Hallaron que la causa es la combinación de una estrella compañera cercana, enormes manchas oscuras en su superficie y un mecanismo magnético interno muy eficiente.","fuente":"phys","fuenteNombre":"Phys.org","color":"#2b5c8a","autor":"","url":"https://phys.org/news/2026-10-astronomers-uncover-powerful-stellar-flares.html","imagen":"https://scx1.b-cdn.net/csz/news/tmb/2026/astronomers-uncover-th.jpg","tema":"ciencia","subtemas":["astronomia","estrellas gigantes rojas","campos magneticos estelares","telescopio kepler","llamaradas estelares"],"entidades":["Observatorio Konkoly","HUN-REN CSFK","Budapest","Kepler"],"formato":"dato","entretenimiento":false,"pubTs":"2026-10-21T13:20:06.000Z","indexTs":"2026-10-21T13:21:40.828Z","hash":"5c7a03069ade231f3502ce45c42b5aac57a6cddc4457925e5bff40af58539144","tsa":{"time":"Oct 21 13:22:22 2026 GMT","provider":"freetsa.org","sobre":"sello"},"stats":{"views":0,"likes":0,"clicks":0,"dwell":0},"tipo":"motor","registro":"hallazgo","porQueImporta":"La explicación combina tres factores: una compañera cercana, manchas oscuras gigantes y un generador magnético interno muy eficiente que, juntos, producen las llamaradas más intensas del campo. Para el público argentino, el valor está en entender cómo funcionan los astros que vemos en el cielo sin que afecten la vida cotidiana de acá. Es una pista de que incluso en estrellas lejanas, un vecino cercano puede cambiarlo todo.","quienFirma":"Observatorio Konkoly, HUN-REN CSFK (Budapest)","confianza":"preprint","consulta":{"pregunta":"¿Te interesa saber más sobre cómo se forman las estrellas y sus explosiones?"}},"sello":{"hash":"5c7a03069ade231f3502ce45c42b5aac57a6cddc4457925e5bff40af58539144","sello":"092c3eebb7d86788ad9ef8acc3eaaf2905c92fd5d9502942f3b784b7b132b0f3","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6571930,"aleatorio":"11c763cb62cf5103f1e48ad9ffaba165e2cb7f212f5b7adf0ed59d3dcdb14edd","tiempo":"2026-10-21T13:22:00.000Z"},"nist":{"cadena":2,"pulso":1993170,"salida":"8256076CBD85D4E86A2BE000C26B9CF615BBA57FAC45C6B5E9852EE34C0B0B9CC895961828AC303F9E62954B60F47BD242C03D0B781A7B6034F2A914A075B817","tiempo":"2026-10-21T13:21:00.000Z"},"noAntes":"2026-10-21T13:22:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 21 13:22:22 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Astronomers uncover the engine behind the most powerful stellar flares in the Kepler field","descripcion":"A new study led by researchers at the Konkoly Observatory of the HUN-REN Research Centre for Astronomy and Earth Sciences (HUN-REN CSFK) in Budapest has revealed what makes a distant red giant star the most explosively active in the entire Kepler field—and the answer lies in a surprisingly subtle interplay between a close stellar companion, vast dark starspots and a highly efficient internal magnetic dynamo.","pubDate":"Wed, 21 Oct 2026 09:20:06 EDT","url":"https://phys.org/news/2026-10-astronomers-uncover-powerful-stellar-flares.html"},"indexado":"2026-10-21T13:21:40.828Z"}}
