Evidence for neutron capture in heavy-metal hot subdwarfs: Far-UV spectroscopy of EC22536-5304 and LSIV-14 116
M. Dorsch, C. S. Jeffery, J. Deprince +8
Most hot subdwarfs (sdO/B) are low-mass core-helium-burning stars formed through binary interaction. A subgroup of intermediate He-rich sdOBs shows extreme heavy-metal (Z>30) enric…
Benchmarking the Plane-Wave Born and Distorted Waves approximations for electron-impact collision strength computations: the sample case of Sr II
Jérôme Deprince, Lucas Maison
The discovery of gravitational waves from a neutron star merger in 2017 (GW170817) and the associated kilonova (AT2017gfo) confirmed these events as key sites for heavy element pro…
Kilonova ejecta opacity inferred from new large-scale HFR atomic calculations in all elements between Ca (Z = 20) and Lr (Z = 103)
Jérôme Deprince, Gururaj Wagle, Sirine Ben Nasr +7
In the context of kilonova (KN) modeling, the present work focusses on large-scale atomic data and opacity computations for all heavy elements from Ca to Lr, with a special effort…
Opacities of Singly and Doubly Ionised Neodymium and Uranium for Kilonova Emission Modeling
A. Flörs, R. F. Silva, J. Deprince +10
Even though the electromagnetic counterpart AT2017gfo to the binary neutron star merger GW170817 is powered by the radioactive decay of r-process nuclei, only few tentative identif…
Detection of cesium in the atmosphere of the hot He-rich white dwarf HD 149499B
P. Chayer, C. Mendoza, M. Meléndez +2
We report the first detection of cesium (Z = 55) in the atmosphere of a white dwarf. Around a dozen absorption lines of Cs IV, Cs V, and Cs VI have been identified in the Far Ultra…
Plasma environment effects on K lines of astrophysical interest. V. Universal formulae for ionization potential and K-threshold shifts
P. Palmeri, J. Deprince, M. A. Bautista +5
Aims. We calculate the plasma environment effects on the ionization potentials (IPs) and K-thresholds used in the modeling of K lines for all the ions belonging to the isonuclear s…
Photoionization Models for High Density Gas
T. Kallman, M. Bautista, J. Deprince +5
Relativistically broadened and redshifted 6.4 -- 6.9 keV iron K lines are observed from many accretion powered objects, including X-ray binaries and active galactic nuclei (AGN). E…
Plasma-environment effects on K lines of astrophysical interest III. IPs, K thresholds, radiative rates, and Auger widths in Fe ix - Fe xvi
J. Deprince, M. A. Bautista, S. Fritzsche +5
Aims. In the context of black-hole accretion disks, we aim to compute the plasma-environment effects on the atomic parameters used to model the decay of K-vacancy states in moderat…
Plasma environment effects on K lines of astrophysical interest. II. Ionization potentials, K thresholds, radiative rates and Auger widths in Ne- through He-like iron ions (Fe xvii - Fe xxv)
J. Deprince, M. A. Bautista, S. Fritzsche +5
Aims. In the context of accretion disks around black holes, we estimate plasma-environment effects on the atomic parameters associated with the decay of K-vacancy states in highly…
Plasma environment effects on K lines of astrophysical interest I. Atomic structure, radiative rates and Auger widths of oxygen ions
Deprince J., Bautista M. A., Fritzsche S. +5
Aims. In the context of black-hole accretion disks, the main goal of the present study is to estimate the plasma environment effects on the atomic structure and radiative parameter…
Plasma Effects On Atomic Data For The K-Vacancy States Of Highly Charged Iron Ions
Jérôme Deprince, Stefan Fritzsche, Tim Kallman +2
The main goal of the present work is to estimate the effects of plasma environment on the atomic parameters associated with the K-vacancy states in highly charged iron ions within…
