Spitzer Microlensing Parallax Reveals Two Isolated Stars in the Galactic Bulge
Spitzer Microlensing Parallax Reveals Two Isolated Stars in the Galactic Bulge
We report the mass and distance measurements of two single-lens events from the 2017 Spitzer microlensing campaign. The ground-based observations yield the detection of finite-source effects, and the microlens parallaxes are derived from the joint analysis of ground-based observations and Spitzer observations. We find that the lens of OGLE-2017-BLG-1254 is …
