Clusters of this kind have a well-developed internal structure that is topologically similar to the structure of porous catalysts, adsorbents, and carriers used in the organic synthesis technology. On the other hand, observational data currently obtained by such instruments as the Atacama Large Millimeter/submillimeter Array (ALMA) show that complex preorganic compounds rather than only water and volatiles are present in protoplanetary disks. This suggests the possibility that, in protoplanetary disks, there are mechanisms of capturing complex chemical compounds by porous dust clusters and transporting these compounds to warmer regions during migration. When getting to warmer regions of protoplanetary disks, dust clusters undergo a change in the pore space, which may increase the surface holding the captured compounds and, hence, intensify their reactivity.</p>","PeriodicalId":778,"journal":{"name":"Solar System Research","volume":"58 1 supplement","pages":"S40 - S49"},"PeriodicalIF":0.6,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142679826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the vast majority of astrobiological experiments, a very limited set of organisms and the impact of a small number of factors are studied. It seems natural that research gradually develops from modeling simple systems (pure cultures and single-factor impacts) to more complex ones, closer to hypothetical extraterrestrial ecosystems. Nevertheless, studies of the most complex systems (microbial communities under the complex action of extraterrestrial conditions in laboratory and space experiments) are still extremely few in number. At the same time, some features of multifactor impacts and the response of complex microbial systems to such impacts are often given little attention.

When considering the Euler–Lambert problem as the inverse problem of ballistics (dynamics), we have succeeded in developing a new effective method for determining the orbit corresponding to a given flight time. It is logical to name this approach the Okhotsimsky–Egorov method. In the considered approach, the parameter of the set of flights is the initial flight-path angle. The advantages of the proposed method are the limited and understandable structure of the domain of definition of solutions, the simplicity and clarity of the algorithm, and the clear dependence of the solution on the initial velocity. It enables a qualitative analysis of flight trajectories and the construction of effective numerical methods. To solve the Euler–Lambert problem Halley’s numerical method was used.
