A NON-EMPIRICAL ROTATION-ACTIVITY RELATION FOR RS CVn BINARIES USING RADIO LUMINOSITIES
نویسنده
چکیده
An analysis of a comprehensive survey of radio luminosities for RS CVn binary systems is given. A comparison is made between the rotation-activity correlations found using the usual semi-empirical Rossby number and a Rossby number deduced from detailed convection zone models. The use of a non-empirically derived Rossby number does not signiicantly improve the rotation-activity correlation. Although there are some indications that the rotation-activity correlations are marginally better for theoretically derived convective parameters this study is limited by the size of the sample.

Supersaturation in X-ray emission of clusters stars
A population of cool dwarfs with extreme rotational velocities (vsin i ∼ > 100 km/sec) is present in young open clusters. ROSAT observations have shown that these very fast rotators exhibit a level of X-ray activity a factor of 3–5 below the saturated level which is usually observed (both in X-rays and other magnetic activity indicators) for ‘normally’ fast rotators. This phenomenon has been de...
متن کاملA Study of the Coronal Plasma in RS CVn binary systems
XMM-Newton has been performing comprehensive studies of X-ray bright RS CVn binaries in its Calibration and Guaranteed Time programs. We present results from ongoing investigations in the context of a systematic study of coronal emission from RS CVns. We concentrate in this paper on coronal abundances and investigate the abundance pattern in RS CVn binaries as a function of activity and average...
متن کاملAlignment of rotational axes in asynchronous late type binaries
41 RS CVn and BY Dra type binaries with reliable orbital and physical parameters have been found to rotate asynchronously with the orbital revolution. For this sample inclinations of the rotational axes, ir, of the primaries and the orbital inclinations, io, are independently determined to test the alignment between the equatorial and the orbital planes. The observed difference ∆i = |io − ir| m...

متن کاملChromospherically Active Stars in the Galactic Bulge
We present the results from the discovery and study of ∼ 3000 chromospherically active giant and subgiant stars toward the Galactic bulge. We find that these stars are predominantly RS CVn binaries with rotation periods between 10 and 100 days. We discover that the average rotational period of these stars decreases with their distance from the Galactic plane. We find that the primary stars in t...
