astronomiline

Astronomiline is a neologism occasionally used to describe the study of line-like aspects in astronomical data. It is not an established discipline with a formal definition in major scientific literature. Generally, the term is used to refer to two related strands: spectral-line analysis and the study of linear features in astronomical images or datasets.

In the spectral sense, astronomiline would involve interpreting spectral lines to infer the chemical composition, temperature, density, motion, and physical conditions of celestial sources. This includes identifying lines, using line ratios as diagnostics, and applying radiative transfer concepts. The approach overlaps with standard spectroscopy and astrochemistry, but the neologism is sometimes invoked to highlight a line-centered perspective on data interpretation.

In imaging and time-domain data, astronomiline can describe the detection and analysis of elongated or linear structures such as jets from young stars or active galactic nuclei, filamentary features in molecular clouds, or linear distributions in orbital parameter space. Techniques associated with this sense include image processing, line detection methods such as the Hough transform, and linear feature extraction in time-series data.

Usage of the term varies, reflecting its status as a nonstandard label rather than a formal field. Some writers employ astronomiline in educational or exploratory contexts to draw attention to the central role of lines and linear structures in astronomical observations, while others see it as a playful or speculative term rather than a precise scientific category.
