Den statliga korporationen Roscosmos och P.N. Lebedev Institute of Physics vid Rysslands vetenskapsakademi (FIAN) presenterade projektet «Musik av pulsarer».<\/p>\n

\"\u00abMusik<\/p>\n

Pulsarer \u00e4r snabbt roterande neutronstj\u00e4rnor med extremt h\u00f6g densitet. De har en rotationsperiod och en viss modulering av den str\u00e5lning som n\u00e5r jorden.<\/p>\n

Pulsarsignaler kan anv\u00e4ndas som tidsetaloner och riktm\u00e4rken f\u00f6r satelliter, och genom att omvandla deras frekvens till ljudv\u00e5gor kan man f\u00e5 en slags musik. Precis s\u00e5dan «melodi» skapade de ryska specialisterna.<\/p>\n

F\u00f6r att skapa «musiken» anv\u00e4ndes data fr\u00e5n det orbitala teleskopet «Spektr-R». Denna enhet, tillsammans med jordbaserade radioteleskop, bildade en radiainterferometer med en mycket stor bas \u2014 grunden f\u00f6r det internationella projektet «Radioastron». Teleskopet sk\u00f6ts upp redan 2011. I b\u00f6rjan av innevarande \u00e5r intr\u00e4ffade ett fel ombord p\u00e5 «Spektr-R»: observatoriet slutade svara p\u00e5 kommandon. D\u00e4rmed har uppdraget f\u00f6r observatoriet, s\u00e5vitt det verkar, <\/a>avslutats<\/a><\/noindex>.<\/p>\n

Det \u00e4r v\u00e4rt att notera att det under sin tid samlade teleskopet «Spektr-R» en enorm m\u00e4ngd viktig vetenskaplig information. Just dessa data m\u00f6jliggjorde genomf\u00f6randet av projektet «Musik av pulsarer». «Nu kan alla f\u00e5 veta hur det l\u00e5ter i det kosmiska «orkestret» av 26 pulsarer, som de ryska forskarna studerade baserat p\u00e5 data fr\u00e5n det orbitala teleskopet «Spektr-R» och projektet «Radioastron», — p\u00e5pekar Roscosmos. <\/p>\n
