A Search for recurrent novae among Far Eastern guest stars
Susanne M Hoffmann, Nikolaus Vogt
According to recent theoretical studies, classical novae are expected to erupt every ~ years, while the recurrence time scale of modern recurrent novae (N_r) stars ranges fro…
The Simulated Sky: Stellarium for Cultural Astronomy Research
Georg Zotti, Susanne M Hoffmann, Alexander Wolf +2
For centuries, the rich nocturnal environment of the starry sky could be modelled only by analogue tools such as paper planispheres, atlases, globes and numerical tables. The immer…
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…
Gaia 18dvy: a new FUor in the Cygnus OB3 association
E. Szegedi-Elek, P. Ábrahám, L. Wyrzykowski +59
We present optical-infrared photometric and spectroscopic observations of Gaia18dvy, located in the Cygnus OB3 association at a distance of 1.88 kpc. The object was noted by the Ga…
