Orbiting too close to its parent star, this young gas giant unleashes violent <strong>bursts of energy<\/strong> that damage it, <strong>slowly corroding its atmosphere<\/strong>.<\/p>\n\n\n\n<p><strong>A Planet Influencing Its Star<\/strong><\/p>\n\n\n\n<p>Published in the prestigious magazine <em>Nature<\/em>, the discovery of Hip 67522 b represents a unique case in the history of astronomy: <strong>is the first planet known to actively influence its star<\/strong>, and not vice versa, as has always been believed. A real reversal of the rules in the relationship between star and planet.<\/p>\n\n\n\n<p><strong>The Hunt for Exoplanets that Trigger Starbursts<\/strong><\/p>\n\n\n\n<p>Since the discovery of the first <strong>exoplanets<\/strong> in the 1990s, scientists wondered if some of them could orbit so close to their star as to <strong>disrupt its magnetic field<\/strong>, causing violent flares.<\/p>\n\n\n\n<p>To answer this question, a team led by <strong>Ekaterina Ilin<\/strong> of the Dutch Institute of Radio Astronomy analysed data from the space telescope <strong>TESS<\/strong> by NASA, identifying stars with <strong>flare<\/strong> potentially triggered by planets. One of the most interesting cases? The very young star <strong>Hip 67522<\/strong>, with just 17 million years and two planets in orbit.<\/p>\n\n\n\n<p><strong>Cheops Confirms: Planet Triggers Flares<\/strong><\/p>\n\n\n\n<p>To confirm the hypothesis, the researchers involved the telescope <strong>Cheops<\/strong>, specialising in high-precision observation of single stars. During the <strong>transits<\/strong> of the planet in front of the star, Cheops detected well <strong>15 flares<\/strong>a clear signal that these events are <strong>caused by the very presence of the planet<\/strong>.<\/p>\n\n\n\n<p><strong>A Gas Giant Destined to Disappear<\/strong><\/p>\n\n\n\n<p><strong>Hip 67522 b<\/strong> is located about <strong>400 light years from Earth<\/strong> and is a <strong>gas giant<\/strong> with a size similar to Jupiter, but a surprisingly low density - comparable to that of candyfloss. The star's radiation is <strong>eroding its fragile atmosphere<\/strong>, bringing it to <strong>lose mass much more quickly<\/strong> than expected. If the pace of <strong>atmospheric evaporation<\/strong> will continue, in about <strong>100 million years<\/strong> this planet could be reduced to a <strong>miniaturised version<\/strong>, similar or even smaller than <strong>Neptune<\/strong>.<\/p>","protected":false},"excerpt":{"rendered":"<p>Un team internazionale di astronomi ha scoperto, grazie alla missione Cheops dell\u2019Agenzia Spaziale Europea (ESA), un esopianeta davvero sorprendente: si chiama Hip 67522 b e si sta, letteralmente, autodistruggendo.
