High-cadence observations of the Galactic bulge by the microlensing surveys led to the discovery of a handful of extremely short-timescale microlensing events that can be attributed to free-floating or wide-orbit planets. Here, we report the discovery of another strong free-floating planet candidate, which was found from the analysis of the gravitational microlensing event OGLE-2019-BLG-0551. The light curve of the event is characterized by a very short duration (<3 d) and a very small…

A Terrestrial-mass Rogue Planet Candidate Detected in the Shortest-timescale Microlensing Event
Some low-mass planets are expected to be ejected from their parent planetary systems during early stages of planetary system formation. According to planet-formation theories, such as the core

We report the discovery and analysis of the planetary microlensing event OGLE-2017-BLG-0406, which was observed both from the ground and by the ${\it Spitzer}$ satellite in a solar orbit. At high
The fate of binary stars hosting planets upon interaction with Sgr A* black hole
Our Galaxy hosts a very massive object at its centre, often referred to as the supermassive black hole Sgr A*. Its gravitational tidal field is so intense that it can strip apart a binary star
The Demographics of Wide-Separation Planets
I begin this review by first defining what is meant by exoplanet demographics, and then motivating why we would like as broad a picture of exoplanet demographics as possible. I then outline the
Exoplanets as New Sub-GeV Dark Matter Detectors
We present exoplanets as new targets to discover Dark Matter (DM), with advantages due to their large expected abundance, low temperatures, and large sizes. Throughout the Milky Way, DM can scatter,
KMT-2017-BLG-2820 and the Nature of the Free-floating Planet Population
We report a new free-floating planet (FFP) candidate, KMT-2017-BLG-2820, with Einstein radius θ E ≃ 6 μas, lens-source relative proper motion μ rel ≃ 8 mas yr−1, and Einstein timescale t E = 6.5 hr.
A Multiparameter Degeneracy in Microlensing Events with Extreme Finite Source Effects
For microlenses with sufficiently low mass, the angular radius of the source star can be much larger than the angular Einstein ring radius of the lens. For such extreme finite source effect (EFSE)
Using Source Proper Motion to Validate Terrestrial Parallax: OGLE-2019-BLG-1058
We show that because the conditions for producing terrestrial microlens parallax (TPRX; i.e., a nearby disk lens) will also tend to produce a large lens-source relative proper motion (μ rel), source

No large population of unbound or wide-orbit Jupiter-mass planets
TLDR
A sample of microlensing events six times larger than that of ref. 11 is analysed, finding no excess of events with timescales in this range, with a 95 per cent upper limit on the frequency of Jupiter-mass free-floating or wide-orbit planets of 0.25 planets per main-sequence star.
