Birth and early evolution of a planetary nebula [PDF]
, 1998 The final expulsion of gas by a star as it forms a planetary nebula --- the ionized shell of gas often observed surrounding a young white dwarf --- is one of the most poorly understood stages of stellar evolution.

SALT HRS discovery of a long-period double-degenerate binary in the planetary nebula NGC 1360 [PDF]
, 2017 Whether planetary nebulae (PNe) are predominantly the product of binary stellar evolution as some population synthesis models (PSM) suggest remains an open question.

SMC SMP 24: A Newly Radio-Detected Planetary Nebula in the Small Magellanic Cloud [PDF]
Serbian Astronomical Journal, 2010 In this paper we report a new radio-continuum detection of an extragalactic planetary nebula (PN): SMC~SMP~24. We show the radio-continuum image of this PN and present the measured radio data.

Complex molecules in the Orion Kleinmann-Low nebula
BIO Web of Conferences, 2014 In the framework of the delivery to the early Earth of extraterrestrial molecules, we have studied complex molecular species toward the Orion Kleinmann-Low nebula. This nebula is rich in molecules as well as in nascent stars and planetary systems.

Common Envelope Shaping of Planetary Nebulae. IV. From Proto-planetary to Planetary Nebula [PDF]
, 2022 We present 2D hydrodynamical simulations of the transition of a proto-planetary nebula to a planetary nebula for central stars in binary systems that have undergone a common envelope event. After 1,000 yr of magnetically driven dynamics (proto-planetary nebula phase), a line-driven stellar wind is introduced into the computational domain and the ...

Planetary nebula progenitors that swallow binary systems [PDF]
, 2015 I propose that some irregular `messy' planetary nebulae owe their morphologies to triple-stellar evolution where tight binary systems evolve inside and/or on the outskirts the envelope of asymptotic giant branch (AGB) stars.

Integral Field Spectroscopy of Planetary Nebulae with MUSE
Galaxies, 2020 The Multi-Unit Spectroscopic Explorer (MUSE) is a large integral field unit mounted on the ESO Very Large Telescope. Its spatial (60 arcsecond field) and wavelength (4800–9300Å) coverage is well suited to detailed imaging spectroscopy of extended ...

Planetary nebula or symbiotic Mira? Near infrared colours mark the difference [PDF]
Astron.Astrophys.377:L18,2001, 2001 Nebulae around symbiotic Miras look very much like genuine planetary nebulae, although they are formed in a slightly different way. We present near infrared photometry of known and suspected symbiotic nebulae obtained with the Deep Near Infrared Southern Sky Survey (DENIS).

HIGH-RESOLUTION IMAGING OF NGC 2346 WITH GSAOI/GeMS: DISENTANGLING THE PLANETARY NEBULA MOLECULAR STRUCTURE TO UNDERSTAND ITS ORIGIN AND EVOLUTION [PDF]
, 2015 We present high spatial resolution ( ≈ ?> 60–90 mas) images of the molecular hydrogen emission in the planetary nebula (PN) NGC 2346. The data were acquired during the system verification of the Gemini Multi-conjugate Adaptive Optics System + Gemini ...
