Eine neue Studie lässt vermuten das es Planeten um Weiße-Zwerge geben könnte welche sich in der HZ des Sterns befinden.
Laut den Forschern sollten sie auch leicht zu entdecken sein. Aber lest selbst :
........Agol points out that the most common white dwarfs have surface temperatures in the range of 5000 K, which leads to his calculation that a planet would need to orbit no closer than about 0.01 AU to be at a temperature where liquid water could exist on the surface. What’s intriguing from the standpoint of finding such planets is that a potentially habitable world like this, Earth-sized or even smaller, would in principle be detectable because of the small size of the host star. The white dwarf, in fact, could be completely eclipsed by a habitable planet that orbits it..................
