Their mass is bounded above by the (*) Tolman-Oppenheimer-Volkoff limit and they were originally discovered in Scorpius.
The first exoplanets were discovered orbiting a sub-type of these objects. Star quakes in their crust cause glitches in these objects. Ones with unusually strong magnetic fields are called magnetars. Their mass is bounded above by the (*) Tolman-Oppenheimer-Volkoff limit and they were originally discovered in Scorpius. The one in the Vulpecula was mistaken for "Little Green Men,", but was later determined to be a pulsar, a sub-type of these objects. These objects are the remains of core-collapse supernovae and are composed of a namesake degenerate gas. For 10 points, name these celestial objects that are composed of uncharged particles that are normally found in atomic nuclei.
