Modeling Asteroseismic Yields for the Roman Galactic Bulge Time-domain Survey
The Astrophysical JournalThe Galactic Bulge Time-Domain Survey (GBTDS) of the Roman Space Telescope will take high-cadence data of the Galactic bulge. We investigate the asteroseismic potential of this survey for red giants.

The Ages of Galactic Bulge Stars with Realistic Uncertainties
The Astrophysical Journal, 2023 Using modern isochrones with customized physics and carefully considered statistical techniques, we recompute the age distribution for a sample of 91 microlensed dwarfs in the Galactic bulge presented by Bensby et al.

The Microlensing Event Rate and Optical Depth from MOA-II 9 Yr Survey Toward the Galactic Bulge
The Astrophysical JournalWe present measurements of the microlensing optical depth and event rate toward the Galactic bulge using the data set from the 2006 to 2014 MOA-II survey, which covers 22 bulge fields spanning ∼42 deg ^2 between −5°

Microlensing maps for the galactic bulge [PDF]
The Astrophysical Journal, 1994 Microlensing maps -- that is, contours of equal numbers of events per $10^6$ source stars -- are provided for the inner Galaxy under two alternative hypotheses : (1) the bulge is an oblate axisymmetric spheroid or (2) the bulge is a prolate bar. Oblate spheroids yield a total of $\sim 12$ events per year per $10^6$ stars at Baade's Window ($\sim 15 ...

OGLE-2014-BLG-1760: A Jupiter–Sun Analogue Residing in the Galactic Bulge
The Astronomical JournalWe present the analysis of OGLE-2014-BLG-1760, a planetary system in the galactic bulge. We combine Keck Adaptive Optics follow-up observations in K -band with re-reduced light-curve data to confirm the source and lens star identifications and stellar ...

Classification of OGLE Variables in Galactic Bulge [PDF]
Journal of Astronomy and Space Sciences, 1997 The miscellaneous variables observed by OGLE Project of searching for dark matter in our Galaxy have been analyzed to find their characteristics. We investigated evolutionary status, shape of light curve, relationship between orbital period and amplitude
