| Abstract: | We present the results of X-ray luminosities of some active late-type stars, based on data primarily from the ROSAT position
sensitive proportional counter (PSPC). According to the observations, we divide the stars into four groups: single, wide binary,
binary and RS CVn. We investigated the correlation between the X-ray emission and the hardness ratio, coronal temperature,
magnetic field strength, magnetic flux density. Our results suggest that the magnetic field plays a very important role in
stellar X-ray emission. |
