What. d=m/V in all cases. That article must be wrong, the planet is probably the same SIZE as Jupiter, not the same MASS. And in that case it means a surface acceleration of 20 times the one you'll find on Jupiter ie. a gravity of 50 times our own earthly attraction ie. pretty much a super-crushing force.
That or the planet is the same mass as Jupiter (2.5 times our own gravity) and it is 20 times smaller which seems doubtful for such a distant exoplanet and still makes quite a strong gravity field (you can GM/r^2 yourself)

Oh so it's my second possibility. I'm pleasantly surprised that we can reach that kind of resolution nowadays :) Still, gravity is going to be super high there.

Yeah, total squish.
The question of atmosphere is kind of interesting. Certainly the sort of large gaseous cloak you'd normally expect has been stripped away by its neutron star. And yet by the same token, the immense tidal and even magnetic forces acting on it might make it extremely tectonically active and therefore volcanic? The facing towards its star (I'm assuming it's tidally locked at that distance) might be molten, or even plasma. Liquid diamond? I don't know if that's even possible. ...Either way I highly doubt you could breathe whatever atmosphere it might have.

Aren't neutron stars deadly to anything in their vicinity anyway?

It's just because they saw it blinging.

First, we can't quite yet have the resolution to directly observe such things, but we can certainly detect their presence when they transit their star.
Second, stellar diamond is most probably more like industrial diamond; with a lot of impurities and not shiny, because even if the majority of it is carbon, the fusion process also produces other heavier elements.
Third, neutron stars are bad for your health if you lack protection from ionizing rays. You'd really need a strong magnetic field and/or something similar to the ozone layer to absorb most of the dangerous radiation and charged particles.

Diamond Planet would make a welcome distraction from usual Fire/Ice/Jungle Planet.
It`s worrying though that Bioware might think scanning planets is kewl and continue with this BS in ME3...
