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. This gravitational lensing technique is the only method employing currently available technology that can detect Earth-mass planets at high signal-to-noise, and can measure the abundance of terrestrial planets as a function of Galactic position. GEST's sensitivity extends down to the mass of Mars, and it can detect… 

Studying planet populations by gravitational microlensing

The ‘most curious’ effect of the bending of light by the gravity of stars has evolved into a successful technique unlike any other for studying planets within the Milky Way and even other galaxies.

Predictions of the WFIRST Microlensing Survey. I. Bound Planet Detection Rates

The Wide Field InfraRed Survey Telescope (WFIRST) is the next NASA astrophysics flagship mission, to follow the James Webb Space Telescope. The WFIRST mission was chosen as the top-priority large

Detection of exoplanet as a binary source of microlensing events in WFIRST survey

We investigate the possibility of exoplanet detection orbiting source stars in microlensing events through WFIRST observations. We perform a Monte Carlo simulation on the detection rate of

On detecting terrestrial planets with timing of giant planet transits

The transits of a distant star by a planet on a Keplerian orbit occur at time intervals exactly equal to the orbital period. If a second planet orbits the same star, the orbits are not Keplerian and


The Korean Microlensing Telescope Network (KMTNet) will consist of three 1.6 m telescopes each with a 4 deg2 field of view (FoV) and will be dedicated to monitoring the Galactic Bulge to detect

Compact object detection in self-lensing binary systems with a main-sequence star

Detecting compact objects such as black holes, white dwarfs, strange (quark) stars and neutron stars by means of their gravitational lensing effect on an observed companion in a binary system has

Science Yield of an Improved Wide Field Infrared Survey Telescope (WFIRST)

The Astronomy and Astrophysics Decadal Survey's highest recommended space mission was a Wide-Field Infrared Survey Telescope (WFIRST) to efficiently conduct three kinds of studies: dark energy

Detecting New Planets in Transiting Systems

I present an initial investigation into a new planet detection technique that uses the transit timing of a known, transiting planet. The transits of a solitary planet orbiting a star occur at equally

Simulation of a Space-based Microlensing Survey for Terrestrial Extrasolar Planets

We show that a space-based gravitational microlensing survey for terrestrial extrasolar planets is feasible in the near future and could provide a nearly complete picture of the properties of

Discovering Planetary Systems through Gravitational Microlenses

Planetary systems of Galactic disk stars can be detected as microlenses of stars in the Galactic bulge. Planets in a solar-like system positioned half-way to the Galactic center should leave a

Limits on the Abundance of Galactic Planets From 5 Years of PLANET Observations

We search for signatures of planets in 43 intensively monitored microlensing events that were observed between 1995 and 1999. Planets would be expected to cause a short-duration (~1 day) deviation on

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

Gravitational Microlensing Evidence for a Planet Orbiting a Binary Star System

The study of extra-solar planetary systems has emerged as a new discipline of observational astronomy in the past few years with the discovery of a number of extra-solar planets. 1 , 2 The properties

Discovery of a planet orbiting a binary star system from gravitational microlensing

The properties of the recently discovered extrasolar planets were not anticipated by theoretical work on the formation of planetary systems, most models for which were developed to explain our Solar

Gravitational microlensing by double stars and planetary systems

Almost all stars are in binary systems. When the separation between the two components is comparable to the Einstein ring radius corresponding to the combined mass of the binary acting as a


Abstract The statistical distribution of the masses of planets about stars between the Sun and the center of the Galaxy is constrained to within a factor of 3 by an intensive search for planets

Discovering Galactic planets by gravitational microlensing: magnification patterns and light curves

The current searches for microlensing events towards the galactic bulge can be used to detect planets around the lensing stars. Their effect is a short-term modulation on the smooth lightcurve

Planets Orbiting Other Suns

After a century fraught with false claims, evidence for planets around other stars finally appears robust. Infrared imaging and spectroscopy of disks around stars foreshadow detailed models of the
