Pion condensates in the Vela pulsar and the energetics of its glitch events

Pion condensates can help to explain a variety of physical properties owned by pulsars if they are present in their interiors. It has been noted that they offer, for example, an attractive alternative to understand glitches by improving former core-quake models. We discuss this scenario and show in this work some constraints on the properties of this type of matter arise from X-ray observations of the Vela pulsar performed by theEinstein Observatory. Further information on this subject will be soon obtained from improved facilities and we expect them to give further constraints to the viability of those models.
