Title: The Impact of Nuclear Reaction Rate Uncertainties on the Evolution of Core-collapse Supernova Progenitors

Abstract

We review properties of core-collapse supernova progenitors with respect to the composite uncertainties in the thermonuclear reaction rates by coupling the probability density functions of the reaction rates provided by the STARLIB reaction rate library with MESA stellar models. We evolve 1000 models of 15$${M}_{\odot }$$ from the pre-main sequence to core O-depletion at solar and subsolar metallicities for a total of 2000 Monte Carlo stellar models. For each stellar model, we independently and simultaneously sample 665 thermonuclear reaction rates and use them in a MESA in situ reaction network that follows 127 isotopes from ¹H to ⁶⁴Zn. With this framework we survey the core mass, burning lifetime, composition, and structural properties at five different evolutionary epochs. At each epoch we measure the probability distribution function of the variations of each property and calculate Spearman rank-order correlation coefficients for each sampled reaction rate to identify which reaction rate has the largest impact on the variations on each property. We find that uncertainties in the reaction rates of $${}^{14}{\rm{N}}{({\rm{p}},\gamma )}^{15}{\rm{O}}$$, triple-α, $${}^{12}{\rm{C}}{(\alpha ,\gamma )}^{16}{\rm{O}}$$, ¹²C(¹²C,p)²³Na, ¹²C(¹⁶O, p)²⁷Al, ¹⁶O(¹⁶O,n)³¹S, ¹⁶O(¹⁶O, p)³¹P, and ¹⁶O(¹⁶O,α)²⁸Si dominate the variations of the properties surveyed. We find that variations induced by uncertainties in nuclear reaction rates grow with each passing phase of evolution, and at core H-, He-depletion they are of comparable magnitude to the variations induced by choices of mass resolution and network resolution. Yet, at core C-, Ne-, and O-depletion, the reaction rate uncertainties can dominate the variation, causing uncertainty in various properties of the stellar model in the evolution toward iron core-collapse.

THE EFFECTS OF THERMONUCLEAR REACTION RATE VARIATIONS ON {sup 26}Al PRODUCTION IN MASSIVE STARS: A SENSITIVITY STUDY

Journal Article Iliadis, Christian ; Champagne, Art ; Chieffi, Alessandro ; ... - Astrophysical Journal, Supplement Series

We investigate the effects of thermonuclear reaction rate variations on {sup 26}Al production in massive stars. The dominant production sites in such events were recently investigated by using stellar model calculations: explosive neon-carbon burning, convective shell carbon burning, and convective core hydrogen burning. Post-processing nucleosynthesis calculations are performed for each of these sites by adopting temperature-density-time profiles from recent stellar evolution models. For each profile, we individually multiplied the rates of all relevant reactions by factors of 10, 2, 0.5, and 0.1, and analyzed the resulting abundance changes of {sup 26}Al. In total, we performed {approx}900 nuclear reaction network calculations.more »« less

Journal Article Tur, Clarisse ; Austin, Sam M ; Heger, Alexander - Astrophysical Journal

We have studied the sensitivity to variations in the triple alpha and {sup 12}C({alpha}, {gamma}){sup 16}O reaction rates of the production of {sup 26}Al, {sup 44}Ti, and {sup 60}Fe in core-collapse supernovae (SNe). We used the KEPLER code to model the evolution of 15 M {sub sun}, 20 M {sub sun}, and 25 M {sub sun} stars to the onset of core collapse and simulated the ensuing SN explosion using a piston model for the explosion and an explosion energy of 1.2 x 10{sup 51} erg.

Reaction Rate Sensitivity of the Production of γ-Ray Emitting Isotopes in Core-collapse Supernovae

Journal Article Hermansen, Kirby ; Couch, Sean M. ; Roberts, Luke F. ; ... - The Astrophysical Journal

Radioactive isotopes produced in core-collapse supernovae (CCSNe) provide useful insights into the underlying processes driving the collapse mechanism and the origins of elemental abundances. Their study generates a confluence of major physics research, including experimental measurements of nuclear reaction rates, astrophysical modeling, and γ-ray observations. Here we identify the key nuclear reaction rates to the nucleosynthesis of observable radioactive isotopes in explosive silicon burning during CCSNe. Using the nuclear reaction network calculator SkyNet and current REACLIB reaction rates, we evolve temperature–density–time profiles of the innermost 0.45 M⊙ ejecta from the core collapse and explosion of a 12 M⊙ star.
