Axisymmetric ab initio core-collapse supernova simulations of 12-25 m ☉ stars

Abstract: We present an overview of four ab initio axisymmetric core-collapse supernova simulations employing detailed spectral neutrino transport computed with our CHIMERA code and initiated from Woosley and Heger progenitors of mass 12, 15, 20, and 25 M{sub Sun }. All four models exhibit shock revival over {approx}200 ms (leading to the possibility of explosion), driven by neutrino energy deposition. Hydrodynamic instabilities that impart substantial asymmetries to the shock aid these revivals, with convection appearing first in the 12 M{sub Sun} model and the standing accretion shock instability appearing first in the 25 M{sub Sun} model. Three of the models have developed pronounced prolate morphologies (the 20 M{sub Sun} model has remained approximately spherical). By 500 ms after bounce the mean shock radii in all four models exceed 3000 km and the diagnostic explosion energies are 0.33, 0.66, 0.65, and 0.70 Bethe (B = 10{sup 51} erg) for the 12, 15, 20, and 25 M{sub Sun} models, respectively, and are increasing. The three least massive of our models are already sufficiently energetic to completely unbind the envelopes of their progenitors (i.e., to explode), as evidenced by our best estimate of their explosion energies, which first become positive at 320, 380, andmore » 440 ms after bounce. By 850 ms the 12 M{sub Sun} diagnostic explosion energy has saturated at 0.38 B, and our estimate for the final kinetic energy of the ejecta is {approx}0.3 B, which is comparable to observations for lower mass progenitors.« less

Forgiveness or breakup: Sex differences in responses to a partner's infidelity

Abstract: Infidelities--sexual, emotional, or both--afflict many long-term romantic relationships. When a person discovers a partner's betrayal, a major decision faced is to forgive the partner and remain together or to terminate the relationship. Because men and women have confronted different adaptive problems over evolutionary history associated with different forms of infidelity, we hypothesised the existence of sex differences in which aspects of infidelity would affect the likelihood of forgiveness or breakup. We tested this hypothesis using forced-choice dilemmas in which participants (N = 256) indicated how difficult it would be to forgive the partner and how likely they would be to break up with the partner, depending on the nature of the infidelity. Results support the hypothesis that men, relative to women: (a) find it more difficult to forgive a sexual infidelity than an emotional infidelity; and (b) are more likely to terminate a current relationship following a partner's sexual infidelity than an emot...

The theory of planned behavior in entrepreneurship research: what we know and future directions

Abstract: The entrepreneurship literature utilizing the Theory of Planned Behavior (TPB) has grown considerably over the last 20 years. Therefore, it is time to take stock of the TPB’s contributions to our understanding of entrepreneurship thus far. In this paper, we review the relevant literature and present research suggestions that will guide scholars in the future. First, we organize the literature according to the part of the TPB utilized along four main themes found in the literature. We also outline the many additions and alterations that entrepreneurship scholars have implemented to the TPB. We then suggest future research based on the review. Taken together, our contributions highlight important contexts that have been understudied, and highlight important theoretical relationships that have received only a small amount of attention but have the potential for large future findings. Our contributions also speak to entrepreneurial behaviors and entrepreneurial intentions, the two main dependent variables of research that uses the TPB.
