Identification of young nearby runaway stars based on Gaia data and the lithium test
R. Bischoff, M. Mugrauer, G. Torres +6
Young nearby runaway stars are suitable to search for their place of origin and possibly associated objects, for example neutron stars. Tetzlaff, Neuhäuser & Hohle (2011) selected…
Accuracy of magnitudes in pre-telescopic star catalogues
Philipp Protte, Susanne M Hoffmann
Historical star magnitudes from catalogues by Ptolemy (137 AD), as-Sufi (964) and Tycho Brahe (1602/27) are converted to the Johnson V-mag scale and compared to modern day values f…
A Search for the modern counterparts of the Far Eastern guest stars 369 CE, 386 CE, and 393 CE
Susanne M Hoffmann, Nikolaus Vogt
In this study, we apply our previously developed method to investigate ancient transient sightings in order to derive consequences for modern astrophysical problems.We present case…

Susanne M Hoffmann
This paper summarises briefly and in English some of the results of the book Hoffmann: Hipparchs Himmelsglobus, Springer, 2017 that had to be written in German. The globe of Hippar…
Counterparts of Far Eastern Guest Stars: Novae, supernovae, or something else?
Susanne M Hoffmann, Nikolaus Vogt
Historical observations of transients are crucial for studies of their long-term evolution. This paper forms part of a series of papers in which we develop methods for the analysis…
