Thanks to astronomical surveys, we now know our night sky is constantly alight with variable objects. Tune in to Prof. Christopher Kochanek’s Dannie Heineman Prize talk at #AAS237 to learn about how small telescopes can change the way we observe our rapidly changing universe!
Massive stars live fast and die young, making metals along the way.
All stars die, but not all stars die the same. Some will explode and leave no trace behind. These special explosions with no trace are called pair-instability supernovae (PISNe) and only happen in the most massive of stars. Today’s paper from 2009 investigates a unique supernova, SN 2007bi, that was initially thought to be the first PISN ever observed.
Aluminum can be used for so much more than foil. What can it tell us about our solar system’s place in the galaxy? Read about today’s paper to find out more.
Accounting for the uncertainty in supernova explosion parameters can substantially change the star formation history and morphology of galaxy simulations.
ASAS-SN searches for supernova and finds variable stars too! They found so many (~90,000) that they decided to classify them all. How do you go about classifying 90,000 things? Machine learning, of course!
