标题： A rocky exoplanet classification method and its application to calculating surface pressure and surface temperature

摘要： 在目前已检测到的5000多颗系外行星中，需要一种主要的分类方法来优先选择候选行星进行生物特征观测。 在此，我们开发了一种分类方法，根据其最接近的太阳系类比体对岩石系外行星进行分类，利用观测到的恒星和行星特征、质量以及半径的数据，对非热大气逃逸、热大气逃逸和恒星辐射边界进行建模。 将这种分类方法应用于我们样本中的720颗岩石系外行星，并通过蒙特卡洛模型传播行星质量、半径、恒星温度和通量的不确定性，结果显示，22% $\pm$ 8% 是水星类比体，39% $\pm$ 4% 是火星类比体，11% $\pm$ 1% 是金星类比体， 2% $\pm$ 1% 是地球类比体，26% $\pm$ 12% 在我们的太阳系中没有已知的类比行星。 将这种方法推广到LHS 3844b和GJ 1252b的条件，我们的分类方法结果与当前观测结果合理一致。 随后，为了展示这种分类方法的功能，我们将目录中的系外行星绘制在一个调整后的表面压力与温度相图上，提供了更现实的潜在表面相（气体、液体或冰）的估计。 我们的新分类方法可以帮助未来系外行星特征任务的目标选择。 显示英文摘要

摘要： With over 5,000 exoplanets currently detected, there is a need for a primary classification method to prioritise candidates for biosignature observations. Here, we develop a classification method to categorise rocky exoplanets based on their closest solar system analogue using available data of observed stellar and planetary features, masses, and radii, to model non-thermal atmospheric escape, thermal atmospheric escape, and stellar irradiation boundaries. Applying this classification method to the 720 rocky exoplanets in our sample with uncertainties in planetary masses, radii, stellar temperatures, and fluxes propagated via a Monte Carlo model indicates that 22% $\pm$ 8% are Mercury analogues, 39% $\pm$ 4% are Mars analogues, 11% $\pm$ 1% are Venus analogues, 2% $\pm$ 1% are Earth analogues, and 26% $\pm$ 12% are without a known planetary counterpart in our solar system. Extrapolating to conditions on LHS 3844b and GJ 1252b, our classification method gives results reasonably consistent with current observations. Subsequently, to demonstrate the functionality of this classification method, we plot our catalogued sample of exoplanets on an adjusted surface pressure versus temperature phase diagram, presenting more realistic estimates of the potential surface phases (gas, liquid or ice). Our new classification method could help target selection for future exoplanet characterisation missions.
