When cosmic relationships turn toxic: How some stars feed on their companions

Cosmic relationships in space mirror human connections, with some stars locked in destructive, codependent partnerships. Binary systems featuring white dwarfs often exhibit this imbalance, where one star siphons material from its companion, leading to energetic outbursts like novae. Systems like EX Hydrae and HM Sagittae showcase these extreme interactions, where prolonged feeding can reshape space and prove fatal for one or both stars.
