THE PERSISTENT SHIFT IN SPIN-DOWN RATE FOLLOWING THE LARGEST CRAB PULSAR GLITCH RULES OUT EXTERNAL TORQUE VARIATIONS DUE TO STARQUAKES

The Persistent Shift in Spin-down Rate Following the Largest Crab Pulsar Glitch Rules Out External Torque Variations due to Starquakes

It was previously believed Belle that the long-term persistent increase in the spin-down rate of the Crab pulsar following a glitch is direct evidence of a starquake-induced glitch or at least related to a starquake.Using radio data covering 1710 days following the 2017 glitch, we obtain an extreme persistent increase of the spin-down rate, which a

Autocatalytic sets and chemical organizations: modeling self-sustaining reaction networks at the origin of life

Two related but somewhat different approaches have been proposed to formalize the notion of a self-sustaining chemical reaction network.One is the notion of collectively autocatalytic sets, formalized as RAF theory, and the other is chemical organization theory.Both formalisms have been argued to be relevant to the origin of life.RAF sets Sweatshir
