При помощи данных из каталога GAIA

При помощи данных из каталога GAIA DR3 a также современных оценок функции масс звезд в околосолнечной окрестности будет получена полная плотность барионного вещества в околосолнечной окрестности с учетом локальной плотности звездных остатков (белые карлики, нейтронные звезды), а также с учетом околосолнечной плотности газовых дисков нейтрального и молекулярного водорода. С помощью недавних данных об отношении локальных плотностей толстого и тонкого дисков, а также данных о распределении плотностей звезд в толстом и тонком дисках Галактики и измеренной кривой вращения тонкого диска Галактики будет определен вклад темного гало в равновесную кривую вращения Галактики. С учетом недавних наблюдательных данных показывающих, что плотности тонкого и толстого дисков в околосолнечной окрестности сравнимы, это должно привести к существенному переопределению плотности темной материи в околосолнечной окрестности. При помощи данных о величине дисперсии скоростей объектов гало нами будет произведена оценка потока гипотетических частиц темной материи на поверхности Земли для ряда предлагаемых моделей, что важно для оценки ожидаемого числа событий в проводимых экспериментах по поиску частиц темной материи, в частности, в глубоководном эксперименте БАЙКАЛ.

Using data from the GAIA DR3 catalog and modern estimates of the mass function of stars in the circumsolar vicinity, the total density of baryonic matter in the circumsolar vicinity will be obtained, taking into account the local density of stellar remnants (white dwarfs, neutron stars), as well as taking into account the circumsolar density of neutral and molecular hydrogen. Using recent data on the ratio of local densities of the thick and thin disks, as well as data on the distribution of stellar densities in the thick and thin disks of the Galaxy and the measured rotation curve of the thin disk of the Galaxy, the contribution of the dark halo to the equilibrium rotation curve of the Galaxy will be determined. Given recent observational data showing that the densities of the thin and thick disks in the solar vicinity are comparable, this should lead to a significant redefinition of the density of dark matter in the solar vicinity. Using data on the velocity dispersion of halo objects, we will estimate the flux of hypothetical dark matter particles on the Earth's surface for a number of proposed models, which is important for estimating the expected number of events in ongoing experiments to search for dark matter particles, in particular, in the deep-sea BAIKAL experiment.

Using data from the Gaia DR3 catalog and modern estimates of the mass function of stars around the sun, the local density of stellar residues (white dwarfs, neutron stars) and the density of neutral hydrogen and molecular hydrogen gas disks around the sun will be taken into account to obtain the total density of baryonic matter around the sun. Using recent data on the local density ratio of thick and thin disks, as well as data on the density distribution of stars in thick and thin disk galaxies, as well as measured thin disk rotation curves, the contribution of dark halos to the equilibrium galaxy rotation curve will be determined. Considering recent observational data indicating that the density of thin and thick disks around the sun is comparable, this will lead to a significant redefinition of the density of dark matter around the sun. We will use the velocity of these objects to scatter the data

Using the data from GAIA DR3 catalogue and the modern estimation of the mass function of stars around the sun, the complete baryon material density around the sun will be obtained, taking into account the local density of star debris (white dwarfs, neutron stars) and the near-solar density of neutral hydrogen and molecular hydrogen disks. Using the recent data about the local density ratio of thick disk and thin disk, the data about the distribution of star density in thick disk and thin disk of the Milky Way, and the measured rotation curve of thin disk of the Milky Way, the contribution of dark halo to the equilibrium rotation curve of the Milky Way will be determined. In view of the recent observation data, the density of thin disk and thick disk around the near sun is equivalent, which should lead to a major redefinition of the density of dark matter around the near sun. Using the data of the extreme velocity distribution of Halo celestial bodies, we will estimate the hypothetical flow of dark matter particles on the earth's surface for a series of proposed models, which is very important for estimating the number of expected events in the ongoing dark matter particle search experiment, especially in the deep sea experiment.
