Abstract The James Webb Space Telescope (JWST) Early Release Observations (EROs) is
a set of public outreach products created to mark the end of commissioning and the …

Measuring the distances to Galactic planetary nebulae (PNe) has been an intractable
problem for many decades. We have now established a robust optical statistical distance …

Planetary nebulae—the ejected envelopes of red giant stars—provide us with a history of
the last, mass-losing phases of 90% of stars initially more massive than the Sun. Here we …

The study of photoionized environments is fundamental to many astrophysical problems. Up
to the present most photoionization codes have numerically solved the equations of …

Aims. Two-dimensional spectroscopic data for the whole extent of the NGC 3132 planetary
nebula have been obtained. We deliver a reduced data-cube and high-quality maps on a …

Athough planetary nebulae (PNe) have been discovered for over 200 years, it was not until
30 years ago that we arrived at a basic understanding of their origin and evolution. Even …

We present the initial results from the Infrared Array Camera (IRAC) imaging survey of
planetary nebulae (PNs). The IRAC colors of PNs are red, especially in the 8.0 μm band …

The planetary nebula (PN) NGC 3132 is a striking example of the dramatic but poorly
understood mass-loss phenomena that (1–8) M⊙ stars undergo during their death throes as …

Since various structural components of planetary nebulae (PN) manifest themselves
differently, a combination of optical, infrared, submillimetre and radio techniques is needed …

Abstract The three-dimensional Monte Carlo photoionization code mocassin has been
applied to construct a realistic model of the planetary nebula NGC 3918. Three different …
