Magellanic Clouds' Binaries as Distance Indicators

2001
Detached eclipsing binary systems of B-type stars in the Large and Small Magellanic Clouds have been observed in order to determine distances to these galaxies. We obtained high resolution spectra using the UVES spectrograph at the VLT, ESO. Analysis of the spectra with strongly overlapping spectral lines, which are heavily broadened by the Stark ...

Distance Indicators: Beyond Distances — A Return to Astrophysics

1995
Continuing progress in the development, application, and physical understanding of distance indicators is likely to yield a generally accepted value for the Hubble constant during the VLT construction years. Thus, the VLT’s contribution to that highly visible subfield is unlikely to be pivotal.

On Relations between Distance-Based Topological Indices

Match Communications in Mathematical and in Computer Chemistry
Motivated by the recent paper On topological indices and their reciprocals, MATCH Commun. Math. Comput. Chem. 91 (2024) 287, we establish additional relations between distance- and degree-and-distance-based molecular structure descriptors: Wiener, hyper-Wiener, Harary, connective eccentricity, eccentric connectivity, degree distance, Gutman, additively

Distance-based topological indices and double graph

2017
Summary: Let \(G\) be a connected graph, and let \(D[G]\) denote the double graph of \(G\). In this paper, we first derive closed-form formulas for different distance based topological indices for \(D[G]\) in terms of that of \(G\). Finally, as illustrative examples, these formulas are applied to several special kinds of graphs, such as, the complete ...
