Neutron Star Mergers Might Not Be the Only Source of r -process Elements in the Milky Way by Frebel, Anna L.

“…Steeper DTD functions (∝t -1.5) or power laws combined with a strong burst of mergers before the onset of supernovae (SNe) Ia can reproduce the [Eu/Fe] trend, but this scenario is inconsistent with the similar fraction of short GRBs and SNe Ia occurring in early-type galaxies, and it reduces the probability of detecting GW170817 in an early-type galaxy. One solution is to assume an additional production site of Eu that would be active in the early universe, but would fade away with increasing metallicity. …”

Constrain the time variation of the gravitational constant via the propagation of gravitational waves by Bing Sun, Jiachen An, Zhoujian Cao

“…In addition we can constrain the time variation of the gravitational constant via the propagation of gravitational waves based on GW170817 data. And more, we find that small variations in the gravitational constant result in an amplitude correction at the leading order and a phase correction at the sub-leading order for gravitational waves. …”

A Collapsar Origin for GRB 211211A Is (Just Barely) Possible by Jennifer Barnes, Brian D. Metzger

Kilonovae derive their unique electromagnetic signatures from the properties of the heavy elements synthesized by rapid neutron capture (the r -process) following the merger. …”

Realistic neutron star models in f(T) gravity by Rui-Hui Lin, Xiao-Ning Chen, Xiang-Hua Zhai

“…We obtain the mass–radius relations of the realistic models of neutron stars and subject them to the joint constraints from the observed massive pulsars PSR J0030+0451, PSR J0740+6620, and PSR J2215+5135, and gravitational wave events GW170817 and GW190814. For the neutron star model in f(T) gravity to be able to accommodate all the mentioned data, the model parameter $$\alpha $$ α needs to be smaller than $$-\,4.295$$ - 4.295 , $$-\,6.476$$ - 6.476 , $$-\,4.4$$ - 4.4 , and $$-\,2.12$$ - 2.12 (in the unit of $${G}^2M_\odot ^2/c^4$$ G 2 M ⊙ 2 / c 4 ) for SLy, BSk19, BSk20, and BSk21 equations of state, respectively. …”
