“…Furthermore, it can be easily seen that the variation in G required to obtain Eqs. ( 1) and ( 2) with the coefficients of the right magnitudes is consistent with observational bounds on the same [4][5][6].…”

The mass of an astrophysical object can be estimated by the amount of gravitational lensing of another object that it causes. To arrive at the estimation however, one assumes the validity of the inverse square law of gravity, or equivalently an attractive 1/r potential. We show that the above, augmented by a logarithmic potential at galactic length scales, proposed earlier to explain the flat galaxy rotation curves, predicts a larger deflection angle for a given mass. In other words, the true mass of the object is less than its estimated value. This may diminish the importance and role of dark matter in explaining various observations.

“…In order to study the dynamical evolution of these systems, we used a new code, which takes into account the evolution of the radius and spin of the central object (be it a star or brown dwarf evolving according to the evolution tracks of Chabrier et al 2000). It also includes a rigorous treatment of tidal forces (Hut, 1981;Leconte et al 2010), the effect of the rotation-induced flattening of planets and star (Correia et al 2013), the correction due to general relativity (Kidder, 1995), and planet-planet gravitational interactions using a symplectic N-body algorithm (Chambers, 1999). This code will be introduced in Bolmont et al 2015 (to be submitted).…”

A large number of observed exoplanets are part of multiple planet systems. Most of these systems are sufficiently close-in to be tidally evolving. In such systems, there is a competition between the excitation caused by planet-planet interactions and tidal damping. Using as an example two multiple planet systems, which host planets in the surface liquid water habitable zone (HZ): Kepler-62 and Kepler-186, we show the importance and effect of both planetary and stellar tides on the dynamical evolution of planets and on the climate of the HZ planets.
