Watching PrePNe Evolve: 15 Years of HST Observations
Multi-epoch HST images have been obtained for the pre planetary nebulae CRL618, CRL2688, and Hen3-1475. Each object shows clear and idiosyncratic expansion...
WEAVE imaging spectroscopy of NGC 6720: an iron bar in the Ring
We present spatially resolved spectroscopic observations of the planetary nebula NGC 6720, the Ring Nebula, taken during the science verification phase of WEAVE...

When nature tries to trick us. An eclipsing eccentric close binary superposed on the central star of the planetary nebula M 3-2
Bipolar planetary nebulae (PNe) are thought to result from binary star interactions and, indeed, tens of binary central stars of PNe have been found, in...
Context. The Gaia Data Release 2 (DR2) was used to select a sample of 211 central stars of planetary nebulae (CSPNe) with good-quality astrometric measurements...
A large fraction of all stars, after experiencing heavy winds at the end of the Asymptotic Giant Branch (AGB) phase, leave behind a core that is below the...
During the late stages of their evolution, Sun-like stars bring the products of nuclear burning to the surface. Most of the carbon in the Universe is believed...
[WC] Stellar Wind Turbulent Outflows Feeding the ISM
Wind fluctuations in [WC 8-9]-type central stars of planetary nebulae have been detected. Moving features seen on the top of the C III lambda 5696 and C IV...
