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.

Deciphering the bipolar planetary nebula Abell 14 with 3D ionization and morphological studies [PDF]
, 2016 Abell 14 is a poorly studied object despite being considered a born again planetary nebula. We performed a detailed study of its 3D morphology and ionization structure using the SHAPE and MOCASSIN codes.

Detecting Planets in Planetary Nebulae [PDF]
, 1998 We examine the possibility of detecting signatures of surviving Uranus-Neptune-like planets inside planetary nebulae. Planets that are not too close to the stars, orbital separation larger than about 5 AU, are likely to survive the entire evolution of ...

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.

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.

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 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.

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 ...

THE CHANDRA PLANETARY NEBULA SURVEY (ChanPlaNS). II. X-RAY EMISSION FROM COMPACT PLANETARY NEBULAE [PDF]
, 2014 We present results from the most recent set of observations obtained as part of the Chandra X-ray observatory Planetary Nebula Survey (ChanPlaNS), the first comprehensive X-ray survey of planetary nebulae (PNe) in the solar neighborhood (i.e., within ∼1 ...
