Spitzer parallax of OGLE 2015 BLG 0966 a cold Neptune in the Galactic disk
We report the detection of a cold Neptune m(planet) 21 2M(circle plus) orbiting a 0.38M(circle dot) M dwarf lying 2.5 3.3 kpc toward the Galactic center as part of a campaign combining ground based and Spitzer observations to measure the Galactic distribution of planets. This is the first time that the complex real time protocols described by Yee et al. which aim to maximize planet sensitivity while maintaining sample integrity, have been carried out in practice. Multiple survey and follow. up teams successfully combined their efforts within the framework of these protocols to detect this planet. This is the second planet in the Spitzer Galactic distribution sample. Both are in the near. to. mid disk and are clearly not in the Galactic bulge.
