OGLE-2016-BLG-1093Lb: A Sub-Jupiter-mass Spitzer Planet Located in the Galactic Bulge

OGLE-2016-BLG-1093 is a planetary microlensing event that is part of the statistical Spitzer microlens parallax sample. The precise measurement of the microlens parallax effect for this event, combined with the measurement of finite-source effects, leads to a direct measurement of the lens masses and system distance, M <SUB>host</SUB> =0.38-0.57 M <SUB>⊙</SUB> and m <SUB> p </SUB> = 0.59-0.87 M <SUB>Jup</SUB>, and the system is located at the Galactic bulge (D <SUB> L </SUB> ~ 8.1 kpc). Because this was a high-magnification event, we are also able to empirically show that the cheap-space parallax" concept produces well-constrained (and consistent) results for ∣π <SUB>E</SUB>∣. This demonstrates that this concept can be extended to many two-body lenses. Finally, we briefly explore systematics in the Spitzer light curve in this event and show that their potential impact is strongly mitigated by the color constraint."
