The European Space Agency's Gaia telescope was originally designed to create a detailed map
The researchers tried to usethe accumulated data of the telescope for the search for exoplanets. Such a task was not originally set, however, as it turned out, the experiment led to positive results. You can detect an exoplanet by the movement of a star that fluctuates in the sky under the influence of the planet's gravity.
Scientists collected photometric data obtainedall Gaia tools. These data were processed by a special algorithm trained on the results of the study of exoplanets by the TESS telescope, which specializes in exoplanets.
In the collected data, the researchers found howat least two hot Jupiters - Gaia-1b and Gaia-2b, which have already been confirmed by TESS, and 41 more possible exoplanet candidates that need additional verification.
Scientists note that two telescopes usedifferent principles: Gaia covers the whole sky, but rarely studies the same star, TESS - concentrates on specific stars for a long time. Combining data from these instruments could help find new exoplanets.
