By analyzing two sets of complete BV Rc Ic light curves for V342 UMa and three sets of complete BV Rc Ic light curves for V509 Cam, we determined that the two s
The angle between planetary spin and the normal direction of an orbital plane is supposed to reveal a range of information about the associated planetary format
We investigate the evolutions of two prominences(P1, P2) and two bundles of coronal loops(L1, L2), observed with SDO/AIA near the east solar limb on 2012 September
