Summary of stellar activity-related information for the XO-2 system.
|log ()||−4.91 ± 0.01||−5.02 ± 0.01|
|Exp. stellar rot. period [days]||39.6 ± 0.6 [N84]||41.1 ± 0.7 [N84]|
|41.8 ± 0.8 [M08]||44.7 ± 0.7 [M08]|
|Meas. stellar rot. period [days]||41.6 ± 1.1||26.0 ± 0.6 (or 34.5 days)|
Notes. The values of the activity index ) are given as weighted mean, and the uncertainty of each parameter is the standard deviation of the mean. The estimates for the stellar rotation periods correspond to two different relations, those of Noyes et al. (1984) [N84] and Mamajek & Hillenbrand (2008) [M08].
