How stars die, sentence 12
A collapsing core can become a neutron star, only about 20 km across but heavier than the Sun, so a teaspoon of it would weigh billions of tonnes.
Who acts: collapsing core, teaspoon · What happens: collapse, become, weigh · To what, where: neutron star, billions
This is a sentence of the lesson «How stars die» of the space course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (collapsing core, teaspoon), what happens, when and where, as Mova's frames read it from the tree.
