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 ...

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 ...

The Observational Case for Jupiter Being a Typical Massive Planet

, 2002
We identify a subsample of the recently detected extrasolar planets that is minimally affected by the selection effects of the Doppler detection method.

LensNet: Enhancing Real-time Microlensing Event Discovery with Recurrent Neural Networks in the Korea Microlensing Telescope Network

The Astronomical Journal
Traditional microlensing event vetting methods require highly trained human experts, and the process is both complex and time consuming. This reliance on manual inspection often leads to inefficiencies and constrains the ability to scale for widespread ...

The First Neptune Analog or Super-Earth with Neptune-like Orbit: MOA-2013-BLG-605Lb

, 2016
We present the discovery of the first Neptune analog exoplanet or super-Earth with Neptune-like orbit, MOA-2013-BLG-605Lb. This planet has a mass similar to that of Neptune or a super-Earth and it orbits at $9\sim 14$ times the expected position of the ...

The Search for Exoplanets: Methods and History

International Journal For Multidisciplinary Research
The discovery of exoplanets, planets beyond the solar system, has raised key questions about extraterrestrial life and the technology needed to find it. While considerable progress in exoplanet detection has been achieved over the past three decades, the

Fractal Algorithm for Multiple-lens Analyses

The Astrophysical Journal
A microlensing exoplanet search is a unique method for finding planets orbiting distant stars. However, in the past, the method used to analyze microlensing data could not deal with complex lens systems. The number of lenses was limited to three or less.

Systematic Reanalysis of KMTNet Microlensing Events. II. Two New Planets in Giant-source Events

The Astronomical Journal
In this work, we continue to apply the updated KMTNet tender-love care photometric pipeline to historical microlensing events. We apply the pipeline to a subsample of events from the KMTNet database, which we refer to as the giant source sample ...
