Lunar Secondary Craters and Estimated Ejecta Block Sizes Reveal a Scale‐Dependent Fragmentation Trend [PDF]
Journal of Geophysical Research: Planets, 2020 Planetary impact events eject large volumes of surface material. Crater excavation processes are difficult to study, and in particular the details of individual ejecta fragments are not well understood.

A Low-mass Binary Neutron Star: Long-term Ejecta Evolution and Kilonovae with Weak Blue Emission [PDF]
Astrophysical Journal, 2020 We study the long-term evolution of ejecta formed in a binary neutron star (NS) merger that results in a long-lived remnant NS by performing a hydrodynamics simulation with the outflow data of a numerical relativity simulation as the initial condition ...

Size distribution of virus laden droplets from expiratory ejecta of infected subjects
Scientific Reports, 2020 For rebooting economic activities in the ongoing COVID-19 pandemic scenario, it is important to pay detailed attention to infection transfer mechanisms during interaction of people in enclosed environments.

Production of Very Light Elements and Strontium in the Early Ejecta of Neutron Star Mergers [PDF]
Astrophysical Journal, 2020 We study the production of very light elements (Z < 20) in the dynamical and spiral-wave wind ejecta of binary neutron star mergers by combining detailed nucleosynthesis calculations with the outcome of numerical relativity merger simulations.

Kilonova from post-merger ejecta as an optical and near-infrared counterpart of GW170817 [PDF]
, 2017 Recent detection of gravitational waves from a neutron star (NS) merger event GW170817 and identification of an electromagnetic counterpart provide a unique opportunity to study the physical processes in NS mergers.

High Angular Resolution ALMA Images of Dust and Molecules in the SN 1987A Ejecta [PDF]
Astrophysical Journal, 2019 We present high angular resolution (∼80 mas) ALMA continuum images of the SN 1987A system, together with CO J = 2 1, J = 6 5, and SiO J = 5 4 to J = 7 6 images, which clearly resolve the ejecta (dust continuum and molecules) and ring (synchrotron ...

A Magnetar Origin for the Kilonova Ejecta in GW170817 [PDF]
, 2018 The neutron star (NS) merger GW170817 was followed over several days by optical-wavelength (“blue”) kilonova (KN) emission likely powered by the radioactive decay of light r-process nuclei synthesized by ejecta with a low neutron abundance (electron ...
