Could Rings Explain an Intriguing Exoplanet Spectrum?
Interpreting observations of an exoplanet’s atmosphere can be tricky, but in today’s astrobite, planetary rings could be the missing piece of the puzzle
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.
Did a Cannonball create Sgr A East?
How was the closest supernova remnant to the galactic core created? Sgr A East is young, mysterious and could even tells the story of its origin. Perhaps we’ve already observed the stellar corpse left behind by the explosion which created the remnant.
The Case of the Evaporating Exoplanet
Today’s authors investigate a young star hosting an exoplanet, and watch as its X-ray flares speed up the planet’s evaporation!
