Abstract:

The system of asterism in ancient China was inextricably linked with the feudal system. Starting from the origin, classification and naming methods of the asterism system, this paper illustrates the inner connection between the asterism system and the feudal system. From the philosophical perspective of "matter determines consciousness and consciousness reacts to matter", we analyze the constraints of the feudal system on the naming system of asterism and the profound influence of the system on the feudal system. The in-depth analysis of the relationship between the asterism system and the feu

Abstract:

Abstract The application of a sodium laser guide star is the key difference between a modern adaptive optics system and traditional adaptive optics system. Especially in system such as multiconjugate adaptive optics, a sodium laser guide star asterism that is formed by several laser guide stars in a certain pattern is required to probe more atmospheric turbulence in different directions. To achieve this, a sodium laser guide star asterism launching platform is required. In this paper, we introduce the sodium laser guide star asterism launching platform built and tested on the 1.8 m telescope o

Abstract:

The asterism of Veronica’s Veil reported by Rheita in 1645 is argued to be real, though inconspicuous; not a star cluster; and not correlated with Johannes Zahn’s picture published in 1686 and widely redistributed. The asterism is most likely the rectangle bounded by ρ Leonis, β Sextantis, ο Leonis, and ι Hydrae, with some scattered interior stars interpreted as a face.

AbstractIn 1677-8 Robert Boyle fell victim to a French confidence trickster, Georges Pierre des Clozets, who claimed to belong to a secret society of alchemists, 'the Asterism'; the leader of the Asterism was described as the 'Patriarch of Antioch', resident in Constantinople. New evidence shows that Georges Pierre had contrived to publish two short articles about this 'Patriarch' in a Dutch newspaper, and that one of these was given to Boyle to corroborate Pierre's claims. These articles provide further information about the nature of Pierre's invention. Most importantly, they show that his '

Abstract:

A system of 27 asterisms, or nakṣatras, plays an important role in Indian astronomy and calendrical science. The present convention is that the ecliptic is divided into 27 equal parts each 13°20' long commencing from one initial point. These arcs are called nakṣatras. Again a bright or prominent star of each division is called yogatārā bearing the name of the are division e.g., Kṛttikā as nakṣatra means an are division and as a yogatārā it means the star η Tauri of the Pleiades group.The origin of this asterism system is very old. The names of these stars appearin Vedic litrature. The Taittirī

AbstractAmong the Western Tobas of the province of Formosa, Argentina, the asterism called Dapi'chi (the Pleiades) is highly important. Traditionally, it is related to the start of the annual cycle and it is also a very significant figure in terms of its symbolic meaning. In fact, this celestial representation offers a range of insights connected to winter frosts, a type of air carnation (Tillandsia spp.–Bromeliaceae) and also to the role of the warrior.

The word Qolá also refers to a type of necklace worn by Toba leaders that – together with other insignias – represents their social rank and emblazons their prestige.

It recommends Kṛttikā as the nakṣatra or the lunar asterism under which to set up the fire. For, there are some special features that Śatapatha-Brāhmana obviously considers as good points. According to the text, one good point about Kṛttikā is that it is ′the most numerous′; secondly, it rises ′in the east′.

It is not related to a propensity for some cracked wafers to shatter during subsequent high-temperature processing. There is no correlation between crack morphology and alignment of an indenter with respect to t

The article presents the results of an ethnographic study of the traditional calendar and astronomical knowledge conducted in 2023 among the inhabitants of the Khingou River valley (Sangvor district, Republic of Tajikistan). 56 informants from 21 villages, which cover the entire currently populated part of the valley, were interviewed. The paper describes the local traditions of determining important dates of the agricultural calendar based on observations of the Sun and stars. Special attention is paid to holidays related to the agricultural cycle, such as Nowruz, Juft Baroron and the beginni

Abstract:

The asterism, or star effect, present in star sapphire (Ti-doped A12O3) single crystals is known to arise from the needle-like rutile(r) (TiO2) precipitates in the sapphire(s) matrix. The specific orientation relationship between the precipitates and the matrix is {100}r//{0003}s and <011>r//<1010>s . In this work we report a HREM study of the rutile/sapphire interface.The cross-section perpendicular to the needle axis of a very small precipitate, which is coherent, or has just one misfit dislocation at its interface, is a rhombus; the precipitate/matrix interface (habit plane) is

Abstract:

This paper presents results of SEM and EDS study in some Brazilian gemstones. Emerald from Campos Verdes (GO) contains several mineral inclusions as talc, dolomite, chromite, pyrite, magnetite, etc. Sylvite crystals was firstly identified by SEM/EDS. These salt inclusions suggest percolation of K-bearing fluids during emerald crystallization. Emerald from Campos Verdes present higher concentration of Cr+3 in the outer green zones than in the inner colourless zones, showing that ion is a chromophore in this gemstone. SEM and EDS results combined with optical microscopy analyses demonstrate that

Abstract:

Abstract The 1408 CE “guest star” recorded in Chinese historical texts presents a compelling case for identifying a historical stellar transient. While previous studies debated its nature as a meteor, comet, or nova, we reevaluate the event using original Ming Dynasty records, including a newly found memorial from the imperial court. The object, described as stationary for over 10 days, yellow, and luminous (resembling a “Zhou Bo virtue star”), is inconsistent with cometary behavior. Positional analysis locates it near the Niandao asterism (modern Cygnus–Vulpecula region) within the Milky Way,

Abstract:

Context. Open clusters (OCs) are popular tracers of the structure and evolutionary history of the Galactic disc. The OC population is often considered to be complete within 1.8 kpc of the Sun. The recent Gaia Data Release 2 (DR2) allows the latter claim to be challenged. Aims. We perform a systematic search for new OCs in the direction of Perseus using precise and accurate astrometry from Gaia DR2. Methods. We implemented a coarse-to-fine search method. First, we exploited spatial proximity using a fast density-aware partitioning of the sky via a k-d tree in the spatial domain of Galactic coor

Abstract:

This paper suggests a method for refining a massive amount of collective intelligence data and visualizing it with a multilevel sentiment network in order to understand the relevant information in an intuitive and semantic way. This semantic interpretation method minimizes network learning in the system as a fixed network topology only exists as a guideline to help users understand. Furthermore, it does not need to discover every single node to understand the characteristics of each clustering within the network. After extracting and analyzing the sentiment words from the movie review data, we
