WDJ0914+1914

Dec. 7, 2019

A study published in the journal Nature has for the first time provided evidence of a planet surviving a white dwarf event.

About:

Some 4.5 billion years from today, our Sun will run of fuel and shed its outer layers. What will remain of the Sun is called a “white dwarf”.
In the process, it will destroy Mercury, Venus and probably Earth, and is expected to radiate enough high energy photons to evaporate Jupiter, Saturn, Uranus and Neptune.
Astronomers from the University of Warwick and the University of Valparaíso have reported the first indirect evidence of a giant planet orbiting a white dwarf star (WDJ0914+1914). It is the first time any such planet has been found.
The discovery is significant, because while there was growing evidence accumulated in the past two decades that planetary systems can survive into white dwarf stars, only smaller objects such as asteroids had been detected so far. This is the first evidence of an actual planet in such a system.
