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 ...

Decisions Under Radical Uncertainty: The Role of Volitional Liminality in Radical Innovation

Journal of Product Innovation Management, EarlyView.
ABSTRACT Academic Summary Radical innovation management can be understood as an organizational practice that enacts distant futures, which are open‐ended and unknowable. Such radical innovation endeavors are thus characterized by radical uncertainty, where possible futures are not only quantitatively but qualitatively different from the present, and ...

First release of the IPHAS catalogue of new extended planetary nebulae [PDF]

, 2014
We present the first results of our search for new, extended planetary nebulae (PNe) based on careful, systematic, visual scrutiny of the imaging data from the Isaac Newton Telescope Photometric Hα Survey of the Northern Galactic plane (IPHAS). The newly

Noble gases and nitrogen in material from asteroid Bennu

Meteoritics &Planetary Science, EarlyView.
Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

THE CHANDRA PLANETARY NEBULA SURVEY (ChanPlaNS). III. X-RAY EMISSION FROM THE CENTRAL STARS OF PLANETARY NEBULAE [PDF]

, 2014
We present X-ray spectral analysis of 20 point-like X-ray sources detected in Chandra Planetary Nebula Survey observations of 59 planetary nebulae (PNe) in the solar neighborhood.

Aggregation and the Structure of Value

Noûs, EarlyView.
ABSTRACT Roughly, the view I call “Additivism” sums up value across time and people. Given some standard assumptions, I show that Additivism follows from two principles. The first says that how lives align in time cannot, in itself, matter. The second says, roughly, that a world cannot be better unless it is better within some period or another.

SATELLITE: Application to Planetary Nebulae IFU Data

Galaxies, 2022
The integral field unit (IFU) spectroscopic view of extended ionized nebulae, such as planetary nebulae (PNe), H II regions, and galaxies, has changed the approach of studying these objects, providing a simultaneous characterization in both spatial ...

Jungian categories as modes of reading: The case of Graham Greene's The Heart of the Matter and Aldous Huxley's Time Must Have a Stop

Orbis Litterarum, EarlyView.
Abstract This essay advocates renewed attention toward Jungian literary criticism, emphasizing its unique and creative perspectives on both fictional worlds and on reading. A fresh turn to Jungian criticism offers, in particular, valuable insight for texts on the peripheries of the canon.
