O QUE SIGNIFICA SUPERNOVA REMNANT EM INGLÊS
Supernova remanescente
Um remanescente de supernova é a estrutura resultante da explosão de uma estrela em uma supernova. O remanescente da supernova é limitado por uma onda de choque em expansão, e consiste em material ejetado que se expande da explosão, e o material interestelar que ele varre e chove ao longo do caminho. Existem duas rotas comuns para uma supernova: uma estrela maciça pode ficar sem combustível, deixando de gerar energia de fusão em seu núcleo e colapsando para dentro, sob a força de sua própria gravidade para formar uma estrela de nêutrons ou um buraco negro; ou uma estrela anã branca pode acumular material de uma estrela companheira até atingir uma massa crítica e sofrer uma explosão termonuclear. Em ambos os casos, a explosão de supernova resultante expulsa muito ou todo o material estelar com velocidades de até 10% a velocidade da luz, ou seja, cerca de 30.000 km / s. Estes ejetos são altamente supersônicos: assumindo uma temperatura típica do meio interestelar de 10 000 K, o número Mach pode inicialmente ser \u0026 gt; 1000. Portanto, uma forte onda de choque se forma à frente da ejeta, que aquece o plasma a montante até temperaturas bem acima de milhões de K.
definição de supernova remnant no dicionário inglês
A definição de remanescença de supernova no dicionário é a casca em expansão de detritos causada pela explosão de uma supernova, que cria uma nebulosa que irradia ondas de rádio, raios-X e luz, por centenas ou milhares de anos.
