How Do Planetary Nebulae Influence the Evolution of Type Ia Supernovae?
Planetary nebulae where they shouldn’t be–how did they get there?
On 16th November in 483 CE, astronomers in China recorded the appearance of “a guest star east of Shen, as large as a peck measure, and like a fuzzy star”. The new celestial light shone brightly for just under a month, then faded to nothing. Over 1500 years later, the authors of today’s paper suggests that they may have found the source.
Sometimes, stellar evolution happens on more human timescales—tens to hundreds of years rather than millions or billions.
How can a star heat up by 40,000 K in just 30 years? Reindl et al. explore the star at the heart of the Stingray Nebula to find out.
