Description
Sympathetic eruptions of solar prominences have been studied for decades, yet identifying their causal relationships remains challenging. Here, we analyze a failed prominence eruption and subsequent mass drainage from a neighboring prominence, and investigate their potential connections. Leveraging stereoscopic observations from instruments such as LST, CHASE, and EUI, we observe that the southern prominence (PRO-S) erupts with untwisting motions, accompanied by flare ribbons, and new connections form during the eruption. Notably, the northern prominence (PRO-N) rises following PRO-S, and its upper section disappears due to catastrophic mass drainage along an elongated structure. We propose that the eruption of PRO-S was initiated by the kink instability and facilitated by flare reconnection. However, it ultimately failed to erupt due to reconnection with surrounding magnetic fields. The elongated structure connecting PRO-N overlies PRO-S, and PRO-N mass drainage is triggered by PRO-S failed eruption. This study highlights that a prominence may terminate its life through catastrophic mass drainage, where the rising motion and mass drainage reinforce each other, and the mass drainage can be initiated by an underlying eruption.
