gravitational microlensing

For their investigation, astronomers turned to gravitational microlensing, since dark matter cannot be seen directly.

However, an alternate approach can be employed that makes use of gravitational microlensing events.

When the two objects are stars, as opposed to galaxies, it is called gravitational microlensing.

This is the first planetary system where more than one planet was detected using gravitational microlensing.

In 2008, two extrasolar planets were discovered around the star using gravitational microlensing.

Gravitational microlensing has been used to measure the mass of a single star.)

The researchers used a technique called gravitational microlensing to detect these homeless planets.

These objects can be detected using gravitational microlensing.

A solar system similar to ours is discovered 5,000 light-years away by an international team of scientists using gravitational microlensing.

The new work was done using a method known as gravitational microlensing, which is more sensitive to far-out planets.

"Gravitational microlensing by low-mass objects in the globular cluster M22."

Others have been detected via gravitational microlensing, for which only the mass ratio between the planet and the parent star is known.

Its discovery was announced on February 21, 2011, making it the eleventh planet discovered using gravitational microlensing.

Two methods to detect rogue planets still can be used: gravitational microlensing and direct imaging.

However, the addition of another technique, gravitational microlensing, promises to find worlds down to 10 Earth masses, much further out from their parent stars.

In 2006, an Uranus-mass extrasolar planet was detected by gravitational microlensing around this star.

Gravitational microlensing is an astronomical phenomenon due to the gravitational lens effect.

Gravitational microlensing and the search for extra-solar planets.

Gaudi and his team determined the mass of the planets by calculating how the light changed, a technique called gravitational microlensing.

It was detected by gravitational microlensing.

The team used gravitational microlensing to discover the gravitational effects of planets orbiting distant stars.

This planet was detected on September 18, 2008 by the gravitational microlensing by Dong.

According to the Extrasolar Planet Encyclopaedia, astronomers have discovered 13 planets using gravitational microlensing.

The simultaneous discovery of two planets is rare and this was the first time researchers had the opportunity to do so using a technique called gravitational microlensing.

The astronomers performing that previous study used a method called gravitational microlensing, which only works when a planet-hosting star happens to line up with another star.
