Assessing the Habitability of the TRAPPIST-1 System Using a 3D Climate Model

Concludes that only one of the seven ("e") may have the right conditions to maintain liquid water, but also assumes for reasons that aren't clear to me that all seven planets start out as water worlds.

The stability of tightly-packed, evenly-spaced systems of Earth-mass planets orbiting a Sun-like star

"...we show that isolated systems of up to five Earth-mass planets can fit in the habitable zone of a Sun-like star without close encounters for at least 10^9 orbits."

Still not Whedon's 'Verse, though.
