Presentation Transcript

  1. Razvoj zvezd

  2. Življenje zvezd • Nastanek iz medzvezdnega plina z m> MJeans • Numerična simulacija (http://www.ukaff.ac.uk/starcluster/)

  3. razvoj zvezd boj gravitacije proti tlaku: zlivanje atomskih jeder

  4. Planetarna meglica C,O

  5. Goriva zmanjka, zvezda se krči (nevtronsko zvezdo ali črno luknjo) gravitacijska energija • Eksplozija supernove: core collapse Sn ali Tip II, Tip Ib, Ic, izbruhi žarkov gama)

  6. SN 1604 Keplerjeva SN

  7. meglica Rakovica SN 1054

  8. SN Tip Ia

  9. sunki na sekundo čas v sekundah Vir: NASA

  10. optični “afterglow” Vir: NASA, Vesoljski teleskop Hubble

  11. kolaps zvezde

  12. zlitje nevtronskih zvezd

  13. ...in konec zgornja meja za maso: - bele pritlikavke: Chandrasekharjeva limita =1.4 MS - nevtronske zvezde: 2-10 MS

  14. Velikosti in gostote premer gostota Sonce 1.400.000 km 1,4 kg/dm3 bela pritlikavka 15.000 km 1000 ton/dm3 nevtronska zvezda 20 km 1015 kg/dm3 !!! črna luknja 15 km ?

  15. Vela

  16. Kako opaziti črne luknje?

  17. dvojni zvezdni sistemi periodični Dopplerjev premik spektralnih črt rentgentske dvojnice: ena zvezda nevidna, rentgentski izvor: *

  18. stava – Labod X1
