There exist huge chunk of academic items receiving no citation years after years and remaining beyond the veil of ignorance of the academic audience. These are known as uncited items. Now, the question is, why a paper fails to get citation? The attribute of incapability of receiving citation may be termed as Uncitedness. This paper traces brief history of the concept of uncitedness sprouted first in 1964 in an article entitled Cybernetics, homeostasis and a model of disease by Gerson Jacobs. The concept of uncitedness was scientometrically first explained by Garfield in 1970. The uncitedness of twelve esteemed Indian physics and astronomy journals over a twelve years' (2009-2020) time span is analysed here. Besides Uncitedness Factor (UF), three other indicators are introduced here, viz. Citation per paper per Year (CY), h-core Density (HD) and Time-normalised h-index (TH). The journal-wise variational patterns of these four indicators, i.e. UF, CY, HD and TH and the relationships of UF with other three indicators are analysed. The calculated numerical values of these indicators are observed to formulate seven hypotheses, which are tested by F-Test method. The average annual rate of change of uncited paper is found 67% of total number of papers. The indicator CY is found temporally constant. The indicator HD is found nearly constant journal-wise over the entire time span, while the indicator TH is found nearly constant for all journals. The UF inversely varies with CY and TH for the journals and directly varies with TH over the years. Except few highly reputed Indian journals in physics and astronomy, majority other journals face the situation of uncitedness. The uncitedness of Indian journals in this field outshines the same for global journals by 12%, which indicates lack of circulation and timely reach of research communication to the relevant audience.

通过一些 h 型指标的棱镜审查选择性印度物理学和天文学期刊的未引用率

存在着大量的学术项目年复一年地没有被引用，并且超出了学术观众的无知之幕。这些被称为未引用项目。现在的问题是，为什么一篇论文没有被引用？不能接受引用的属性可称为未引用。本文追溯了 Gerson Jacobs 于 1964 年在一篇题为“控制论、体内平衡和疾病模型”的文章中首次提出的未被引用概念的简要历史。Garfield 于 1970 年首次从科学计量学上解释了未被引用的概念。这里分析了十二年（2009-2020）时间跨度内十二种受人尊敬的印度物理学和天文学期刊的未被引用。除了未引用因子 (UF)，这里还介绍了其他三个指标，即。每年每篇论文的引用次数 (CY)，h 核密度 (HD) 和时间归一化 h 指数 (TH)。分析了UF、CY、HD、TH这四个指标在期刊上的变化规律以及UF与其他三个指标的关系。观察这些指标的计算数值，提出七个假设，并通过F-Test方法进行检验。未引用论文的年均变化率占论文总数的67%。发现指标 CY 在时间上是恒定的。在整个时间跨度内，指标 HD 在期刊方面几乎保持不变，而指标 TH 在所有期刊中几乎保持不变。UF 与期刊的 CY 和 TH 成反比，多年来与 TH 直接变化。除了少数在物理和天文学方面享有盛誉的印度期刊外，其他大多数期刊都面临着未被引用的情况。
