Dissecting NGC 3132: Tracing the mass-loss history of the southern ring planetary nebula

K. Bouvis, S. Akras, H. Monteiro +7

Central to our understanding of stellar evolution and its impact on processes in our Galaxy and across the Universe is the study of mass loss. While the general framework is well e…

Nickel- and iron-rich clumps in planetary nebulae: New discoveries and emission-line diagnostics

K. Bouvis, S. Akras, H. Monteiro +7

Integral field spectroscopy (IFS) offers a distinct advantage for studying extended sources by enabling spatially resolved emission maps for several emission lines without the need…

Integral field spectroscopy of the planetary nebula NGC 3242 and the puzzling nature of its low ionization structures

L. Konstantinou, S. Akras, J. Garcia-Rojas +7

The physico-chemical properties of the planetary nebula (PN) NGC 3242 are investigated in both 1D and 2D, using Integral Field Unit (IFU) data. This PN has a complex morphology wit…

Detection of the [C I] 8727 emission line. Low-ionization structures in NGC 7009

Stavros Akras, Hektor Monteiro, Jeremy R. Walsh +5

We report the first spatially resolved detection of the near-infrared [C I] 8727 emission from the outer pair of low-ionization structures in the planetary nebula NGC 7009 from…

Initial periods and magnetic fields of neutron stars

Andrei P. Igoshev, Anastasia Frantsuzova, Konstantinos N. Gourgouliatos +3

Initial distributions of pulsar periods and magnetic fields are essential components of multiple modern astrophysical models. Not enough work has been done to properly constrain th…
