Next, they park at the L2 of the planet-blackhole system and make a trip to the plant because the time gradient is so strong that entering low orbit would be catestrophic. I question how such a planet is not volcanic with such forces at play and even be a candidate planet...
IIRC, it was claimed that the first planet had a 30% higher surface gravity than that of Earth, while time passed seven times faster on Earth. My back-of-the-envelope calculations based on the latter property puts this "planet" in white dwarf to neutron star territory.

The first planet surface gravity was 30% higher, IIRC; however the passage of time was more like 1 hour to several decades. They were there like 45min and 23 years elapsed on the orbiting ship.
