„Temperament“ Sterne können Exoplanet -Beobachtungen verzerren

>a new study, published in The Astrophysical Journal Supplement, concluded that fluctuations in the starlight due to hotter and colder regions on a star’s surface may be distorting our interpretations of planets more than we previously thought.
The researchers looked at the atmospheres of 20 Jupiter- and Neptune-sized planets and found that the host stars‘ changeability distorted the data for about half of them.

>If researchers did not properly account for these variations, the team said, they could misinterpret a range of features such as the planets‘ size, temperature and the composition of their atmospheres. The team added that the risk of misinterpretation was manageable if researchers looked at a range of wavelengths of light, including in the optical region where effects of stellar contamination are most apparent.
