Astrobiology: discovering new planets

Siffert, Beatriz ;

Artigo completo:

"Neste trabalho apresentaremos uma breve revisão sobre a procura por planetas fora do Sistema Solar, oschamados “exoplanetas”, no contexto da astrobiologia. Estudaremos o conceito de habitabilidade e definiremosa zona habitável estelar, região em torno de uma estrela na qual é possível ter água no estado líquido nasuperfície de um planeta rochoso. Comentaremos sobre os principais métodos de detecção de exoplanetas,sobre as características daqueles que já foram descobertos e apresentaremos exemplos de exoplanetas comparticular interesse astrobiológico. Finalizaremos descrevendo brevemente as evidências da presença de vida,as chamadas bioassinaturas, atualmente consideradas mais promissoras e as missões presentes e futuras commaior potencial para novas descobertas na área da astrobiologia."

Artigo completo:

In this work we present a brief review of the search for planets outside the Solar System, the so-called “exoplanets” in the context of astrobiology. We study the concept of habitability and define the stellar habitable zone, the region around a star in which it is possible to have liquid water in the surface of a rocky planet. We comment on the main methods of exoplanet detection, about the characteristics of those that have already been discovered, and we present examples of exoplanets with particular astrobiological interest. We conclude by briefly describing the evidence for the presence of life, the so-called biosignatures, currently considered the most promising, and the present and future missions with greater potential for new discoveries in the field of astrobiology.
