  • Collapsar model can match some kilonova-like bursts

    —

    in

    What the study found The authors report that recent kilonova-like emission after long-duration gamma-ray bursts, including GRB 211211A and GRB 230307A, can be explained by a collapsar scenario rather than only by a merger of two neutron stars. Why the authors say this matters The study suggests that a red evolution in these transients does…

  • BAGLE adds binary lens and source models for microlensing

    —

    in

    What the study found The BAGLE Python software package now includes models for binary sources and binary lenses in gravitational microlensing. These models include Keplerian orbits, as well as simpler descriptions of orbital motion such as acceleration, linear, or stationary motion of the secondary companion. Why the authors say this matters The authors say these…
