Abstract:
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,
Mhost=0.38-0.57M☉ and mp=0.59-0.87MJup, and the system is
located at the Galactic bulge (DL∼8.1kpc). 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 |πE|. 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.
Description:
This event was first announced by the Early Warning System (EWS) of
the Optical Gravitational Lensing Experiment survey (OGLE-IV) on 2016
June 11. Thus, this event is designated OGLE-2016-BLG-1093. The event
was observed using the 1.3m Warsaw telescope (1.4deg2 science
camera) located at Las Campanas Observatory in Chile. The Microlensing
Observations in Astrophysics (MOA) detected this event on 2016 June
24, using the 1.8m telescope located at the University of Canterbury
Mount John Observatory in New Zealand. The Korea Microlensing
Telescope Network (KMTNet) also detected this event using a telescope
network consisting of three identical 1.6m telescopes (4deg2 science
cameras) located at the Cerro Tololo Inter-American Observatory in
Chile (KMTC), the South African Astronomical Observatory in South
Africa (KMTS), and the Siding Spring Observatory in Australia (KMTA).
In addition, this event was chosen as a target of the Spitzer
Microlensing Campaign and observed using the Spitzer Space Telescope
with the 3.6µm channel of the infrared Array Camera (IRAC).
