The power in the residuals periodogram, and an extensive Monte-Carlo analysis show strong evidence for a Saturn-mass world in a habitable-zone orbit. I was thus quite excited on Saturday when the California-Carnegie group released a heavy-hitting catalog paper that includes (among many other interesting things) 256 re-analyzed Lick Observatory velocities for 51 Peg. These velocity data points are of high quality, with generally small errors. [...] [...] Back in March, I wrote about how the systemic console could be used to locate a tentative second planet orbiting 51 Peg.

There are now 256 new and updated velocities from Lick Observatory to complement the 153 published Swiss velocities. The time-series shows a well-sampled mixture of long-term cadence and intensive monitoring. [...] [...] I dug right in to see how the 51 Peg system (described in a series of posts detailed here) is holding up.

Wed, 12 Apr 2006 18:51:58 +0000 http://oklo.org/?p=61#comment-64 [...] 51 Peg c is a breaktaking, beautiful thought, but Laughlin is quick to caution that this cannot yet be described as an exoplanet discovery. Plenty of work remains to be done, and it is possible that seasonal effects having to do with the telescope used in the observation might be one alternative explanation among several. So think of that ‘room temperature Saturn’ as a gorgeous concept that may or may not pan out, but do read the Systemic entries on it as the work continues.
