Gaia22dkvLb: A Microlensing Planet Potentially Accessible to Radial-velocity Characterization

The Astronomical Journal
We report discovering an exoplanet from following up a microlensing event alerted by Gaia. The event Gaia22dkv is toward a disk source rather than the traditional bulge microlensing fields. Our primary analysis yields a Jovian planet with ${M}_{{\rm{p}}}=

The Galactic Exoplanet Survey Telescope (GEST)

, 2002
The Galactic Exoplanet Survey Telescope (GEST) will observe a 2 square degree field in the Galactic bulge to search for extra-solar planets using a gravitational lensing technique.

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

A Sub-Saturn Mass Planet, MOA-2009-BLG-319Lb [PDF]

, 2011
We report the gravitational microlensing discovery of a sub-Saturn mass planet, MOA-2009-BLG-319Lb, orbiting a K- or M-dwarf star in the inner Galactic disk or Galactic bulge.

Evaluation and Demonstration of the Principle and Results for Different Planet Searching and Detection Schemes

Highlights in Science Engineering and Technology
As a matter of fact, exoplanets searching are crucial for human beings for not only searching for new habitats but also for understanding of celestial evolution. In retrospect, the field of exoplanet detection officially initiated in 1992, when the first

Investigating the Binary Source Degeneracy for Wide-orbit Planets

The Astronomical Journal
Wide-orbit planets are particularly sensitive to detection by the Roman Galactic Bulge Time Domain Survey (GBTDS). This study investigates the degeneracy of these events with binary sources, focusing on how observation cadence affects the resolution of ...

Inferring statistics of planet populations by means of automated microlensing searches [PDF]

, 2008
(abridged) The study of other worlds is key to understanding our own, and not only provides clues to the origin of our civilization, but also looks into its future. Rather than in identifying nearby systems and learning about their individual properties,

Microlensing Searches for Exoplanets

, 2018
Gravitational microlensing finds planets through their gravitational influence on the light coming from a more distant background star. The presence of the planet is then inferred from the tell-tale brightness variations of the background star during the

How Rare Are TESS Free-floating Planets?

The Astrophysical Journal Letters
Recently, Kunimoto et al. claimed that a short-lived signal in the Transiting Exoplanet Survey Satellite (TESS) Sector 61 database was possibly caused by a microlensing event with a terrestrial-mass free-floating planet (FFP) lens.

EUCLID : Dark Universe Probe and Microlensing planet Hunter

, 2010
There is a remarkable synergy between requirements for Dark Energy probes by cosmic shear measurements and planet hunting by microlensing. Employing weak and strong gravitational lensing to trace and detect the distribution of matter on cosmic and ...
