A Spitzer telescope review of microlensing events led scientists to find a massive planet around a star that lives in the convexity of the Milky Way. The planet was designated as OGLE-2016-BLG-1190Lb and this is the first alien world found in the bulge.
Microlensing is a useful method for finding other worlds in the inner galactic disk and bulges where other technologies fail. Background stars are used as pointers. If one star passes before the second, then the light distantly bends by the gravity of the first and increases.
OGLE-2016-BLG-1190 was recorded in June 2016 in cooperation with the gravitational experiment OGLE. This is a Polish project of the Warsaw University, concentrating on the search for dark matter and exoplanets. To do this, use the 1.3-meter telescope of the Las Campanas Observatory (Chile). Spitzer captured a microlensing event a few days after opening. OGLE-2016-BLG-1190Lb is an extremely massive world, whose mass is 13.4 times larger than the Jupiter index. This brings the planet to the line between the planetary object and the transition to the brown dwarf. Therefore, it may be a low-mass brown dwarf.
The exoplanet is 2 stars away from the star. e. and spends on one flyby 3 years. The host star is a G-type dwarf, distant by 22,000 light years from us. The study of the planet is important not only because of its location, but also to understand whether to call such objects planets or unsuccessful stars.
