Remarks
23 Nov 2010: Current spectroscopic observations are as yet insufficient to confirm the mass of planet d previuosly estimated by Holman et al. 2010 (Torres et al. 2010) 10 Sep. 2010: This candidate is inferred from the evidence of a third transit with depth ~2000 ppm. The mass estimate is inferred from the radius and a Marcus et al. 2010 model of super-Earths (Holman et al. 2010).Star
