Why all these ‘neos’? Why now?
Ciencias Sociales y Religión, 2021 This article starts with a critique of the current mainstream approaches that share the implicit assumptions of what I call the “secularization paradigm”, showing how and why these approaches are ill-suited to understand the importance and constitution ...

Backscattering and Line Broadening in Orion
The Astronomical Journal, 2022 Examination of emission lines in high-velocity-resolution optical spectra of the Orion Nebula confirms that the velocity component on the red wing of the main ionization front emission line is due to backscattering in the Photon Dominated Region.

High velocity structures in, and the X-ray emission from the LBV nebula around Eta Carinae [PDF]
, 2000 The Luminous Blue Variable star Eta Carinae is one of the most massive stars known. It underwent a giant eruption in 1843 in which the Homunculus nebula was created. ROSAT and ASCA data indicate the existence of a hard and a soft X-ray component which appear to be spatially distinct: a softer diffuse shell of the nebula around Eta Carinae and a harder ...

Spatially Resolved Temperature and Density Structures of Nearby H ii Regions
The Astrophysical Journal, 2023 Photoionization models frequently assume constant temperature or density within H ii regions. We investigate this assumption by measuring the detailed temperature and density structures of four H ii regions in the Large Magellanic Cloud and the Small ...

Classification of ISO SWS 01 spectra of proto-planetary nebulae: a search for precursors of planetary nebulae with [WR] central stars [PDF]
arXiv, 2002 We have analyzed ISO SWS 01 observations for 61 proto-planetary nebulae candidates and classified their spectra according to their dominant chemistry. On the basis of our classification and the more general classification of SWS 01 spectra by Kraemer et al.

The Astrophysical JournalHD 148937 is a peculiar massive star (Of?p) with a strong magnetic field (1 kG). The hourglass-shaped emission nebula NGC 6164/5 surrounds this star. This nebula is presumed to originate from episodic mass-loss events of the central O-type star, but the ...
