Spitzer Parallax of OGLE-2015-BLG-0966: A Cold Neptune in the Galactic Disk
Publikation: Bidrag til tidsskrift › Tidsskriftartikel › Forskning › fagfællebedømt
We report the detection of a cold Neptune mplanet = 21
± 2 M⊕ orbiting a 0.38 M⊙ 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.
