The Continued Hunt for the Neutron Star at the Heart of SN 1987A
I spy with my little eye a pulsar wind nebula at the heart of SN 1987A. Check out today’s bite to see the latest results in the search for SN 1987A’s compact object.
Minutes after Death, Reincarnation Can Begin
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.
Pre-Supernova Burps And Red Supergiant Reflux
Just before going supernova, some stars tend to have some gas problems, so why not simulate how?
Type II Supernovae are H0t on the Trail
Type Ia supernovae’s dimmer cousin, type II supernovae, take a shot at measuring the Hubble constant.
Going with the Tide: Does tidal dissipation play an important role in stellar/black hole mergers?
In today’s paper: how does tidal dissipation and gravitational wave emission affect the result of encounters between stars and black hole binaries in stellar clusters?
HEAVY, BUT NOT METAL: Could Metal-Free Stars be the Source of Massive Black Hole Mergers?
In today’s paper, the authors test the theory that the earliest, metal-poorest stars are the primary source of binary black hole mergers.
