What happens when a planet's sun loses mass?

The Great Escape: How Exoplanets and Smaller Bodies Desert Dying Stars

In the intermediate case where the timescale of the mass loss is comparable to the orbital period, the orbital eccentricity can be increased >1, ejecting the planet.

Very interesting article, and partly for the comment section:

PSR B1257+12 systems are moderately rare - about 1% of millisecond pulsars seem to have low mass planets.
For regular pulsars the fraction is more like 0.1%.

People are indeed looking for them, quite hard...

Watch this space!
Soon...
