| has gloss | eng: In astroparticle physics, an Urca process is a reaction which emits a neutrino and which is assumed to take part in cooling processes in neutron stars and white dwarfs. The process was first discussed by George Gamow and Mario Schenberg while they were visiting a casino named Urca in Rio de Janeiro. Schenberg is reported to have said to Gamow that "the energy disappears in the nucleus of the supernova as quickly as the money disappeared at that roulette table." In Gamow's South Russian dialect, urca can also mean a robber or gangster. |

O processo foi pela primeira vez discutido por George Gamow e o físico pernambucano Mario Schenberg enquanto visitavam um casino denominado Urca, no Rio de Janeiro. Relata-se que Gamow terá dito a Schenberg que "a energia desaparece no núcleo de uma supernova tão rapidamente quanto o dinheiro desaparecia na mesa da rolet." No dialecto russo utilizado por Gamow, urca pode também significar um ladrão ou gangster. |

| has gloss | rus: Нейтри́нное охлажде́ние — процесс охлаждения звёздных недр образующимися в них нейтрино, которые свободно уносят энергию из всего объёма ядра, так как звезда прозрачна для нейтрино низких энергий. Скорость такого объёмного нейтринного охлаждения, в отличие от классического поверхностного фотонного охлаждения, не лимитирована процессами переноса энергии из недр звезды к её фотосфере, поэтому такой механизм охлаждения весьма эффективен. |
