Search for exoplanets in M31 with pixel-lensing and the PA-99-N2 event revisited [PDF]
, 2010 Several exoplanets have been detected towards the Galactic bulge with the microlensing technique. We show that exoplanets in M31 may also be detected with the pixel-lensing method, if telescopes making high cadence observations of an ongoing microlensing

Exploring the Impact of Microlensing on Gravitational Wave Signals: Biases, Population Characteristics, and Prospects for Detection [PDF]
, 2023 In this study, we investigate the impact of microlensing on gravitational wave (GW) signals in the LIGO$-$Virgo sensitivity band. Microlensing caused by an isolated point lens, with (redshifted) mass ranging from $M_\mathrm{Lz}\in(1,10^5){\rm M}_\odot ...

Improving Detection of Gravitational-wave Microlensing Using Repeated Signals Induced by Strong Lensing [PDF]
Astrophysical Journal, 2021 Microlensing imprints by typical stellar-mass lenses on gravitational waves are challenging to identify in the LIGO–Virgo frequency band because such effects are weak.

Free-floating Planet Mass Function from MOA-II 9 yr Survey toward the Galactic Bulge
The Astronomical Journal, 2023 We present the first measurement of the mass function of free-floating planets (FFPs), or very wide orbit planets down to an Earth mass, from the MOA-II microlensing survey in 2006–2014.

Exoplanets - search methods, discoveries, and prospects for astrobiology [PDF]
, 2008 Whereas the Solar System has Mars and Europa as the best candidates for finding fossil/extant life as we know it - based on complex carbon compounds and liquid water - the 263 (non-pulsar) planetary systems around other stars as known at 15 September ...

Probing the Spatial Distribution of Extrasolar Planets with Gravitational Microlensing [PDF]
, 2003 To search for extrasolar planets, current microlensing follow-up experiments are monitoring events caused by stellar-mass lenses, hoping to detect the planet's signature of the short-duration perturbation in the smooth lensing light curve of the primary.

Confirmation of Color-dependent Centroid Shift Measured After 1.8 Years with HST
The Astronomical Journal, 2023 We measured the precise masses of the host and planet in the OGLE-2003-BLG-235 system, when the lens and source were resolving, with 2018 Keck high resolution images.

Planetary mass function and planetary systems [PDF]
, 2010 With planets orbiting stars, a planetary mass function should not be seen as a low-mass extension of the stellar mass function, but a proper formalism needs to take care of the fact that the statistical properties of planet populations are linked to the ...
