Video of a simulation aligned with an AAVSO light curve of chi Cygni
At the URL below is a video of the 2002-2008 AAVSO light curve of chi Cygni sync'd with a simulation of the expansion and contraction of the star.
However, before you watch it, ask yourself these questions:
- What are the common ways intrinsic variable stars like this one change in brightness? How does that differ from a star like epsilon Aurigae?
- As the star gains brightness in the light curve, what do you expect to happen in the simulation?
The watch the video:
The video shows some things that, at first glance, may be unexpected. What surprises you about the video?
Serious kudos to Sylvestre Lacour, Observatoire de Paris. This is cool stuff.
