It has been shown that the empirical criterion from the work (Domingos et al., 2006), which is often used to determine potential orbits of exomoons (satellites of exoplanets), significantly overestimates the value of acrit. In a planar problem for a prograde orbit (the directions of orbital motion of the planet and satellite coincide) of an exomoon, when estimating acrit the criterion proposed by Rosario-Franco et al. (2020) works better, for the retrograde orbit of the exomoon, the criterion from the work (Quarles et al., 2021) works better. If the angle between the orbital planes of the planet and the satellite can be significant (>30°), a reliable estimate for acrit can be obtained by numerical modeling of the long-term orbital dynamics of the exomoon and using rigorous methods of motion stability analysis (calculation of Lyapunov characteristic exponents, the MEGNO parameter, etc.).","PeriodicalId":778,"journal":{"name":"Solar System Research","volume":"60 :","pages":""},"PeriodicalIF":0.8,"publicationDate":"2026-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147796370","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}

Analytical description of these distributions is carried out using the method (Brykina and Egorova, 2021), which expresses the cumulative number of fragments depending on the fragment mass, the total mass of fragments, the mass and number of maximum fragments and a free parameter—the power index. We described the results of impact experiments on the disruption of the Allende, Mbale, NWA 620, MOR 001 meteorite samples and Mauna Loa basalt samples available in the literature. We constructed and described the distributions of the Bruderheim, Villalbeto de la Peña, St-Robert, and Motopi Pan meteorites, recovered after observed passages of cosmic bodies through the atmosphere, as well as the distributions of meteorites whose falls occurred thousands of years ago: the Gold Basin, Jiddat al Harasis 073, Whitecourt, Campo del Cielo, and Canyon Diablo. The results of the description of experimental distributions confirm the previously proposed analytical dependence of the power index on the specific impact energy. Based on the description of fragment mass distributions for 22 meteorite falls, the dependence of the power index on the number of fragments in a meteorite collection is analyzed. The features of various distributions are pointed out.","PeriodicalId":778,"journal":{"name":"Solar System Research","volume":"60 :","pages":""},"PeriodicalIF":0.8,"publicationDate":"2026-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147707781","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}

The use of halo orbits near collinear L1 and L2 libration points, which are located at a distance of one and a half million kilometers from Earth, for the purpose of studying asteroids has three important advantages compared to previously implemented missions. Firstly, the trajectories of potentially hazardous asteroids approaching the Earth may pass by these libration points. Obtaining new scientific information about celestial bodies of this type is the most preferable in the context of the problem of asteroid–comet hazard. Secondly, the asteroid’s approach to both Earth and the spacecraft occurs at close moments in time, which could ensure the latter’s flight at a minimal distance from the surface of the celestial body and lead to the acquisition of fundamentally new data about the object of study. Thirdly, after approaching the asteroid, the spacecraft continues to operate near the libration point and can be used to solve other scientific problems. Using the example of the flight to the asteroids Apophis, 2001 WN5 and 1997 XF11, the results of calculations of such orbits for spacecraft that are already operating near the L2 Sun–Earth libration point are presented (James Webb Space Telescope, Euclid and Spectrum-Roentgen-Gamma). The values of the characteristic velocity required to perform a maneuver of this type demonstrate the potential of the proposed concept.","PeriodicalId":778,"journal":{"name":"Solar System Research","volume":"60 2","pages":""},"PeriodicalIF":0.8,"publicationDate":"2026-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147737410","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 this paper, we consider a spontaneous recombination of radicals accumulated in water ice as a potential energy source, which could lead to liquid water formation beneath an icy body’s surface. We simulated the propagation of the recombination process through a small, 1-km-radius icy body with an initial temperature of 10 K consisting of amorphous ice, dust, and volatile gases trapped in the amorphous ice. Our results show that the recombination front rapidly propagates throughout the body, outrunning all other processes, including gas diffusion. If a sufficient concentration of radicals accumulates, the temperature and the pressure behind the recombination front could be sufficient to the formation of liquid water inside the icy body. The time during which these conditions can be maintained inside the body is determined by the diffusion of the gases released from the amorphous ice. For a 1-km body with a porosity of 0.65 and a dust-to-ice mass ratio of 1, this time is approximately 50 years. The recombination process weakly depends on the initial temperature of the icy body and can occur at very large heliocentric distances, including comets in the Oort cloud.","PeriodicalId":778,"journal":{"name":"Solar System Research","volume":"60 2","pages":""},"PeriodicalIF":0.8,"publicationDate":"2026-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147737413","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}

To address this problem, an attempt was made to apply convolutional neural networks (CNNs) to automatically classify orbital resonances based on graphical representations of critical arguments. It is shown that the model trained on the resonance argument plots obtained for objects from the 1 : 2 orbital resonance region demonstrated high accuracy on test data from this resonance region but showed a significant decrease in performance when applied to other resonance regions of 2 : 1 and 3 : 1 due to the presence of previously unseen graphical examples. After retraining the model on a more diverse dataset including all three resonance regions investigated, a more accurate model was developed, achieving an average classification accuracy of 98%. The study not only confirmed the high effectiveness of CNN for automating resonance classification but also highlighted the critical importance of using a diverse training dataset to build a highly accurate classification model.","PeriodicalId":778,"journal":{"name":"Solar System Research","volume":"60 2","pages":""},"PeriodicalIF":0.8,"publicationDate":"2026-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147737416","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}
