Prof. Willy Kley, a pioneer in the field of protoplanetary disks, unexpectedly died in December 2021. Today’s post commemorates Willy’s legacy and summarizes a scientific conference that was held in memory of Willy in the beginning of August.
The authors of today’s paper simulate in impeccable detail the first few minutes of a binary-driven hypernova (the brighter cousin of a supernova) while paying close attention to how the dynamics affect the companion neutron star. They predict several observables from the process, including what has been observed in the gamma ray burst event GRB 190829A.
Three Astrobiters review Dr. Moiya McTier’s new book, The Milky Way, published today!
Satellite constellations are changing ground-based astronomy with every new launch. How can we quantify their impacts, and can anything be done to mitigate them?
Just before going supernova, some stars tend to have some gas problems, so why not simulate how?
