With high enough temporal resolution even the angular size of thebackgroundstarcan be determined.
From
Wikipedia
To find planets using that method, thebackgroundstaris temporarily magnified by a foreground star because of the gravity that bends light.
From
Wikipedia
If the foreground star has a planet, the light frombackgroundstarwould be slightly brighter than the star with no planet.
From
Wikipedia
Studying the brightness difference ofbackgroundstarbetween the foreground star with planets and foreground star with no planets, then mass can be estimated.
From
Wikipedia
When a planetary-sized object passes in front of abackgroundstar, its gravitational field causes a momentary increase in the visible brightness of thebackgroundstar.
From
Wikipedia
For definiteness, we assume that background stars are ten times more distant than the target star.
From theCambridge English Corpus
First, although the fields of view contain typically many stars besides the target star, these background stars are also much more distant.
From theCambridge English Corpus
One potential problem - possible confusion from background stars, particularly eclipsing binaries near the line of sight to a foreground target star - is addressed here.
From theCambridge English Corpus
This increases the risk of degraded photometric accuracy due to background stars.
From theCambridge English Corpus
This conclusion holds both for the case of background stars in the field of view of the target star and from objects (such as planets) orbiting the target star.
From theCambridge English Corpus
In particular, the lower limit of its 1.653.8 m color of 3.1 magnitudes excludes background stars and most brown dwarfs.
From
Wikipedia
It is therefore possible that the two background stars are bound, but it is not certain.
From
Wikipedia
Alternatively, when the satellite is in sunlight, it can be photographed against the background stars.
From
Wikipedia
The concentration of dust within molecular cores is normally sufficient to block light from background stars so that they appear in silhouette as dark nebulae.
From
Wikipedia
By studying these images, they can detect solar system objects by their movements relative to the background stars, which remain fixed.
From
Wikipedia
This survey only covered a portion of the ecliptic about the vernal equinox, with the target areas selected to minimize the number of background stars.
From
Wikipedia
It is projected in front of the galactic bulge and is therefore useful for its microlensing effect on the background stars in the bulge.
From
Wikipedia
Of the two fundamental planes, the ecliptic is closer to unmoving against the background stars, its motion due to planetary precession being roughly 1/100 that of the celestial equator.
