Deep Learning application for stellar parameters determination: II- Application to observed spectra of AFGK stars
Marwan Gebran, Frédéric Paletou, Ian Bentley +2
In this follow-up paper, we investigate the use of Convolutional Neural Network for deriving stellar parameters from observed spectra. Using hyperparameters determined previously,…
Deep Learning application for stellar parameters determination: I- Constraining the hyperparameters
Marwan Gebran, Kathleen Connick, Hikmat Farhat +2
Machine Learning is an efficient method for analyzing and interpreting the increasing amount of astronomical data that is available. In this study, we show, a pedagogical approach…
Role of pair-vibrational correlations in forming the odd-even mass difference
K. Neergård, I. Bentley
In the random-phase-approximation-amended (RPA-amended) Nilsson-Strutinskij method of calculating nuclear binding energies, the conventional shell correction terms derived from the…
Comment on "No-core configuration-interaction model for the isospin- and angular-momentum-projected states" by Satuła, Baczyk, Dobaczewski, and Konieczka
I. Bentley, K. Neergård, S. Frauendorf
The authors state that results recently published by Carlsson and Toivanen "seem to contradict" the conclusions of some of our work. We show that this statement is based on a misin…
Shell structure from nuclear observables
I. Bentley, Y. Colon Rodrıguez, S. Cunningham +1
The appearance and disappearance of shells and subshells are determined using a previously introduced method of structural analysis. This work extends the approach and applies it t…
Particle-hole symmetry parameters for nuclei
Ian Bentley
Two new numbers, and , inspired by particle-hole symmetry are introduced. These numbers have extreme values at a closed shell and vanish mid-shell. A combination of even pow…
Nuclear masses near N = Z from Nilsson-Strutinsky calculations with pairing corrections beyond BCS from an isospin-conserving pairing force
I. Bentley, K. Neergård, S. Frauendorf
A model with nucleons in a charge-independent potential well interacting by an isovector pairing force is considered. For a 24-dimensional valence space, the Hartree-Bogolyubov (HB…
Sensitivity studies for r-process nucleosynthesis in three astrophysical scenarios
R. Surman, M. Mumpower, J. Cass +3
In rapid neutron capture, or r-process, nucleosynthesis, heavy elements are built up via a sequence of neutron captures and beta decays that involves thousands of nuclei far from s…
Sensitivity of the r-process to nuclear masses
S. Brett, I. Bentley, N. Paul +2
The rapid neutron capture process (r-process) is thought to be responsible for the creation of more than half of all elements beyond iron. The scientific challenges to understandin…
Relation between Wigner energy and proton-neutron pairing
I. Bentley, S. Frauendorf
The linear term proportional to in the nuclear symmetry energy (Wigner energy)is obtained in a model that uses isovector pairing on single particle levels from a deformed p…
Microscopic Calculation of IBM Parameters by Potential Energy Surface Mapping
I. Bentley, S. Frauendorf
A coherent state technique is used to generate an Interacting Boson Model (IBM) Hamiltonian energy surface that simulates a mean field energy surface. The method presented here has…
High Magnetic Shear Gain in a Liquid Sodium Stable Couette Flow Experiment; A Prelude to an alpha-Omega Dynamo
Stirling A. Colgate, Hui Li, Vladimir Pariev +15
The -phase of the liquid sodium - dynamo experiment at NMIMT in cooperation with LANL has successfully demonstrated the production of a high toroidal field, $B_ϕ \simeq 8\…
Instantaneous Shape Sampling - a model for the -absorption cross section of transitional nuclei
I. Bentley, S. Brant, F. Doenau +4
The influence of the quadrupole shape fluctuations on the dipole vibrations in transitional nuclei is investigated in the framework of the Instantaneous Shape Sampling Model, which…
