AbstractSimilar to other stars, our Sun also sheds mass and magnetic flux via ubiquitous steady wind and episodic coronal mass ejections (CMEs). To investigate the mass loss rate of the Sun over different solar cycles, we exploited the remote sensing observations of CMEs near the Sun and in situ observations of the solar wind at 1 AU. We estimate the contribution of solar CMEs to the solar wind and its variation over different phases of the solar cycles. Further, we investigate that how the mass-loss rate from the Sun is related to its magnetic variability represented in terms of sunspots number and background solar X-ray flux. Our study shows that mass loss from Sun via solar wind is almost independent of cyclic variation in sunspots number and background solar X-ray flux for solar cycles 23 and 24. However, the mass-loss rate via CMEs is found to depend on solar magnetic variability, and the dependence could be expressed in terms of a simple expression. These results have significant implications for the study of solar-type stars.
