Using long-term optical, ultraviolet(UV) and X-ray data, we present a study of a classical T Tauri star CV Cha. The V-band light curve obtained from the All Sky
In our previous work,we developed a model to study the effects of rotation and/or tidal distortions on anharmonic radial oscillations and hence on the radial ve
Space weathering is an important surface process that occurs on the Moon and other airless bodies, especially those that have no magnetic field. The optical eff
