在这项工作中，考虑了各种因素对宜居性的影响，重点放在与中央恒星的辐射无关的条件下，以了解具体的行星体相关影响的作用。对这些所谓的行星因素进行了评估，以确定那些重要信息缺失但很有可能被未来十年可能获得的新知识填补的跨域问题(S)。在这些战略知识空白中，列出了具体问题，如恒星形成区中放射性核素的出现，根据体积参数和特定系统的演化背景估计地下液态水的存在的模型，根据环境类型估计氧化还原梯度的存在等。根据我们目前的知识，地下宜居性可能至少与地表宜居性一样频繁，或者更频繁。不幸的是，通过观察推断地下宜居性的条件更加困难，但具体的论证可能有助于间接的方法，这可能导致从总体上探讨宜居性的新方法。
In this work various factors on the habitability were considered, focusing on conditions irrespective of the central star’s radiation, to see the role of specific planetary body related effects. These so called planetary factors were evaluated to identify those trans-domain issues where important information is missing but good chance exit to be filled by new knowledge that might be gained in the next decade(s). Among these strategic knowledge gaps, specific issues are listed, like occurrence of radioactive nucleides in star forming regions, models to estimate the existence of subsurface liquid water from bulk parameters plus evolutionary context of the given system, estimation on the existence of redox gradient depending on the environment type etc. These issues require substantial improvement of modelling and statistical handling of various cases, as “planetary environment types”. Based on our current knowledge it is probable that subsurface habitability is at least as frequent, or more frequent than surface habitability. Unfortunately it is more difficult from observations to infer conditions for subsurface habitability, but specific argumentation might help with indirect ways, which might result in new methods to approach habitability in general.
