Sirius B-studie fr\u00e5n Malm\u00f6<\/h2>\n\n\n\n

H\u00e4rom kv\u00e4llen lyckades Hans Hilderfors <\/strong>fr\u00e5n sitt obsis i Malm\u00f6 dokumentera Sirius lilla,vita dv\u00e4rgsolsgranne Sirius B, ungef\u00e4r vid klockan 10 p\u00e5 gif-animationen. Ljusstyrkef\u00f6rh\u00e5llandet Sirius A vs Sirius B \u00e4r ungef\u00e4r 10 000\/1. Storleksm\u00e4ssigt p\u00e5st\u00e5s Sirius B vara i jordklotets dimension.<\/p>\n\n\n\n

Uppt\u00e4ckten av Sirius B tillh\u00f6r 1800-talets st\u00f6rre uppt\u00e4ckter, tycker vi. Alvan Clarke<\/strong> testade ett av sina nytillverkade teleskop 1862 och fick syn p\u00e5 stj\u00e4rnan, som vi i dag vet var den andra vita dv\u00e4rgstj\u00e4rna som \u00f6verhuvud taget identifierats.<\/p>\n\n\n\n

Jakten p\u00e5 eventuella planet\u00e4ra f\u00f6ljeslagare till Sirius B har inte gett resultat.<\/a><\/p>\n\n\n\n

Sirius forts\u00e4tter att utmana oss \u00f6verhuvud taget. Det \u00e4r bara sju \u00e5r sedan en ok\u00e4nd stj\u00e4rnhop kallad Gaia 1 uppt\u00e4cktes “bakom” Sirius. Tekniken var at maska Sirius ljus s\u00e5 mycket som m\u00f6jligt.<\/p>\n\n\n
