How stars die, sentence 8

What remains of a Sun-like star is a white dwarf, about the size of the Earth but with roughly half the Sun's mass, so a teaspoon of it would weigh several tonnes, more than a car.

Who acts: white dwarf, teaspoon · What happens: remain, be, weigh · To what, where: white dwarf, several tonnes

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 (white dwarf, teaspoon), what happens, when and where, as Mova's frames read it from the tree.
