We study the possibility to detect extrasolar planets in M31 through pixel-lensing observations. Using a Monte Carlo approach, we select the physical parameters of the binary lens system, a star hosting a planet, and we calculate the pixel-lensing light curve taking into account the finite source effects. Indeed, their inclusion is crucial since the sources in M31 microlensing events are mainly giant stars. Light curves with detectable planetary features are selected by looking for significant… 
Search for exoplanets in M31 with pixel-lensing and the PA-99-N2 event revisited
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
Accurate Mass Measurements for Planetary Microlensing Events Using High Angular Resolution Observations
The microlensing technique is a unique method to hunt for cold planets over a range of mass and separation, orbiting all varieties of host stars in the disk of our galaxy. It provides precise
New Self-lensing Models of the Small Magellanic Cloud: Can Gravitational Microlensing Detect Extragalactic Exoplanets?
We use three-dimensional distributions of classical Cepheids and RR Lyrae stars in the Small Magellanic Cloud (SMC) to model the stellar density distribution of a young and old stellar population in
Polarization in microlensing events towards the Galactic bulge
Gravitational microlensing, when finite size source effects are relevant, provides a unique tool for the study of source star stellar atmospheres through an enhancement of a characteristic
Searching for Extragalactic Exoplanetary Systems: The Curious Case of BD+20 2457
Planets and their host stars carry a long-term memory of their origin in their chemical compositions. Thus, identifying planets formed in different environments improves our understating of planetary
Exoplanetary Microlensing
Gravitational microlensing occurs when a foreground star h appens to pass very close to our line of sight to a more distant background star. The foreground st ar acts as a lens, splitting the light
Polarization in binary microlensing events
The light received by source stars in microlensing events may be significantly polarized if both an efficient photon-scattering mechanism is active in the source stellar atmosphere and a differential
Confirmation of Planet-mass Objects in Extragalactic Systems
Quasar microlensing serves as a unique probe of discrete objects within galaxies and galaxy clusters. Recent advancement of the technique shows that it can constrain planet-scale objects beyond our
Realisation of a fully-deterministic microlensing observing strategy for inferring planet populations
Within less than 15 years, the count of known planets orbiting stars other than the Sun has risen from none to more than 400 with detections arising from four successfully applied techniques:
Measuring polarization in microlensing events
We reconsider the polarization of the star light that may arise during microlensing events due to the high gradient of magnification across the atmosphere of the source star, by exploring the full


Detecting Earth-Mass Planets with Gravitational Microlensing
We show that Earth-mass planets orbiting stars in the Galactic disk and bulge can be detected by monitoring microlensed stars in the Galactic bulge. The star and its planet act as a binary lens which
The Possibility of Detecting Planets in the Andromeda Galaxy
The Angstrom project is using a global network of 2 m class telescopes to conduct a high-cadence pixel microlensing survey of the bulge of the Andromeda galaxy (M31), with the primary aim of
The Use of High-Magnification Microlensing Events in Discovering Extrasolar Planets
Hundreds of gravitational microlensing events have now been detected toward the Galactic bulge, with many more to come. The detection of fine structure in these events has been theorized as an
Binary Events and Extragalactic Planets in Pixel Microlensing
Pixel microlensing, i.e., gravitational microlensing of unresolved stars, can be used to explore distant stellar systems and, as a bonus, may be able to detect extragalactic planets. In these
POINT-AGAPE pixel lensing survey of M31: Evidence for a MACHO contribution to galactic halos
The POINT-AGAPE collaboration is carrying out a search for gravitational microlensing toward M31 to reveal galactic dark matter in the form of MACHOs (Massive Astrophysical Compact Halo Objects) in
Planet Parameters in Microlensing Events
A planetary microlensing event occurs when a planet perturbs one of the two images created in a point-mass microlensing event, causing a deviation from the standard Paczyński curve. Determination of
A Jovian-Mass Planet in Microlensing Event OGLE-2005-BLG-071
We report the discovery of a several-Jupiter-mass planetary companion to the primary lens star in microlensing event OGLE-2005-BLG-071. Precise (≲1%) photometry at the peak of the event yields an

Gravitational lensing – i.e. light deflection by gravity – has become an important tool for exploring our Universe, in particular to determine its matter content. There are cases in which the
We report the detection of the cool, Jovian-mass planet MOA-2007-BLG-400Lb. The planet was detected in a high-magnification microlensing event (with peak magnification Amax = 628) in which the
Theory of pixel lensing towards M31 - I. The density contribution and mass of MACHOs
POINT–AGAPE is an Anglo-French collaboration which is employing the Isaac Newton Telescope (INT) to conduct a pixel-lensing survey towards M31. Pixel lensing is a technique which permits the
