Several myths about their origins and properties have been refuted by the availability of new observations.

Varios mitos sobre sus orígenes y propiedades han sido refutados por la disponibilidad de nuevas observaciones. Presentamos el estado del conocimiento actual sobre sus eventos de nacimiento y propiedades, centrándonos en la distribución de masas, que ahora sabemos que es al menos bimodal. Argumentamos que las binarias relativistas tipo “araña” pueden producir las estrellas de neutrones más pesadas, y posiblemente los agujeros negros más livianos de la Naturaleza. El (delicado) asunto de la masa máxima se discutirá con referencia a i) determinaciones directas; ii) herramientas estadísticas y üi) análisis de eventos de ondas gravitacionales. En general, mostraremos que está surgiendo una nueva perspectiva de estos objetos.

Neutron stars today are not what they used to be. Several myths about their origins and properties have been refuted by the availability of new observations. We present the status of the present knowledge about their birth events and properties, focusing on their mass distributions, which is now known to be at least bimodal. We argue that “spider” relativistic binaries may produce the heaviest neutron stars and possibly the lightest black holes in Nature. The (delicate) issue of the maximum mass will be discussed with reference to i) direct determinations; ii) statistical tools and iii) analysis of gravitational waves events. Overall, we shall show that a new perspective of these objects is emerging. |
