Transit search for HD 156846 b

After HD 80606 b, another highly eccentric planet to search for transit. If detected, transit could definitely ascertain whether this object is planetary either stellar object (m=0.17 M_Sun) as suggested by very low inclination found by Reffert & Quirrenbach (2011).

Improved Orbital Parameters and Transit Monitoring for HD 156846b

Quote :

HD 156846b is a Jovian planet in a highly eccentric orbit (e = 0.85) with a period of 359.55 days. The pericenter passage at a distance of 0.16 AU is nearly aligned to our line of sight, offering an enhanced transit probability of 5.4% and a potentially rich probe of the dynamics of a cool planetary atmosphere impulsively heated during close approach to a bright star (V = 6.5). We present new radial velocity (RV) and photometric measurements of this star as part of the Transit Ephemeris Refinement and Monitoring Survey (TERMS). The RV measurements from Keck-HIRES reduce the predicted transit time uncertainty to 20 minutes, an order of magnitude improvement over the ephemeris from the discovery paper. We photometrically monitored a predicted transit window under relatively poor photometric conditions, from which our non-detection does not rule out a transiting geometry. We also present photometry that demonstrates stability at the millimag level over its rotational timescale.

*Peronally I hope it gets "re-habilitated" as planet*

According to EPE, the 3σ mass range is 10.45 Jupiter masses to 660.9... could still be planetary, so seems worthwhile to check this one for transits.
