Uncertainties in Historic Visual Double Star Measures—III Accurate Calibration Pairs

Astronomische Nachrichten, EarlyView.
ABSTRACT Based on space‐based positions and proper motions, we present accurate rectilinear elements for 857 double star pairs over the celestial sphere. These elements allow for the computation of precision ephemeris Position Angles and Separations of these pairs.

A Proposed Circular Economy Readiness Framework for the Rail Sector, A Literature Review and Conceptual Framework

Business Strategy and the Environment, EarlyView.
ABSTRACT The circular economy (CE) offers a transformative approach to addressing global sustainability challenges, yet few frameworks integrate it with business strategy, systems thinking (ST) and asset management (AM), especially within critical infrastructure sectors like rail. This paper conducts a comprehensive literature review to assess existing
