The info could be about previously found gas giants in the h-zone, but with eccentric orbits. They were debating whether or not these gas giants could harbor moon companions.

There's also this one:

[Another planet, about the mass of Jupiter, was found in an Earth-like orbit around a star that is almost identical to our Sun.

Its orbit would be in the so-called "habitable zone" where the conditions would be right for the presence of liquid water, an essential ingredient for life. Although the Jupiter class planet would have no solid surface, any rocky moons it may have may possibly have oceans.]

They may have found some planets among this system:

[The star 47 UMa is a yellow G0V star very similar to the Sun, probably about 7 billion years old and located about 51 light years from Earth. Fischer noted that the so-called habitable zone around the star -a region approximately equivalent to that between the orbits of Venus and Mars in our solar system, an area that includes Earth - is devoid of large gaseous planets. This means it potentially could harbor an Earth-sized rock we can't yet see, and won't be able to see until NASA launches the next generation of planet hunting missions from space.]

It's not always about what is actually seen. Anyways, yes, looks like they are debating about something. *g*
