Abstract

In the present manuscript we consider the possibility of conducting SETI with small-size (with diameters less than 1 m) optical telescopes. Calculations are performed for typical parameters of the mentioned type of telescopes. In particular, we show that the techno-signatures of Type-2.x and Type-3.x civilizations might be detected. It is demonstrated that it is possible to detect hot megastructures (up to 4000 K) built around Main Sequence stars and pulsars, as well as von Neumann extraterrestrial probes.

小型光学望远镜对SETI的展望

在本文中，我们考虑了用小尺寸(直径小于1米)光学望远镜进行SETI的可能性。对这类望远镜的典型参数进行了计算。特别地，我们证明了2型的技术特征。x和Type-3。X文明可能被探测到。它被证明有可能探测到建造在主序星和脉冲星周围的热巨型结构(高达4000 K)，以及冯·诺伊曼外星探测器。
