TEPCat: Rossiter-McLaughlin effect observations of transiting planets

This table catalogues the Rossiter-McLaughlin effects measured for known (published) transiting extrasolar planets. This effect is normally observed spectroscopically (usually via radial velocity measurements) but can be obtained photometrically, by analysis of starspot crossing events during transits.

The Rossiter-McLaughlin effect was originally predicted by Holt (1893) and observed (but not definitively) in the eclipsing binary star systems δ Librae (Schlesinger 1910) and λ Tauri (Schlesinger 1916). It was subsequently described and clearly demonstrated by Rossiter (1924) for β Lyrae and McLaughlin (1924) for β Persei. The designation "Rossiter-McLaughlin effect" arose from the latter two papers.

All known Rossiter-McLaughlin measurements are included. Many systems have multiple measurements, often resulting from the same data. In these cases the most recent is normally the most reliable but it is important to check the published papers to be sure. I indicate the preferred value for each object using the "Pflag" column in the ASCII and CSV files (not in the HTML table below). Pflag is set to "y" for the best value for a given object, and to "n" for all other values for this object.

The quantity most commonly observed is the sky-projected angle between the axes of the stellar rotation and the planetary orbit. This quantity is normally called λ. There is an alternative definition of the co-ordinate system which yields the value β instead. The two quantities are related by λ = -β i.e. one is the negative value of the other.

The true angle between the axes of the stellar rotation and the planetary orbit is more difficult to determine, and only a few measurements exist. This quantity is called ψ and it is always as big as or bigger than the absolute value of λ: ψ ≥ |λ| This means that objects with a constraint on λ also have a constraint on ψ, but this is often not given explicitly.
