski, W. A. Dziembowski, A. Udalski +10
We report the discovery of an RR Lyrae star that experienced a switching of its pulsation mode. OGLE-BLG-RRLYR-12245 was discovered as a double-mode RRd star from the observations…
