Astronomii au măsurat câmpurile magnetice ale unor planete unde vântul bate cu peste 25.000 km/h. „Este complet contraintuitiv”
Planete din categoria „Jupiter fierbinte” - gigante gazoase cu temperaturi de aproximativ 2.000 de grade Celsius - au câmpuri magnetice comparabile cu cele ale planetelor mult mai reci din Sistemul Solar, au descoperit oamenii de știință, care întrevăd noi perspective pentru cercetarea exoplanetelor.
Astronomers have measured the magnetic fields of "hot Jupiter" exoplanets, which are gas giants reaching temperatures around 2,000 degrees Celsius. Surprisingly, these extremely hot worlds possess magnetic fields comparable in strength to those found on much cooler planets within our own Solar System. This finding challenges previous assumptions about planetary magnetic field generation and behavior under such intense thermal conditions. The research opens new avenues for understanding the diverse magnetic environments of planets beyond our solar system.
This discovery provides unexpected insights into the complex processes governing planetary magnetic fields, potentially altering our models of exoplanet formation and evolution.
