There are other sources of ejected material, such as winds from the accretion disk which forms around the remnant (whether black hole or neutron star) following the collision, so this is only part of the picture; however, we can estimate the mass of the dynamical ejecta from our ...
The gravitational-wave GW170817 is compatible with a binary neutron star (BNS) inspiral of chirp mass1.186(1)M_{\odot }[1,2,3]. Significant signal-to-noise ratio (SNR) is found in the frequency range 30–600 Hz, roughly corresponding to the last thousand orbits to merger for an equal-...
10 9 k. the real composition of neutron star crusts can also differ from the ground state due to the fallback of material from the envelope ejected during the supernova explosion and due to the accretion of matter. in particular, an accreted crust is a site of x-ray bursts. the ashes ...
In a famous sequence in the original Star Wars movie, Obe Wan Kenobie, using a Jedi mind trick, fools imperial foot soldiers searching the city into believing that “these are not the droids we are looking for.” China’s release of Deep Seek has executed the equivalent of a Jedi mind ...
I highly recommend Neutron Stars to anyone who wants to learn not only about the history of neutron star research, but also the current race to understand fast radio bursts, magnetars, and colliding neutron stars.-- Stephen R. Taylor, Vanderbilt University With journalistic flair, unlimited ...

With all that starlight removed, the researchers were left with unprecedented, extremely detailed pictures of the shape and evolution of the afterglow over time.The picture that emerged doesn't look like anything we'd see if we looked up into the night sky with just our eyes, Fong told ...
LIGO, has detected mergers of black holes, and even a couple of neutron star smash-ups. Now it may have picked up the signature of a black hole gobbling a neutron star.
In 2017, gravitational waves were detected following a neutron-star merger. The light curve of its kilonova remnant was firmly linked to the r-process, providing further impetus to the study of the heavy neutron-rich region [3]. The progress achieved in the study of the region is illustrated...
because the e.m. couplingeas well as the difference betweenm_uandm_dare small. The weak interaction provides the neutron mass with an imaginary part and generates a shift of the real part as well, but these effects are tiny and will be neglected. The Standard Model then reduces to QED +...
