Inside Pulsating White Dwarfs: Clues from time-resolved spectroscopy
Popular Abstract in Swedish Pulserande stjärnrester (OBS! Kontakta mig för figurerna eller se artikeln publicerat i Populär Astronomi). Rubina Kotak, Populär Astronomi, 2002, Nr 2, sid. 29 Stjärnorna's utveckling: Solen är idag ungefär fem miljarder, alltså fem tusen miljoner år gammal. Hur ser solen's framtiden ut? Som i de allra flesta stjärnor, pågår även i solen's innersta delar kärn reaktiSeveral analyses using time-resolved optical spectrocopy of pulsating white dwarfs are presented. The data have been put to a number of uses. First, line-of-sight velocities associated with the pulsations have been measured in three hydrogen-atmosphere white dwarfs (DAVs), bringing the total number of such measurements up to five. They have also been measured for the first time in a pulsating heli
