超新星与盖亚

Supernovae and Gaia

Giuseppe Altavilla, Maria Teresa Botticella, Enrico Cappellaro, Massimo Turatto

摘要:

尽管几十年的努力,仍然有一些基本的问题要回答关于超新星的祖先系统和爆炸机制。特别是,在过去的几年里,一些异常明亮的物体和极其微弱的事件已经证明了一个意想不到的大型超新星品种。由下一代调查提供的大量不同红移的超新星候选者,从地面和太空,将允许更好地了解超新星事件的所有风味。特别是,它将有可能评估Ia型超新星的系统学,作为任何红移的距离指标。盖亚天体测量任务预计将发现大量瞬态事件,包括超新星,这些事件将通过瞬态警报系统立即传播给天文学界,以便采取适当的后续行动。

英文摘要:

Despite decades of dedicated efforts there are still basic questions to answer with regard to Supernova progenitor systems and explosion mechanisms. In particular, in the last years a number of exceptionally bright objects and extremely faint events have demonstrated an unexpected large Supernova variety. The large number of Supernovae candidates at different redshifts provided by the next generation surveys, from ground and space, will allow to reach a better insight of the Supernova events in all their flavours. In particular it will be the possible to assess the systematics of type Ia Supernovae as distance indicator at any redshift. The Gaia astrometric mission is expected to discover a huge number of transient events, including Supernovae, which will be immediately disseminated to the astronomical community by a transients alert system for a suitable follow up.
