Parallax

, 2013
For the uninitiated, parallax is a fancy term for triangulation, which we humans naturally do in the form of depth perception – your eyes are separated by a small distance from each other so they see slightly different views of the world.

KMT-2023-BLG-2669: Ninth Free-floating Planet Candidate with θ E Measurements

The Astronomical Journal
We report a free-floating planet (FFP) candidate identified from the analysis of the microlensing event KMT-2023-BLG-2669. The lensing light curve is characterized by a short duration (≲3 days) and a small amplitude (≲0.7 mag). From the analysis, we find

Constraining galactic models through parallax and astrometry of microlensing events

, 2005
Various models for the Galactic distribution of massive compact halo objects (MACHOs) have been proposed for the interpretation of microlensing toward the Large Magellanic Cloud (LMC).

Removing the microlensing blending-parallax degeneracy using source variability

, 2006
Microlensing event MACHO 97-SMC-1 is one of the rare microlensing events for which the source is a variable star, simply because most variable stars are systematically eliminated from microlensing studies. Using observational data for this event, we show

OGLE-2016-BLG-0168 Binary Microlensing Event: Prediction and Confirmation of the Microlens Parallax Effect from Space-based Observations [PDF]

, 2017
The microlens parallax is a crucial observable for conclusively identifying the nature of lens systems in microlensing events containing or composed of faint (even dark) astronomical objects such as planets, neutron stars, brown dwarfs, and black holes ...
