Hvordan ser det ud inde i k\u00e6mpestjerner og dv\u00e6rgstjerner? Disse to meget forskellige sp\u00f8rgsm\u00e5l vil snart blive besvaret af et unikt europ\u00e6isk rumteleskop ved navn COROT.<\/p>\n<\/div>\n<p>COROT, der forventes at blive opsendt i december 2006, bliver det f\u00f8rste rumfart\u00f8j, der udelukkende er dedikeret til at lede efter planeter, der kredser om fjerne stjerner. S\u00e5danne planeter er normalt skjult i deres stjernes bl\u00e6ndende lys og umulige at se. COROT l\u00f8ser dette problem ved at lede efter et ubetydeligt fald i stjernelyset, der skyldes, at en planet passerer foran sin moderstjerne.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"3330\" data-credit=\"ESO\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2006\/03\/Exoplanet2\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2006\/03\/exoplanet2\/17906718-2-eng-GB\/Exoplanet.jpe\" alt=\"\"><\/figure>\n<p>Ved at unders\u00f8ge \u2018svingninger\u2019 i fjerne stjerner har astronomer fundet indirekte beviser for mere end 200 planeter uden for vores solsystem. N\u00e6sten alle er dog gasgiganter, der er langt st\u00f8rre end Jorden. COROT forventes at finde mange flere af disse \u2018varme Jupiter-planeter\u2019. Men nogle af de planeter, som COROT har opdaget, forventes kun at v\u00e6re lidt st\u00f8rre end Jorden.<\/p>\n<p>COROT er mest f\u00f8lsom over for sm\u00e5 planeter med oml\u00f8bstider p\u00e5 50 dage eller derunder. Det vil sige, at de befinder sig t\u00e6ttere p\u00e5 deres moderstjerne, end Merkur er p\u00e5 Solen, med temperaturer, der er for h\u00f8je til, at der kan eksistere liv \u2013 medmindre stjernen er en k\u00f8lig r\u00f8d dv\u00e6rg.<\/p>\n<p>I l\u00f8bet af sin to og et halvt \u00e5r lange mission vil COROT ogs\u00e5 unders\u00f8ge \u00e6ndringer i lysudbyttet fra tusindvis af stjerner. Dets specielle kamera vil registrere sm\u00e5 variationer i lysstyrken, der skyldes stjernejordsk\u00e6lv \u2013 lydb\u00f8lger, der breder sig hen over overfladen. Disse vil give forskerne indsigt i, hvordan forholdene er inde i stjernen.<\/p>","protected":false},"excerpt":{"rendered":"<p>Are there any small, Earthlike planets orbiting distant stars?
