The evolving spectrum of the planetary nebula Hen 2-260 [PDF]
, 2014 We analysed the planetary nebula Hen 2-260 using optical spectroscopy and photometry. We compared our observations with the data from literature to search for evolutionary changes.

The <i>Herschel</i> Planetary Nebula Survey (HerPlaNS): A Comprehensive Dusty Photoionization Model of NGC6781. [PDF]
Astrophys J Suppl Ser, 2017 We perform a comprehensive analysis of the planetary nebula (PN) NGC 6781 to investigate the physical conditions of each of its ionized, atomic, and molecular gas and dust components and the object’s evolution, based on panchromatic observational data ...

Observations of the planetary nebula SMP LMC 058 with the JWST MIRI medium resolution spectrometer [PDF]
Monthly notices of the Royal Astronomical Society, 2023 During the commissioning of JWST, the Medium-Resolution Spectrometer (MRS) on the Mid-Infrared Instrument (MIRI) observed the planetary nebula SMP LMC 058 in the Large Magellanic Cloud.

The messy death of a multiple star system and the resulting planetary nebula as observed by JWST [PDF]
Nature Astronomy, 2022 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.

The mysterious cut-off of the Planetary Nebula Luminosity Function [PDF]
, 2018 Planetary Nebulae (PNe) mark the end of the active life of 90% of all stars. They trace the transition from a red giant to a degenerate white dwarf. Stellar models predicted that only stars above approximately twice the solar mass could form a bright PN.

The MUSE view of the planetary nebula NGC 3132 [PDF]
Astronomy & Astrophysics, 2019 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 spaxel-by-spaxel basis for the many emission lines falling within the Multi-Unit ...

ALMA imaging of the nascent planetary nebula IRAS 15103–5754 [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We present continuum and molecular-line (CO, C18O, HCO+) observations carried out with the Atacama Large Millimeter/submillimeter Array toward the ‘water fountain’ star IRAS 15103–5754, an object that could be the youngest planetary nebula (PN) known ...

Planetary nebula distances in Gaia DR2 [PDF]
Astronomy & Astrophysics, 2018 Context. Planetary nebula distance scales often suffer from model-dependent solutions. Model-independent trigonometric parallaxes have been rare. Space-based trigonometric parallaxes are now available for a larger sample using the second Data Release of ...

A high-mass planetary nebula in a Galactic open cluster [PDF]
Nature Astronomy, 2019 Planetary nebulae are the ionized ejected envelopes surrounding the remnant cores of dying stars. Theory predicts that main-sequence stars of one to about eight solar masses may eventually form planetary nebulae. Until now, this has not been confirmed at

The short orbital period binary star at the heart of the planetary nebula M 3-1★ [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2018 We present the discovery of a 3h5m orbital-period binary star at the heart of the planetary nebula M 3-1 - the shortest period photometrically-variable central star known and second only to V458 Vul, in general.
