Masses of the Planetary-Nebula Central Stars in the Galactic Globular-Cluster System from HST Imaging and Spectroscopy
George H. Jacoby, Orsola De Marco, James Davies +4
The globular cluster (GC) system of our Galaxy contains four planetary nebulae (PNe): K 648 (or Ps 1) in M15, IRAS 18333-2357 in M22, JaFu 1 in Pal 6, and JaFu 2 in NGC 6441. Becau…
Post-common envelope PN, fundamental or irrelevant?
Orsola De Marco, T. Reichardt, R. Iaconi +6
One in 5 planetary nebulae are ejected from common envelope binary interactions but Kepler Space Telescope results are already showing this proportion to be larger. Their propertie…
Planetary nebulae : getting closer to an unbiased binary fraction
D. Douchin, O. De Marco, G. H. Jacoby +5
Why 80% of planetary nebulae are not spherical is not yet understood. The Binary Hypothesis states that a companion to the progenitor of the central star of a planetary nebula is r…
Searching for binary central stars of planetary nebulae with Kepler
D. Douchin, G. H. Jacoby, O. De Marco +2
The Kepler Observatory offers unprecedented photometric precision (<1 mmag) and cadence for monitoring the central stars of planetary nebulae, allowing the detection of tiny period…
