Updated Gliese 436 b data

The Hubble Space Telescope observed Gliese 436 for a few transits, and we now have revised parameters.

m/sin i	0.072 MJ
Semi-major axis	0.02872 AU
Orbital Period	2.643904 days
Eccentricity	0.15
Omega	351 deg
Radius	0.438 RJ
Inclination	85.8 deg

So, Gliese 436 b is a bit bigger than Neptune. Could the extra size come from tidal heating? Interactions with a second planet in the system?

However the Super-Earth "c" has been disproven. It was too unstable to me.

As Lazarus once stated (and I agree) a 51 day periodicity observed with Systemic should be more significant.

Here is comes again. Alternative models for 2-planets fit:
