Noisy star masks planet's true size
Astronomers observing exoplanets around other stars may be
underestimating their size, according to a German study.
The researchers believe the error may be due to active stars adding 'noise'
to the observation of exoplanets using the transit method.
Their study appears on the electronic preprint website arXiv.
The transit method detects exoplanets as they pass in front of their parent
star, reducing the amount of light reaching telescopes on, and orbiting,
Earth.
