A hydrodynamical study of multiple-shell planetary nebulae. III. Expansion properties and internal kinematics: Theory versus observation
D. Schoenberner, R. Jacob, H. Lehmann +5
We present the result of a study on the expansion properties and internal kinematics of round/elliptical planetary nebulae of the Milky Way disk, the halo, and of the globular clus…
New observations of the halo radial temperature structure in NGC7662
C. Sandin, D. Schoenberner, M. M. Roth +4
We report on our studies of the physical structure of the planetary nebula (PN) NGC7662. Using (3D) Integral Field Spectroscopy we have been able to measure the electron temperatur…
Stellar archaeology: the evolving spectrum of FG Sge
C. S. Jeffery, D. Schoenberner
Over an interval of 120 years, the extraordinary object FG Sge has been transformed from a hot post-AGB star to a very luminous cool supergiant. Theoretically, this evolution has b…
The evolution of helium white dwarfs: III. On the ages of millisecond pulsar systems
D. Schoenberner, T. Driebe, T. Bloecker
We employed recently computed evolutionary white-dwarf models with helium cores, supplemented by heavier models with carbon-oxygen cores, in order to investigate the ages of millis…
On the Transition from AGB Stars to Planetaries: The Spherical Case
Detlef Schoenberner, Matthias Steffen
We discuss the basic physical model and the relevant processes responsible for creating and shaping planetary nebulae out of a cool AGB wind envelope. We show that a hydrodynamical…
Evolutionary Models of White Dwarfs with Helium Cores
T. Driebe, D. Schoenberner, T. Bloecker +1
We present seven evolutionary tracks for low-mass white dwarfs with helium cores, ranging in mass from 0.179 to 0.414 Msol. We generated the pre-white dwarf models from a 1 Msol se…
