Dust To Dust: The End of Astronomy
The proliferation of space debris is viably the end of space- and ground- based astronomy. Action is required now, before the number of satellites increases hundred-fold.
Hypervelocity Stars, TŻOs, Bumpy Superluminous Supernovae, and Pulsar Planets May All Share An Origin
The collision –or even a near-miss– of a neutron star and a main sequence star can possibly explain long-lived, bumpy supernovae and hypervelocity stars.
A Machine Learning View of Supernova GWs
How does one measure the gravitational wave signal of a supernova if each event is unique? Is machine learning up to the task? Or is it unknowable?
How To Take Down A Satellite
Bright satellites have dire effects on the field of astronomy, indigenous religious practices life cycles, and our quality of living. Blue Walker 3 can outshine Venus in the night sky. AST plans to have 110 of these satellites by 2024.
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.
